Від 2011 року кафедра має назву "Технологія жирів і продуктів бродіння", первісна назва – "Технологія жирів".

Кафедра "Технологія жирів" розпочала свою діяльність у 1930 році. Від початку заснування ХПТІ, спеціальність технологія жирів була складовою частиною кафедри технології органічних і забарвлюючих речовин і тільки в 1923 році виділена в окрему групу.

Кафедра входить до складу Навчально-наукового інституту хімічних технологій та інженерії Національного технічного університету "Харківський політехнічний інститут". Випускники кафедри працюють в олійно-жировій, кондитерській, пивоварній, виноробній, спиртовій, лікеро-горілчаній та безалкогольній галузях харчової промисловості.

У складі науково-педагогічного колективу кафедри працюють: 3 доктора та 10 кандидатів технічних наук; 3 співробітника мають звання професора, 4 – доцента, 1 – старшого наукового співробітника.

    Modelling formulae of strawberry whey drinks of prophylactic application
    (Одеська національна академія харчових технологій, 2017) Tkachenko, N.; Nekrasov, P. O. ; Vikul, S.; Honcharuk, Ya.
    Expediency of the development of formulae and innovative technologies for production of prophylactic application drinks possessing antioxidant, probiotic and hepatoprotective properties with the use of the secondary dairy product – whey, as well as the domestic vegetable raw materials having a high content of bioactive substances has been substantiated. Formulation composition of the prophylactic drinks based on cheese whey, extract of Tagetes patula flowers and the berry filler “Strawberry” with the use of the response surface method has been developed. Bioactivity of the drinks and the complex quality indicator which accounts for the total influence of the bioactivity, organoleptic assessment and weight coefficients of the specified unit indicators were taken as the optimization criteria; as the independent factors that were varied in the course of the experiment, the mass fractions of the marigold flowers extract and the strawberries filler were selected. It is recommended that the mass fractions of the berry filler “Strawberry” and the extract of Tagetes patula flowers in the prophylactic drinks are set as 7 and 20 % of the finished product, accordingly. The practical mass fraction of the citric acid of 0.2 % was determined as it ensures high organoleptic characteristics of the finished drinks. Recommendations are given concerning development of innovative technologies of unfermented and fermented strawberry whey drinks of prophylactic application enriched with the extract of Tagetes patula flowers.

    Substantiation of storage parameters of the sour-milk infant drink "Biolakt"
    (Одеська національна академія харчових технологій, 2017) Tkachenko, N.; Nekrasov, P. O. ; Avershina, A.; Ukrainceva, Ju.
    Changes in the quality indicators of sour-milk infant drink «Biolakt» characterized by high probiotic and immunomodulatory properties and low allergic effect that were made according to the improved technology and stored in sealed-off containers at temperature (4±2) ºС during 28 days have been studied: organoleptic properties of taste and odour, consistency and appearance; physical and chemical properties – titrated acidity, ºТ; active acidity, pH units; moisture retention property, %; microbiological properties – number of living cells of mixed cultures B. bifidum 1 + B. longum Ya3 + B. infantis 512, CFU/cm³; the most probable number of living cells of monocultures L. acidophilus La-5, CFU/cm³; presence of coli form bacteria in 0.3 cm³; presence of Salmonella in 50 cm3; biochemical properties – antioxidant activity, activity units; and maximum possible content of malondialdehyde at complete oxidation of the product ingredients, mg/100 g. It is proved that under indicated conditions in the course of 24 days the studied samples of target products possess high organoleptic and standardized for sour-milk infant drinks physical, chemical, biochemical and microbiological indicators and are, also, characterized by high content of probiotics: (0.43 – 8.60)∙109 and (0.25 – 1.10)∙109 CFU/cm3 of living cells of bifidus bacteria and lactobacilli, accordingly. It has been established that the limit storage period of sour-milk infant drink «Biolakt» produced according to the improved technology and stored at temperature (4±2) ºС should not exceed 12 days with due account of the safety margin for sour-milk infant drinks (provided they are kept in sealed-off containers). It has been proved that the target product formulas should include lactulose, polyunsaturated fatty acids omega-3 FT EU of «Fortitech» company (Denmark), vitamin complex FT 041081EU of «Fortitech» company (Denmark) and/or complex of mineral substances FT 042836EU of «Fortitech» company (Denmark).

    Optimization of formulation composition of the low-calorie emulsion fat systems
    (Технологический центр, 2016) Tkachenko, N.; Nekrasov, P. O. ; Makovska, T.; Lanzhenko, L.
    Among the promising food products of oil-and-fat industry, special place is held by emulsion fat products, in which vegetable oil is in the dispersed state that increases its assimilation. High taste and nutritional properties, due to the specific character of their structure, are inherent in emulsion fat systems. Therefore, water-fat emulsions are the promising systems, on the basis of which it is possible to create mayonnaises, sauces, dressings, oil pastes, spreads and other food products, including low fat ones, with the balanced composition and health-improving properties. The work substantiated the optimum content of the concentrate of Jerusalem artichoke “Noteo” and the stabilizing system “Hamulsion QNA» – 10,06 and 0,42 % respectively, as the components of low calorie emulsion fat basis for the production of low fat oil-and-fat products. It is shown that a low calorie emulsion fat system, produced with the use of raw components in the optimal ratio, possesses standardized physical-chemical and microbiological indicators, high organoleptic characteristics and can be used as the raw material for the production of low calorie mayonnaises, sauces and dressings for healthy nutrition. The recommendations are provided regarding the design of the technologies of the two groups of low calorie mayonnaises, sauces, dressings, enriched with food fibers and prebiotics (or the complexes of synbiotics), on the basis of the developed emulsion fat systems.
