Food Industry - this is multi-profile, effective and the most important industrial potential for Georgia, on its development is greatly depended the solution of problems of social and national-ethnical relationships existing in country. Last years’ experience showed that in foreign countries there is not big demand on none of the traditional food products produced in Georgia. European and American markets are satiated with table wines and fruit-berry juices, other traditional food products that’s why the actual topic is to investigate the new directions, in order to produce the competitive products with using the local raw materials. Study of the world’s leading as well as the post-soviet countries’ agricultural complex development experience leaded us to the conclusion that the reviving of Georgia’s agricultural complex will be impossible without the cluster development of this field, and the most acceptable form is technopark.

| 1.6/2018 | Working out the scientific development strategy in food and processing industry | State targeted program | Ministry of education and science of georgia | 0 | 01/01/2018-31/12/2023 | Nugzar Baghaturia | Gennadi Baghaturia Mariam Loladze | The data given in literature allows us to conclude that: • Scientific sphere in Georgia is less priority for Government; • Governmental management structure of scientific system doesn’t correspond to the accepted model by international practice; • The strategic view of scientific infrastructure optimization does not exist, rehabilitation activities are not enough; • Integration frame and aims are not determined; synergy effect received as a result of this process is insignificant; • Monitoring of scientific activity and evaluation system doesn’t exist. | The main element of scientific research and development in Georgia are scientific-research institutions, which on 100% are based on governmental estate and belong to the corresponding profile universities as an independent structural unit. On the same percentage ration its existence depends on governmental budget funds. Data shows that from the counted countries in terms of funding Georgia is on the lowest level. Here in gross domestic product inner costs on scientific-research and trial-design works are not more than 0,3%. As government is interested in the development of state-private partnership (SPP) forms and mechanisms, should provide the achievement of the following aims: 1. Growth of intellectual, technological, material and financial potential of education and science, as a term of country’s economic stable growth; 2. Improvement of managing efficiency factors of science and high professional education, implementation of state funds with more efficiency; 3. Provision of competitiveness of high educational and scientific organization institutions, stimulate the approachment of fundamental and applied sciences; 4. Satisfaction of dynamic changing demand on labor market, strengthen the innovative component of education and science. The main interest of business sector in state private partnership are: 1. To get the economical profit from the fulfilment of partnership projects; 2. Increase the business competitiveness; 3. Growth of professionalism of labors in private sector; 4. Growth of efficiency and quality of scientific research results implementation; 5. Widening of innovative business possibilities and etc. | Monograph |
| 1.2/2018 | Research of innovative technology of red semi-sweet wines enriched with antioxidants | State targeted program | Ministry of education and science of georgia | 0 | 01/01/2018-31/12/2023 | NAna Ebelashvili | Eteri Uturashvili Inessa Kekelidze Maya Demeniuk | In order to increase the phenol admixtures concentration, to make test samples of red semi sweet wine, for the first time by us was used the technological ways separately and combined: before conducting alcoholic fermentation, taking off the different parts of grape juice from must; must warming up | The object of research was red semi-sweet wines control and four test samples made of Saperavi. The control sample was made with existing (standard) technology: alcoholic fermentation of seedless must on 25-28 0C using dry yeast; pressing out of fermenting must, when unfermented sugar amount is 8-9%, storage of fermenting grape juice on low temperature, decanting of wine material from sediment when unfermented sugar amount is 5% and its storage on low temperature using sulfurous dioxide (30mg/l). Test sample №1 – worming up of the seedless must on 650C, after must was cooled down to 250C its alcoholic fermentation and following technological processes were conducted similarly as on control sample. Test sample №2 – taking off the half mass of grape juice from seedless must, left must’s alcoholic fermentation and following technological processes were conducted similarly as on control sample. Test sample №3 – taking off the half mass of grape juice from seedless must, worming up of left must on 650C, after must was cooled down to 250C its alcoholic fermentation and following technological processes were conducted similarly as on control sample. Test sample №4 – taking off the 1/3 of grape juice from seedless must mass, worming up of left must on 650C, after must was cooled down to 250C its alcoholic fermentation and following technological