The object of research in this work is the technology of pastille with the addition of multicomponent fruit and berry paste. Pastille are becoming more and more popular in the world for all segments of the population. Usually, the main ingredients for their manufacture are fruit raw materials, a structurant and egg white, therefore, the products contain practically no fat and have a low calorie content. It is proposed to replace 75 % of traditional applesauce in the recipe with a multicomponent fruit and berry paste made from apples, cranberries, hawthorn. It was found that such a composition makes it possible to obtain products with an increased content of pectin substances, ascorbic acid, polyphenols, including anthocyanins, catechins and flavonols. The work is aimed at studying the application of the principles of qualimetry to determine a complex indicator of the quality of pastille For this, the organoleptic and physicochemical indicators of the quality of the developed pastille were taken from previous studies and the chemical composition was determined and the content of biologically active substances was calculated relative to the average daily human need. The content of pectin substances in new products increases 1.7 times and satisfies the average daily human need by 18.2 %. The content of ascorbic acid is 4.2 times higher, which is 20.5 % of the average daily human need, and polyphenols 3.2 times higher – 579.0 %. The data obtained make it possible to consider the developed product functional. The next step was to determine the complex indicator of products by the qualimetric method. For a more complete disclosure of product properties, a structure of pastille quality indicators has been developed – a «tree of properties». Thus, the comprehensive assessment of the quality of the control sample corresponds to the indicator «good» (0.66), while the integrated assessment of pastille with multicomponent paste corresponds to the indicator «very good» (0.98). On the basis of organoleptic, physicochemical indicators and chemical composition of products, it was established that the indicator of a comprehensive assessment of the quality of a pastille with a multicomponent paste, taking into account all group indicators, is 48 % higher compared to the control.

Agaricus bisporus is a rich source of biologically active compounds with functional properties that have a positive effect on human health. White and brown A. bisporus mushrooms were grown both organically and conventionally. This study aimed to analyze chemical composition of the mushrooms, their electrochemical properties, and the composition of volatile compounds. The relationships between cultivation practices and the basic chemical composition, electrochemical properties, and aroma compounds of A. bisporus were examined. The results reveal that ecologically grown mushrooms accumulated higher amounts of ascorbic acid while conventionally grown mushrooms accumulated more crude protein and zinc. More substantial amounts of dry matter, crude protein, and crude ash were found in the brown mushrooms. The white mushrooms had a higher content of ascorbic acid, crude fat, and dietary fiber. Ten volatile compounds were tentatively identified in analyzed mushrooms, including five aldehydes, two esters, two alcohols, and one terpene. Conventionally grown mushrooms had a higher pH value, but eco mushrooms had significantly lower redox potential. White mushrooms had lower p-values than brown mushrooms. Eco mushrooms could not be distinguished by their qualitative characteristics. The chemical composition of white and brown mushrooms was somewhat different, and only the electrochemical properties of mushrooms differed significantly.

The purpose of this research is to substantiate and develop the technology of vegetarian cold snacks “VegoShuba”. The object of the study is the technology of salad with the addition of nori leaves, Adyghe cheese, sour cream, asafetida and dried fruits “VegoShuba”. The article substantiates the expediency of using nori leaves, Adyghe cheese, vegetarian mayonnaise, chia seeds, asafetida and dried fruits (prunes and dried apricots) in the technology of vegetarian salad “VegoShuba”. On the basis of technological developments the technology of vegetarian salad “VegoShuba” is developed. The paper presents the results of research on quality indicators and calculates the chemical composition of the developed dish. During technological tests in the prototypes, herring was replaced with nori leaves, eggs – with Adygea cheese, mayonnaise – with sour cream with turmeric and black salt. The optimal amount of chia seeds, Adyghe cheese, asafetida and dried fruits was determined by organoleptic evaluation. After a study of organoleptic characteristics, it was determined that the highest organoleptic evaluation was obtained by experiment with the addition of chia seeds – 0.2 g, asafetida – 0.2 g, prunes – 3 g and dried apricots – 3 g. Analyzing the chemical composition of the vegetarian analogue of the classic dish “Herring under a fur coat” it is possible to observe considerable increase in the content of nutrients. Based on the analysis of the daily nutrient requirements of VegoShuba salad, there is an increase in the satisfaction of daily nutrient requirements, with the exception of vitamin B12. This dish can be recommended in the appropriate restaurants. Taking into account the research and calculations, a model of the quality of the developed dish was built, it reflects the percentage of nutrients in salads to the daily intake. Summarizing the results, we can conclude that the developed dish “VegoShuba” using nori leaves, Adyghe cheese, sour cream, chia seeds, asafetida and dried fruits in certain quantities have compared to the control sample increased biological value due to the variety of ingredients that have composition of biologically active substances and valuable nutrients, so it is a worthy alternative in vegetarian cuisine. The developed dish “VegoShuba” can be recommended for implementation in restaurants of Ukraine.

