The article presents data on the development of a new fermented milk product kefir from unconventional milk raw materials of goat’s milk and with the addition of blackberry vegetable additive. It is scientifically justified to use blackberry puree in the production technology, as well as the use of an unconventional type of milk for the manufacture of kefir. The influence of blackberries on the quality indicators of the developed kefir was also investigated. Comparative analysis of kefir with different concentrations of blackberries was carried out. According to the results of organoleptic evaluation, it was revealed that the consistency in all samples is uniform, without disturbing the clot. The taste is sour milk, slightly sharp, without extraneous flavors and odors. There is a good slightly sweet blackberry taste and smell with an increase in the concentration of the additive. It can also be noted from the results that kefir with blackberries is enriched with iron and other micro and macro elements in the comparison with the control sample. According to physicochemical indicators, the sample with 10% replacement of milk with mashed potatoes was identified as the closest to the control. The benefit of goat’s milk kefir is due to the presence of various substances necessary for life. The properties of raw materials used are preserved and even enhanced considering the use of fermentation. Such kefir has a lot of natural proteins, the product is easily digested and absorbed by the body. Goat’s kefir makes it possible to improve digestion and metabolic processes in regular consumption. This product reduces the risk of developing most intestinal infections because of rich composition. There are probiotics in such kefir that oppose the spread of harmful microflora in the intestine. The product includes potassium and magnesium minerals that are especially important for normal operation of heart and vessels. There is phosphorus and calcium in it.

The aim of this study was to determine the effect of adding calcium compounds to processed goat’s milk, and on the properties of acid rennet goat’s milk gels, which are a middle product obtained in the manufacture of acid rennet cheese. The properties of the gels directly affect the quality of acid rennet cheeses. The analysis of raw goat’s milk was carried out, then acid rennet gels were produced with the addition of six different calcium compounds (chloride, citrate, bisglycinate, gluconate, lactate, and carbonate). The dynamics of milk fermentation were performed by monitoring the pH value of milk during acidification. The pH, syneresis, color, and texture profile were determined in the formulated acid rennet gels. An organoleptic evaluation was also performed. The study demonstrated that, not only calcium chloride, but also calcium citrate, gluconate, lactate, bisglycinate, and calcium carbonate could be used in the production of goat’s milk acid rennet gels, or the middle product in the manufacture of acid rennet curd cheese from goat’s milk. Notably, the addition of citrate, bisglycinate, and calcium carbonate in doses of 20 mg Ca 100 g−1 most effectively reduced syneresis compared to the control sample by 4.76% (citrate), 7.85% (bisglycinate), and 10.28% (carbonate). The hardness of the control gels ranged from 2.35 N to 2.99 N. The addition of chloride, citrate, gluconate, lactate, and calcium carbonate to the milk improved the acid rennet gel’s hardness. The addition of 20 mg Ca 100 g−1 as gluconate increased the hardness the most (3.61 N). When increasing the calcium dosage in the form of all compounds, there was a tendency to increase the gel’s springiness. The addition of chloride, citrate, and bisglycinate to milk did not result in a darkening of the gel’s color. The addition of calcium compounds mostly reduced the intensity of goatish taste and odor. Calcium gluconate, in particular, reduced the goatish taste the most, a taste which is not always acceptable by the consumers.

Abstract The inclusion of polysaccharide thickeners in the recipes of sweet dishes increases the functional reserves of the body, contributes to the preservation of health and the prevention of diseases. The purpose of the research is to study the sensory characteristics of polysaccharides of various nature when combined with food acids, to develop a recipe for a basic mixture of low-calorie meals for public catering. The authors analyzed citric, lactic and succinic acids in combinations with polysaccharides of various nature. Organoleptic tests were evaluated by a touch panel. The organization of the tasting analysis corresponded to GOST ISO 6658-2016; the consistency was determined according to GOST 31986-2012, GOST ISO 11036-2017, GOST ISO 8588-2011. The optimal organoleptic combinations of the presented food acids and complex additives of sweeteners (CDP) were identified, which included aspartame, sodium saccharinate, Sucralose, sweetness coefficient – 340: the mixture with citric acid had a long pleasant aftertaste without foreign tastes and the best taste characteristics. Using the “A-not A” method, we found that the sample with the addition of CDP is identical to the sucrose solution. In the second part of the study, polysaccharides were added to model samples of acids with complex sweeteners; the best sensory characteristics were obtained by model samples consisting of a mixture of low-esterified Apple pectin with lactic acid and KDP. The technology of obtaining a stable elastic jelly using low-esterified Apple pectin has been developed, since the complex mixture of sweeteners and food acids does not have a dehydrating effect. Developed a dry mix recipe that can serve as a basic development, low-calorie sweet products for catering and has a variance of use of lactic and succinic acids, depending on the flavor characteristics of the raw materials used and its corrective ability.