processes were conducted similarly as on control sample. In current year (third year from preparing the sample) the research object’s taking off from sediment took place twice (once in 6 month) and investigation of their chemical features (sum amount of phenol substances, titratable acidity, . . . . . acidity, active acidity, alcohol, coloring intensity and tonality). Research results showed that due to wine stone formation and extraction process, the titratable acidity amount in third year of semi-sweet wine samples noticeably reduced, accordingly changed the active acidity amount. During third year slightly occurs change of . . . . acidity and reduction of alcohol indexes; Reduction of alcohol must be explained with its participation in etherification process during storage. Also insignificantly reduces the sum amount of phenol substances, coloring intensity and tonality. Sum amount of phenol substances reduces as a result of rusting, polymerization, forming of protein-tannate and moving process of these components to sediment that runs with comparatively slow intensity on third year samples are made. With high compound of phenol components and better degustation indexes is characterized the test sample №3. During making of this one were used the technological ways: before alcoholic fermentation taking off the half of seedless must and warming up of left must on 650C. The sum amount of total phenols in it is 2 times higher in comparison with control one. At the end of third year after making phenol substances sum amount is higher than control sample, also in other test samples: in sample №1 – with 35%; sample №2 – with 88 %; in sample №4 - 1,8 times. The research results of the current year as last years research results showed that in the semi-sweet wine making technological process before alcoholic fermentation taking off the half of seedless must and warming up of left must on 650C significantly increases the phenol substances concentration in wine that accordingly increases the prevention effect of cardiovascular, tumor and lot of other diseases. | technological instruction |
| 1.3/20017 | Research of scientific basis of Georgian whisky production technology | State targeted program | Ministry of education and science of georgia | 0 | 01/01/2017-31/12/2023 | Nugzar Baghaturia | Elene Kalatozishvili Louisa is right Louise Kajaya Giorgi Grigalashvili Mariam Loladze | In institute there is worked out the production technology of white whisky. During last years white whisky is popular in USA. The sense of technology is that end product is received by cleaning the distillate of cereal cultures. Received white distillate is the end product. The technology we offer presents the production of aromatized white whisky. As aromatizes are used the natural essential oils. The receiving process of distillate from Georgian variety of corn and wheat and establishing of their chemical composition is undergoing. | In table 7.1 are given the chemical compositions (control) of wine distillates received from Rkatsiteli grape processing, in table 7.2 – compositions of distillates (whisky distillates) received from wheat distillation. | technological instruction |
| 1.3/2018 | Work out the composition of spices for the boiled sausage production on the basis of Georgian spice-aromatic raw material, their production and usage technologies | State targeted program | Ministry of education and science of georgia | 0 | 01/01/2018-31/12/2023 | Nazi alkhanashvili | Maia Demeniuki | On the basis of researches conducted for the boiled sausage in order to make composition there were selected spices traditionally produced and widely spread in Georgia; Coriander seeds, capsicum (red pepper), Utskho Suneli, parsley seeds, celery seeds, dill seeds, laurel seeds, from the classical spices there was selected nutmeg | In order to dry raw spices the technological equipment plays the determinative role to maintenance their organoleptic features and increase the time of storage. In Georgia to dry the local raw mono-spices there was used the five conveyer drier equipment СПК-4 Г, Г-4 КСК, CKO made in Russian Federation, Belgorod. Innovative technological equipment to dry the raw spices and mix them is worked out by the firm Amixon (Germany). This firm produces the multifunctional mixers that in case of necessity during mixing provides also drying. Given equipment provides the high quality of raw spice drying, during the minimal time of mixing. In order to maintain the organoleptic features mono-spices should be stored maximally on 5-120 and relative humidity 65-70%; Storage where spices and spice compositions will be kept should ventilate quite well. The hermetic storage of mono-spices (each separately) is advisable. The storage period for the selected mono-spices for the boiled sausages is 1 year. The technological scheme of the spice composition production for boiled sausages consists of the following main processes: to get the dried mono-spices, to prepare the mono-spices for mixing, mix the components, sort and pack. The receiving of the mono-spice each component takes place according to the appropriate technical conditions. Preparatin of mono-spices to mix. The inspection of dried, milled mono-spices takes place separately on different inspection transporter or inspection