Наведено результати дослiджень з розроблення новiтнiх технологiчних та технiчних рiшень для перероблення баклажанiв. Запропонована технологiя вирiшує проблему рацiонального використання баклажанiв. Завдяки iнфрачервоному сушiнню отримуємо якiсно новий продукт, що дозволяє максимально зберегти поживнi речовини. Пiд час термiчної обробки змiнюються фiзико-хiмiчнi характеристики висушеного матерiалу: густина, теплоємкiсть, пружнiсть, пористiсть, хiмiчний склад та iншi. Тому дослiджено i представлено результати дослiджень властивостей порошкiв з баклажан. Визначеннi органолептичнi, фiзико-хiмiчнi та структурномеханiчнi показники, що дозволяють розрахувати необхiдну кiлькiсть порошку, яку можна вносити в якостi добавки не впливаючи на структурно-механiчнi властивостi готового продукту. Встановлено рацiональнi для вiдновлення регiдратацiї порошкiв з баклажан умови: температура в дiапазонi вiд 45 °С до 60 °С; тривалiсть набрякання 10-15 хв, спiввiдношення порошку та рiдини 1:3 i 1:4. Дослiджено вмiст токсичних елементiв (Свинець, Кадмiй, Миш'як, Мiдь, Цинк) та мiкробiологiчнi показники (мезофiльнi аеробнi, факультативно-анаеробнi, бактерiї кишкових паличок, бактерiї роду Сальмонела). Встановлено вiдповiднiсть вимогам, що висуваються до даного виду сировини та пiдтверджують безпечнiсть розроблених порошкiв з баклажанiв. Встановлено, що розроблений харчовий порошок має низку позитивних якостей, а саме: тривалий термiн зберiгання, не потребує додаткових примiщень для зберiгання, легко вiдновлюється. Завдяки технологiї iнфрачервоного сушiння, що є одним iз методiв консервування баклажанiв, пiдвищується продуктивнiсть технологiчного процесу виготовлення порошкiв. Пояснюється це тим, що за однаковий промiжок часу отримуємо в двiчi бiльше висушеного продукту порiвняно з конвективними методами. Враховуючу поживну цiннiсть баклажанiв, порошки можна використовувати у рiзних комбiнацiях для забезпечення заданих властивостей кiнцевого продукту. Це дозволить скоротити час на приготування страв, розширить асортимент продукцiї функцiонального призначення Ключовi слова: iнфрачервоне сушiння, процес сушiння, овочевi порошки, порошки з баклажанiв, гiдромодуль, коефiцiєнт набрякання, показники безпечностi

Results of conducted experimental studies of the nutritional value of the developed dry soluble gerodietetic product for enteral nutrition are presented. Content of proteins, fats, and carbohydrates (22.8, 11.8, and 56.4 g/100 g of dry product, respectively) was determined and calorific value (422.8 kcal/100 g) and mass fraction of macronutrients in it were calculated (21.5/25.1/53.4 respectively). Their compliance with recommendations of specialists to satisfy nutritional needs of older people, in particular, those with increased physical and neuro-emotional loads, certain dysfunctions, somatic diseases, injuries, and recovering after them were analyzed and determined. Qualitative and quantitative amino acid composition of the product was studied, the rate of its essential and conditionally essential amino acids was calculated on its basis, coefficient of discrepancy of its amino acid composition was found (17.14 %) and biological value of the protein component (82.86 %) was calculated. Experimental studies of the vitamin value of the developed product and its elemental structure were carried out. The dry product has a fairly high content of vitamins (especially ascorbic acid, retinol, thiamine, pyridoxine) and mineral elements (potassium, calcium, phosphorus, magnesium, iron, iodine, selenium). Based on the obtained results, an average level of satisfaction of the daily need for the studied vitamins (on average within 14–41 %), mineral elements (mostly by 10–25 %) from consumption of 100 g of dry product in the prepared liquid state was calculated. The conducted studies have shown high nutritional value, in particular calorific and biological value of the product and conformity of its composition to the needs of the older age groups

This article highlights the problem of functional nutrition in Ukraine. Rationale and need for creating new products with improved properties are substantiated, the list of used natural additives, which are a source of important nutrients, is given. The results of conducted tests confirm the optimization of the chemical composition of new cereal concentrates, improvement of their organoleptic properties, an extension of shelf life, which indicates that the choice of the prescription components is correct and their rational proportion. The nutritional and biological value of Extrapolyvitamix, a new cereal concentrate, enriched with vegetable powders, wheat germ, casein iodide, and raisins, is determined. The investigations of cereal concentrate properties proved that they might be included in a group of functional foods due to changes in chemical composition, which will compensate for the deficiency of nutrients necessary for optimal body functioning after previous diseases. The rational concentrations of functional ingredients that can be used in new products are established. It is proved that the use of vegetable-based milk substitutes will allow the development of new products that meet current market needs. Taking into account global trends and changes in consumer preferences, plans for future studies focuses on creating new products with high biological value using only plant raw materials.

The aim of the article is to study and to generalize technological properties of eggplant powder, produced by infrared drying at temperatures 50-60 ºС. The results of the conducted complex of studies reflect main technological and consumption properties of the received puree that plays an important role at creating new culinary products. So, for studying technological properties of food eggplant powder, there was considered the complex of base functional-technological properties of powder, produced by infrared drying. For finding optimal conditions of rehydration of eggplant powders, there was studied the influence of such technological factors as: swelling ability; liquid; powder ratio; influence of the solvent temperature on renovation; renovation duration; degree of comminution of powders. Main parameters that influence the renovation ability of dried eggplants are investigated and studied in the article. The results of the studies of technological properties of eggplant powders prove their high rehydration properties. It gives a possibility to use powders at producing different culinary products not only for enriching them with functional ingredients, but also for giving them new technological properties. Based on the obtained results, there was elaborated and presented the new technological scheme of using renewed powders in food compositions.

The article covers the quality and safety indicators of sour cream with vegetable oils, in the composition of which blended oil (sunflower oil + linseed oil) is used as a fat phase in the form of a food emulsion stabilized by an emulsifying complex containing sodium caseinate. According to the chemical composition, sour cream with vegetable oils is characterized by an increased content of the mass fraction of proteins by 0.2% and a reduced content of the mass fraction of carbohydrates by 1.7% compared to classic sour cream, which is connected with the use of food emulsion in its composition. Due to the content of food emulsion, sour cream with vegetable oils has the content of polyunsaturated fatty acids increased by 24 times and the content of saturated and monounsaturated fatty acids decreased by 82.11% and 41.2%, respectively, compared to classic sour cream. The indicator of water activity in sour cream with vegetable oils is 0.983 aw, which is lower than classic sour cream (0.988 aw). According to the results of the study of microbiological parameters, on the fifth day of storage in sour cream with vegetable oils, the titrated acidity index was 86 °Т, the number of lactic acid bacteria was 107 CFU/g, and no bacteria of the Escherichia coli group, mould and yeast were detected; it corresponds to the normalized indicators as for classic sour cream. At the end of the storage period, the value of syneresis in sour cream with vegetable oils is 23% lower than the value of syneresis in the control sample. In sour cream with vegetable oils, during five days of storage, the value of peroxide 3.0 – 4.0 ½ O mmol/k and acid value 2.5 – 2.6 mg acid number/g are within the normalized values for blended oil (sunflower oil + linseed oil).