The article considers the principle of developing a list of descriptors to describe the sensory characteristics of processed fruit and berry products as a result of osmotic dehydration with hypertonic sucrose solution. The analytical method of organoleptic analysis - the quantitative descriptive method, was used to determine significant characteristics. Initially, the testers compiled a preliminary list of descriptors for processed products, including 54 characteristics, which are divided into groups: consistency, appearance, taste, color and aroma. After deleting synonyms, antonyms, and hedonic descriptors, there are 12 descriptive characteristics left in the list. The following descriptors were identified: integrity of form, gloss, brightness of color, consistency: dense, juicy, soft, tender, watery, chewable, sticky, taste: pronounced varietal, sweet and sour taste, intense and extraneous aroma. After discussion between the testers and the head of research for unambiguous understanding of the descriptive characteristics was carried out studies of samples of berry, fruit products and structured reference profilograms frozen and frozen sweet berries and dried reference and dried fruit production. As a result of the organoleptic evaluation, it was found that all processed berries and fruits have a well-preserved consistency, appearance, taste, aroma and color. Levels of density, richness was appreciated, preserved the integrity of the form, pronounced colouring, no foreign flavor, taste of berries meets the variety, berries are delicate compared to a control sample. Thus the organoleptic quality assessment of processed fruit products showed that pre-osmotic dehydration with sucrose solutions for further processes such as freezing and drying have allowed for some handles to protect the structure of fruit and berry raw materials and does not negatively affect the indicators of appearance, consistency, taste, color and aroma, and improved their quality compared to traditional frozen or dried fruit and berry production.

Abstract Lonicera caerulea L., also known as honeysuckle berries, are rich in biologically active compounds, which makes them a valuable raw material for the development of functional foods. The objects of the research were three honeysuckle cultivars (‘Zoluška’, ‘Siņaja Ptica’, ‘Goluboje Vereteno’), four genotypes (No 2A; No 3; No 5; No 8) and kefir, enriched with various amounts (3–10%) of fruit puree. Physical and chemical analyses to determine the qualitative indicators of raw materials and products were performed. The degree of liking of kefir was assessed using sensory analysis: hedonic and line scales. The results obtained showed that among the cultivars the highest content of anthocyanins (1103.5 mg·100 g−1), total phenols (693.3 mg·100 g−1), flavonoids (753.9 mg·100 g−1), and tannins (1.6 mg·100 g−1), were found in ‘Siņaja Ptica’ berries, while among the genotypes, berries of No 8 had the highest concentration of the aforesaid compounds. Both samples also showed the highest antiradical activity: ABTS+• on average by 71.7% and DPPH− by 43.7%. According to the sensory evaluation, kefir with 10% honeysuckle puree was rated the highest. Honeysuckle berries could be used as a promising source of natural anti-oxidants in future research aimed at developing different new products that could meet consumer expectations.

The results of the study of the natural sweetener effect from Stevia on the quality of two types of table semisweet fruit blended wine - from gooseberries and raspberries, gooseberries and black currants - in comparison with the classical recipe with sugar, are presented in the article. The recipes and the production technology of table blended fruit wine with Stevia extract as a sweetener were presented in the work. Stevia extract and sugar (control sample) were added after complete fermentation of sugars into dry wine material. The extract dose was 1.4 ml per 1 liter of wine material. Organoleptic and tasting evaluation of the finished product showed that wine with the addition of Stevia extract has good quality indicators, a pleasant taste without extraneous smacks. The sugar content was practically at zero point - 0.25 g / l in wine from gooseberries and raspberries, 0.28 g / l in wine from gooseberries and black currants. In the wine made by classical technology, the sugar content was 70.30 g / l and 71.10 g / l, respectively. The titrated acidity of the wine was within the requirements of the regulatory document and ranged from 9.0 to 10.9 g / dm3. The content of vitamin C and beta-carotene depended to a greater extent on the type of fruit and berry raw materials used. A higher content of ascorbic acid was noted in blended wine from gooseberries and black currants - at the level of 26.88–27.02 mg, beta-carotene - in wine from gooseberries and raspberries. The introduction of sugar or Stevia extract did not affect the values of these indicators much. According to the results of studies in the manufacture of blended fruit wines in order to reduce their calorie content and use as a functional product, the addition of Stevia extract is recommended

The formulations of sour-milk products made by the thermostat method with the use of protein concentrates are developed. The classic technology of thermosetting is used as a basis, with preliminary preparation of mixtures based on normalized milk, milk protein concentrate (KMBS-65) and serum protein ultra filtration concentrate (KSB-UV-65), followed by pasteurization and suction. Concentrates used in dry form. Milk protein promotes nutrition of tissues not short-lived, but in the long-term, which is very important for intense physical activity, and high intellectual activity. Whey protein is rapidly absorbed and the nutrients that it carries with them, in short time, enter the tissues of the body, including muscle. This allows you to compensate for energy costs in a short time and improve the processes of exchange designed to normalize the work of organs and systems. Protein concentrates are used to improve the density of the bunch and reduce the degree of syneresis. The product is enriched with a concentrate and will act as an additional source of natural milk protein supplementation to the human body. The optimum component composition of the mixture – the sour milk product, using model milk samples and protein concentrates containing 3; 5; 7; 10% of total volume. Control sample, without protein concentrate. In the preparation of mixtures, the optimal temperature for the administration of protein concentrates was determined by a practical method.