table. During this from the main mass of mono-spices separates the damaged, roughened parts and admixture from outside. Dried mono-spices are separately milled on hammer grinder (miller КДМK-2, or grinder ДКУ-УА,Ф-УМ, pepper miller ПП-01, or other types of grinders). The milled mass of dried spices are separately sifted №0,45 and № 0,95. Mass left on sift is grinded second time and are sifted in the same sifts. The grinding process continues till the mass left on sift №0,95 is 2%, and mass passed through sift № 0,45 not less than 80%. In order to separate the magnetic admixtures from the milled mono-spices sifted mono-spices are separately passed in magnetic separator. Before making composition the mono-spices prepared with above reviewed way prepared milled mini-spices separately are places in four-layered craft-bags and store in storerooms on 5-120 temperature and 65-70% relative humidity conditions. Mixing the components to make spice compositions for boiled sausages. Milled and dried mono-spices are weighted on ВЛТК-5 type squared electro weights (with the measuring scale limits0-5kg, grade of accuracy 0,2) in accordance with composition recipe and mix with each other in drum type mixer for 10-15 minutes before they get homogenous mass, after that composition is weighted, sorted and packed. While making a composition loss of milled mono-spices during weighting, mixing and packing is 3,5%. | technological instruction |
| 1.5/2017 | Research of the new technology of vodka production from Chacha | State targeted program | Ministry of education and science of georgia | 0 | 01/01/2017-31/12/2023 | Nugzar Baghaturia | Mariam Loladze Elene Kalatozishvili Lia Kotorashvili Medea Ormotsadze | In order to increase the competitiveness and improve quality of Georgian drink Chacha made from grapes, there is worked out the principally new technology in the instate that foresees the reception of distillate from the grape juice wine-material fermented on must. There is investigated the dynamic of evaporative components moving to distillate during the distillation of white grape chacha fermented with Kakhetian way. There is shown the moving characteristics of ethyl alcohol and admixtures during distillation. There is selected the optimal technological mode of grape brandy alcohol distillation, are established the chemical compositions of first-distilled, mid-distilled and last-distilled fractions. | From data we see that the ethyl alcohol composition in distillated fractions regularly decreases. What about admixtures – aldehydes and ethers, the curves expressing their composition are not similar, that shows the chemical changes, which take place during the distillation by the influencing of different factors. The movement of evaporating admixtures to distillate does not defend only on fermentation temperature and concentration, but also on their dissolubility in water-alcohol solutions. This last is depended on the composition of raw alcohol. Thereby the chemical composition of grape juice fermented on must is noticeably different from the composition of wines fermented in European way, this factor significantly influences on the chemical composition and features of wine distillate. Single-distilled unfiltered vodka’s (rakhi) oil is presented with the isoamyl, isobutyl and octyl alcohol. Main component from these is isoamyl alcohol. From the data of pic 5.2 we can see that rakhi oil content in the initial fraction firstly increases and then decreases, reaches its minimal meaning, again accumulates in 5th fraction, then regularly decreases and reaches the minimal meaning in last-distilled fractions. To the same regularity obeys the curves showing the isoamyl and other admixtures quantitative content. There are presented the changes of distilled distillate’s chemical composition during the distillation process of raw alcohol. The analysis of the received fractions’ organoleptic indexes showed that the best quality distillate is received after the taking off the first 35% during the distillate distillation process. The left last distilled fraction should be distilled second time in order to get the additional amount of product fraction. It is known that last distilled fractions consists of big amount of high-fermenting alcohols from C3 to C10 and β-phenylethyl alcohol. This last one gives the rose fragrance to the drink. Thereby it is necessary to distill the last distilled fraction second time and blending of received product fraction to the main product. Existence of diagrams expressing the admixtures compound allows as to choose the rakhi oil’s and methanol’s minimal consisting fractions during the distillates distillation process. With taking into account of chemical composition and organoleptic data it is advisable to remove the 3% of first fraction amount during the distillates distillation, mid-distillate’s outcome is 35%. What about the last distillate fraction it can be distillated second time in order to get the products’ additional amount. The chemical compositions of first, mid and last distilled fractions, which analysis allow us to make the following conclusions and recommendations: 1. During the fractioning of alcohol the highest alcohols main amount distributes in mid and last distillated fractions; 2. Aldehydes (and including acetic acid aldehydes) are concentrated in liquid fraction, in the following fractions their consistence regularly decreases; 3. During the raw alcohol distillation process also big amount of first distillated fraction is presented. Then follows mid-distillated fraction and in last distillated fraction they are not at all; 4. Big part of toxic substance – methanol is in fist distillated fraction, and, accordingly its quantitative content in fraction goods can be decreases to norm during the distillation of raw alcohol, by the regulating the first distillated fractions amount. | technological instruction |