The fruits of wild rose (Fructus Rosae) have been widely used in both traditional and officinal medicine for the long time. The pharmacological effect of the Rosehip medicine is related to the content of such biologically active compounds as: water-soluble (ascorbic acid) and fat-soluble (carotenoids) vitamins, as well as flavonoids (astragalin, isoquercitrin, tiliroside). Such medicine as Holosas, Carotolin and Rosehip syrup are obtained from the fruits of this plant. In addition, wild rose fruits are part of the various fees from which patients could prepare water infusions at home themselves. Regulatory documentation provides for the analysis of Rosehip raw materials three parameters: the content of ascorbic acid, the total carotenoids and flavonoids. The quantitative content of the total carotenoids in the fruits of the rosehip is regulated for the production of rosehip oil and Carotolin. However, in our opinion, the method of quantitative determination of the total carotenoids, described in the State Pharmacopoeia of the Russian Federation of the XIV edition, is too complicated and contains an unreasonably entered coefficient in the formula, leading to an overestimation of the analysis results in 10 times. We have developed the methodic of quantitative determination of the total carotenoids in Rosehip, that include single extraction of raw materials with hexane at room temperature and periodic mixing in the ratio of «raw material : extract» 1 : 30. Investigated solution there was obtained by diluting the hexane extract in the ratio of 2:25 and measured the optical density at wavelength 450 nm. Adjustments have been made to the formula for the calculating of the total carotenoids relating to the removal of the coefficient 10 unjustifiably entered into the pharmacopoeial methodic. It was determined that the content of the total carotenoids calculated on ß-carotene varied from 10.15 to 74.5 mg%. The metrological characteristics of the methodic indicate that the error of a single determination of the total carotenoids in the rosehip fruits with a 95% confidence level is ± 3.57%. Based on the results of the studies, a new test quality indicators “content of the total carotenoids at least 30 mg%” was substantiated instead of 300 mg%.

The article highlights the research aimed at proving the prospects of using valuable local raw materials – sweet potatoes to increase the nutritional and biological value, as well as reducing the caloric content of flour products from cake dough. The range of flour confectionery products and the peculiarity of manufacturing technology are analyzed. Cake flour products occupy a significant place in the general structure in terms of production, although the analysis of their physical and chemical composition gives grounds to claim that they do not always have a high degree of nutritional and biological value, balanced chemical composition. This is due to the high proportion of carbohydrates, fats and low content of proteins, vitamins and other biologically active compounds. In addition to nutritional value, the shelf life of products is an important factor. Cake products belong to the fat-containing flour confectionery products, and accordingly they are subjected to oxidative treatment, which encourages the search for new antioxidants of natural origin. The aim of the work is to improve the technology of cake batter with the use of sweet potato puree and to study the influence of additives of local plant raw materials on the structural-mechanical and organoleptic characteristics of finished products. The local raw material of sweet potatoes, which is characterized by a valuable chemical composition as a source of vitamins, micro- and macroelements of pectin and dyes, was chosen as an improver. The main indicators of the quality of sweet potato puree were determined experimentally. The influence of sweet potato puree on the organoleptic characteristics of the finished products was investigated, and it was found that the introduction of 20 % puree by weight of flour is optimal. As the concentration of the puree increases, the taste of the product deteriorates, as well as the porosity decreases and the color changes. The positive effect of sweet potato puree on physico-chemical indicators of the quality of finished products has been established. When adding puree in the amount of 20 % by weight of flour, the porosity is increased by 8 % in comparison with the control sample. The technology of obtaining a cake from sweet potato puree has been developed. The prescription composition and the basic technological scheme of their production are substantiated. It is proved that flour products with the addition of sweet potato puree in the amount of 20 % to the weight of the flour are slower to harden and retain their properties for 9 days of storage. The safety of prolonged storage has been confirmed by microbiological studies. Thus, the expediency of using sweet potato puree in the technology of cake dough products in order to reduce calories, increase the biological value, improve organoleptic characteristics. As well as the possibility of replacing artificial improvers in the structure, taste and aroma of cakes, due to the substances contained in sweet potato puree.

Introduction. Currently, close attention in the field of pharmacy and medicine is directed to the search for new sources of biologically active substances of various origins, including vegetable. The woody plant Elaeagnus argentea is considered as a promising source. Despite its widespread use in the food industry, folk medicine as an anti-inflammatory, restorative, antimicrobial agent, the chemical composition of this plant has not been sufficiently studied.Aim. Qualitative and quantitative determination of the main groups of biologically active substances (BAS) in the raw material (leaves) of Elaeagnus argentea growing on the territory of the Astrakhan region for further development of a methodology for standardizing the raw material of this plant.Materials and methods. The leaves of Elaeagnus argentea were harvested in the spring in the eastern part of the delta of the Astrakhan region (Volga region). Drying of raw materials was carried out in natural conditions. In the study, unified methods were used: to determine the amount of flavonoids and saponins, the spectrophotometric method was used, ascorbic acid - the titrimetric method. For the analysis of flavonoids in the leaves of Elaeagnus argentea, an aqueous-alcoholic solution of 70 % concentration was used as an extractant. The quantitative content of flavonoids was determined in the obtained raw material extract in terms of luteolin-7-glucoside. The amount of saponins in the leaves of Elaeagnus argentea was determined in terms of oleanolic acid. 96 % ethanol was used as an extractant. The quantitative determination of ascorbic acid in the aqueous extract of crushed raw materials was carried out by titrimetry based on the ability to reduce 2,6-dichlorophenolindophenol.Results and discussion. In the pharmacognostic study of biologically active substances in the leaves of Elaeagnus argentea, the content of ascorbic acid was found to be at least 0.32 %, the amount of flavonoids in terms of luteolin-7-glucoside was at least 1.92 %; saponins - 2.38 %; which indicates the need for a more detailed study of the phytochemical composition of other morphological groups of the plant Elaeagnus argentea growing in the Astrakhan region.Conclusion. The data obtained during the study can be used to confirm the quality of raw materials (leaves) of Elaeagnus argentea. A more detailed study of leaves for the presence of other groups of biologically active substances will make it possible to use the obtained data for the development of regulatory documents for medicinal plant raw materials «Elaeagnus argentea leaves».