| 1.6/2018 | Investigate the winemaking technology of Kakhetian type young wines | State targeted program | Ministry of education and science of georgia | 0 | 01/01/2017-31/12/2022 | NAna Ebelashvili | Eteri Uturashvili Nino Khvedelidze Mariam Loladze Inessa Kekelidze | The young wines are poured till the January of harvest year. These kinds of wines in France are known as “Beaujolais Nouveau” type wines, demand on them last years greatly increased in Europe and America. For the first time in winemaking practice there was put task about getting the Georgian type young wines from white and red type grapes. | Experiment was conducted in the experimental workshop of the institute. The received wine samples were poured in December of the current year. In the tables 4.2-4.4 are given the results of Kakhetian Green type grape wines researches (one year data). The received data confirms the fact that during the processing of white type grapes with Kakhetian technology (grape juice fermentation on must), like the red type grape – Saperavi, seeds existence in must significantly influences on the quality of young wine, so, during the fermentation on seeds there is received the rough, bitter wine, while wine fermented on must without seeds, as wines received by fermenting on grape juice are characterized with softness and velvety, without any sense of roughness. The analysis of presented data shows that the Kakhetian Green type grape is wonderful raw material to make the high quality young wines to process the grape with European and Kakhetian technology as well. | technological instruction |
| 1.2/2017 | There were investigated the influence of bone-free grapes juice fermentation on the quality of white and red Kakhetian type wines. | State targeted program | Ministry of education and science of georgia | 0 | 01/01/2017-31/12/2023 | Nugzar Baghaturia | Eteri Uturashvili slow gilauri Neli Iluridze Mzia Ichkitidze Mariam Loladze | The phenol compound in grape separate parts differently influence on the wine quality. In particular, tannins of stem and seeds give wine bitterness. Wines fermented on the skin tannin are characterized with softness and velvety. For the first time in winemaking practice there was issued a task to establish the influence of taking seeds away during the fermentation of Kakhetian white and Red wines on the wine quality. | As an object of research there was used the Georgian white industrial type grape – “Rkatsiteli” and “Manavi (Kakhetian) Green” and red type grape – “Saperavi”. On picture 3.1 there are shown the chemical compositions of self-leaked and pressed fractions’ of Rkatsiteli fermented on seed free and seed including must. There was established that the wine fermented on seeds gets roughness the composition of leico-anthocyans and other monomeral phenols. As it is shown from the table data the composition of leico-anthocyans are more in wines fermented on seeds. However, the composition of leico-anthocyasns is so minimal in Rkatsiteli wines that seeds removal from must does not influences on the wine quality. From the data we see that leico-anthocyans are presented more in red wines so these substances noticeably influences on wine quality | technological instruction |

In the institute there are conducted the researches in order to establish the rational technology to process the given secondary raw material. | In 2021 the research on the issues to work out the technology of producing the new products from the tangerine non standard fruits were continued. The research of obtained product’s chemical composition is in process. In 2021 three new products were obtained from the non-standard fruits of tangerine: tangerine distillated oil, tangerine hydrolate and tangerine pasta. There are conducted the works in order to use the pasta in bread and bakery production. | technological instruction |
| 1.1/2017 | Investigation of innovative technologies of Kolkhetian bio wine and bio alcoholic drinks. Investigation of Kolkhetian natural sparkling wine technology. | State targeted program | Ministry of education and science of georgia | 0 | 01/01/2013-31/12/2019 | Nugzar Baghaturia | Nana Begiashvili Inessa Kekelidze Elene Kalatozishvili Mariam Loladze | Last years on the world market there appear more natural sparkling wines that are made with the minimal men interruption during the vinification process. These are unfiltered sparkling wines with sediment. The price of sparkling wines varies between 35-45 USD because the wines are natural. So called Pet-Nat Wines belong to this group of sparkling wines. | It is remarkable that the sparkling wines made by the old Kolkhetian technology have much higher quality than French Pet-Nat ones. So, Georgian winemaking should be developed not to the bio wine direction, but implementing the production of Kolkhetian sparkling wines that will noticeably increase the export possibilities of country. The presented analysis of data show that alcoholic fermentation process is very quick and it is hard to catch the moment when sugar content in it reduces till 15%. Main thing is that on 2nd - 3rd day, when alcohol gets up to 12-13%, red wine does not get on its maximum index. It happens only on 9th – 10th day of alcoholic fermentation, however during the process of Kakhetian white wines as well as red ones it’s advisable to ferment the wine till the end (in Kvevri or ground-over fermentation vessel), fermented wine material should be bottled, grape juice and yeast added, and the wine should be aged there during 2-9 months | Technological instruction |

There are known the 30 varieties of savory, among them in Georgia mostly are spread and used as spice the above ground part of garden savory, ripe savory, mountain savory, . . . . savory in beginning or during the flowing. After drying the raw savory aroma gets stronger. | Savory above ground part consists of different diameter stalks, leaves, buds and flowers. Counted vegetal organs are characterized with the different chemical composition. According to the investigations conducted at the Research Institute of Food Industry in order to grind the dried savory with high quality its humidity should not be more than 8%. Grinded savory is characterized with the hygroscopicity: during the storage it absorbs the moist from environment and its moistness increases up to 10-12%. Savory drying technology includes the preparation for drying, drying, inspection of dried savory, grinding and packaging. In order to establish the optimal conditions for savory drying there were investigated the raw materials cutting influence on the drying kinetic. According to the experiment data cutting of the raw savory helps the equalization and intensification of drying process. Because of the mentioned this process was included into the savory production technological process. Also, cut fraction’s optimal linear size is 50-50 mm, for savory cutting was selected the cutting machine “Rhythm”. | Technological instruction |

The strong tree twigs of juniper make bright forests in the Mediterranean, minor and central Asia, south regions of north America and Mexico, mountain regions of Crimea, Caucasia, middle Asia and Far East. In Caucasus there are spread 7 wildly growing varieties, among them 7 in Georgia – thick-skinned, multiparous plant, Chinese, Savin juniper, Virginian, heavy smell and long needled. Juniper needles and cone-berries main components are vitamin B1, B2, C, PP sugars and essential oil. Especially big amount of vitamin C and PP -126,2 mg. % and 0,0118 mg. % are in juniper needles. Cone-berries consists of about 0,5 – 2,0% of essential oil, 40% of invert sugar, 90% of tar, pectin substances, organic acids and other substances. From the early times juniper needles, fruits and cone-berries extracts are used in folk medicine to cure the inflammatory processes, arthropathy (salt accumulation), rheumatism and skin different diseases, for wound disinfection, diuretic and cough medicines. The chemical composition of juniper cone-berries and needles essential oils (can be said that it is completely studied by some researchers and is established that the mentioned oils may be used in food, pharmaceutical and perfumery – cosmetic industry). For nowadays the wildly growing spread in Georgia varieties of juniper and its raw material are not studied from the view of preparing the food additive essential oil extracts and their usage in food industry. Juniper cone-berries and needles were done in December 2011. In the given raw material, the essential oil consistence was determined with the method of Gimzburg and Dalmatov. During the essential oil distillation process was accumulated the condensate in which there was determined dry substance mass share. From the cone-berries there also was prepared the alcoholic tincture in which also was determined the dry substance mass share. The consistence od the essential oil was determined in crushed and uncrushed cone-berries. | Technological instruction |

Begiashvili L.Kotorashvili T.Nanitashvili N.Alkhanashvili | The sanitary-hygienic evaluation of food products is done according to the common biological values, for that it is necessary to check the validity of food products (should not be polluted, rotted, expired). While evaluating the food products to the account should be taken their organoleptic, chemical and bacteriological indexes. Products of animal origin are characterized with the enough amount content of easily digestible nitrogenous compounds (protein) and fats having high biological values. Many vegetable products are rich of carbohydrates, proteins and fats are low (except walnuts and sunflowers). | With the existing standards and temporary instructions in different branches of food industry are foreseen the product pollution norms with profit microbes, but existence of pathogenic microbes in food products is now allowed. In calculating period are conducted the microbiological investigation on food products: milk and dairy products, meat and meat products, poultry meat, fish and fish products, confectionary. Based on the conducted research results we can conclude the following, as milk, meat, fish and fish products are good soil for the microorganisms’ reproduction and vitality, also belong to the easily spoiling products – must be followed the sanitary-hygienic requirements, as during their production during sale as well to avoid product’s secondary contamination. | Technological instruction |

Each kind of these raw materials are characterized with the big number of varieties, therefore with morphological and physico-chemical indicators varieties. Apple’s industrial kinds are more than 55, and dry substances consistence in them varies from 9,8 to 17,1%. During the drying in order to increase the evaporating surface, provide the equal drying and speed up the process pear fruits are cut into parts (sectors), apple fruits into circles, or parts | Thermochemical processing of apple and pear fruits involves sulfation, for that cut fruit should be soaked for 3-4 minutes in 0,2-0,3% sulfuric acid solution. In farms in case of lack of sulfuric acid this process may be conducted by burning the sulfur in hermetic storage and holding the separated fruit in the generated smoke for 1,5 – 2 hours. In sulfated fruit the remaining amount of sulfur anhydride should not be more than 0,08%; Production of dried apple and pear is allowed without sulfation. In this case, in order to avoid the fermentation darkness, separated fruit from cutting to drying should not be holden more than for 20 minutes. For fruit drying we chose conveyer type 5L dryer, which works as on steam and on diesel as well. These dryers for nowadays are the most mechanized and hygienic, are characterized with high productivity and low energy consumption. Conveyer type dryers are different sizes and productivity. Their productivity changes from 90 kg to 540 kg evaporated humidity an hour. Factory making these dryers makes four different trademark and accordingly different producers dryers that gives the farmers an opportunity to choose the appropriate and price dryers for them. Changes during the fruit drying and mass changing processes and drying kinetics were studied in laboratory conditions on a small size experimental dryer that allowed us to save the raw materials. The dryer was equipped with the controlling – measuring tools; continuous registration of temperature was made by the self-recording electronic potentiometer; as a hear carrier was used the environmental air, which was given by the ventilator to the electric-calorifier, then to the drying camera. Continuous registration of drying raw material allowed us to make drying and temperature curves; as a drying objects were used the different types of apple and kiefer seedling pear fruits. Work out of experiment results were done by making the sorption curves; calculation of balanced humidity was done in percent in relation with the whole mass of product. At the same time with study of sorption features there were conducted systematic visual observation in order to record the development of biochemical processes. The chemical analysis of samples were done after 3, 6 and 8 months; were determined the humidity mass share in samples and sensor indexes. | A technological instruction has been developed |

Gilauri N.Iluridze L.Konjaria | Complication in economic and ecological situation in our country during the last years caused the worsening of some indexes of agricultural raw materials and food products produced from them. One of the global problems of the international organizations is considered the microbiological pollution of food products, it presents the main factor that conditions the health of population. In the population health strengthening system big role is given to the rational nutrition. Human nutrition is one of the environmental factors, which substantially influences on its health, work ability and life length. | In food industry enterprises microorganisms are considered not only as initiator of biochemical processes but also when non-existing microbes develop the food products may become heavy and sometimes the reason of lethal diseases. Diseases like these are related to the using of polluted products. Should be noted that the existence of pathogenic microbes in food products in not the main thing, more important is the existence of determined required conditions necessary for their multiplication. The favorable conditions for nutritional information development are every moment of microbes’ multiplication and accumulation: wrong management of technological processes (as a result of which pathogenic microbe accidentally got into food lives and multiplies), wrong processing regime, creation of food damaging conditions, etc. Sanitary-hygienic evaluation of food products are according the organoleptic, physico-chemical, microbiological and other data, in the most cases decisive role plays the microbiological one. Samples for experiment were bought in supermarkets, markets, fridges and rarely from entrepreneurs. Microbiological examinations were conducted according to the existing standard requirements, also observed on different product analysis in which case using of which standard gives the best results in short period. As a result of conducted analysis revealed that beef, port and chicken’s fresh meet, egg, smoked and frozen fish’s sanitary and microbiological index are satisfied. In sausage products and semi-finished products of grind meat appeared rot and gut group bacteria, staphylococcus, in some cases sulfite-reducing clostridia and salmonellae. The more amount of gut bacteria product contains, the more contaminated it is. In case of massive existence of pathogen bacteria in product microbes can easier pass the body’s protective obstacles and cause disease, foreseeing all abovesaid it is appropriate to conduct the gut bacteria group amount determination in examined samples. We more frequently were determining coli titer, which means that minimal mass or wight of research samples where it was found. For determining the coli titer are used the . . . . . test tubes, in which there is an electric liquid area. We put the research material with proportional reduction in it (or research material’s one milliliter of dissolved solution, previously prepared with the marginal dissolving method). Planted test tubes are placed in thermostat on the temperature at which the gut group bacteria develop well 37±20. We observe for two days but titer is determined according to which minimal amount of put in plant gave fermentation forming acid and air. | Thus, the following can be concluded from the results of the microbiological examination: it is necessary to detect sanitary-indicator microorganisms in perishable food products, which can be done with stricter norms, and it is also necessary to conduct an examination of the rotting bacteria - B. proteus in almost all meat, milk and fish products. |

In both situation the technological process has negative side – environment is polluted with the salt solution and remains. The aim of our research is to investigate the sugar syrup influence on the fermentation process of rose flowers. Abovesaid allows us to receive the rose essential oil and ready product – rose jam at the same time. In case of positive decision there will be avoided the negative side that follows the existing technologies of rose flowers processing. | For the experiment was used the rose “Crimea Red”. At first from the flowers were taken off the stems, bowls and seeds, and from the jam leaves white parts. The last is foreseen by the existing rose jam-making technology. Later in text - rose leaves - mean the leaves from which the white part is separated. After determining the essential oil content in rose leaves the mass left in flask (remainder that was through away before and was polluting the environment) was used by us for preparing the rose jam. Usually, with the existing technology rose jam is boiled in 40% sugar syrup in which, on the last stage is added 0,125% citric acid. Based on the abovesaid in the case when for the fermentation of rose leaves, we used 40% sugar syrup, after determining the oil containing to the mass left in flask was added relevant amount of citric acid; and in the case when for the fermentation of rose leaves, we used 20% sugar syrup, to the mass left in flask was added relevant amount of sugar and citric acid. In both cases after adding the ingredients we boiled the mass (till getting the jam consistence), packed hot and closed hermetically. At the same time beside the abovesaid there was boiled the rose jam with the existing technology. So, during the calculating period there were investigated the physico-chemical indexes of the essential oil received after the fermentation of rose flowers with different methods. On the bases of received analysis results it is established that in order to avoid the worsening of rose essential oil quality index, rose flowers fermented in anaerobic conditions should be processed immediately after fermentation, in case if it is not possible then fermented rose flowers before processing may be kept in clean water not more than 10 hours, because storage for more time increases the oil outcome but makes the oil quality index worse. | An internal standard of the enterprise has been developed |

Begiashvili M. Ormotsadze L. Kotorashvili T. Gejadze | This year, the phenolic compounds, microelements, reduced extract and organic acids of European, Kakhuri and Imerian white table wines were studied. Wine materials were made by classical technology. Natural wines were made as a control option, and 25%, 50%, 75% and 100% adulterated wines were made as a test option for adulteration, which were mainly made by fermenting the sugar solution on chacha. | The content of extracted substances in European-type wines is 18 g/dm3, and the reduced extract is not less than 17 g/dm3, this indicator is above 15 g/dm3 in adulterated samples, and the reduced extract is not less than 14 g/dm3. European wines contain much less phenolic compounds, because they come into contact with chacha during the fermentation process, so their content in natural wine is no less than 300 mg/dm3, catechins - no more than 30 mg/dm3, leucoanthocyanins - no less than 200 mg/dm3. Unlike natural wines, adulterated wines contain total phenols not less than 170 mg/dm3, catechins - not more than 25 mg/dm3 and leucoanthocyanins not less than 180 mg/dm3. In addition to organic acids, total phenols and extractable substances, microelements of wine were also studied to determine naturalness indicators. | Technological instruction |
