Авторами статьи впервые разработана технология производства соков прямого отжима и высокой концентрации из плодов бузины садовой и дикорастущей, собранных на территории Беларуси. Сок прямого отжима получали при помощи ферментации с последующей фильтрацией. Концентрированный сок был получен из сока прямого отжима и экстрагирования выжимок. Для максимального извлечения сока после дробления при ферментативной обработке была использована температура 50 °С в течение 240 мин, количество ферментного препарата составляло 400 см/т. Были исследованы органолептические и физико-химические показатели сока прямого отжима и сока концентрированного: массовая доля сухих веществ, aктивная кислотность (рН), массовая доля пектиновых веществ, cодержание антоцианов, белка, массовая доля органических кислот. Исследованы показатели безопасности продукции, впервые определен состав аминокислот (качество и количество) в концентрированном соке бузины. Установлено, что совокупность физико-химических показателей позволяет отнести сок прямого отжима из бузины к профилактическим напиткам. В состав сока бузины высокой концентрации входят 18 аминокислот в количестве 4,84 г/100 мл. Незаменимых аминокислот выявлено 7 в количестве 1,51 г/100 мл. Также сок суммарно содержит фенолы в соотношении 42,95 мг-экв галловой кислоты/г сухого вещества и большое количество гидролизованных танинов. При этом большинство полифенольных соединений избежали разрушения в процессе концентрации. The authors of the article developed for the first time a technological process for the production of direct-squeezed juice and concentrated juice from the fruits of garden and wild elderberry growing in the Republic of Belarus. Direct-squeezed juice was obtained by fermentation followed by filtration. Concentrated juice was obtained by processing direct-squeezed juice and extracting the marc. For maximum juice extraction after crushing during enzymatic treatment, a temperature of 50 °C was used for 240 min, the dose of the enzyme preparation was 400 cm/t. Direct-squeezed juice and concentrated juice were studied by organoleptic and physicochemical parameters: mass fraction of solids, active acidity (pH), mass fraction of pectin substances, content of anthocyanins, protein, mass fraction of organic acids. The product safety indicators were studied, the qualitative and quantitative composition of amino acids in concentrated elderberry juice was first determined. It has been established that by the combination of physicochemical parameters, direct squeezed juice from elderberry can be considered a preventive drink. The composition of concentrated elderberry juice includes 18 amino acids, in the amount of 4.84 g/100 ml. 7 essential amino acids were detected in the amount of 1.51 g/100 ml. The concentrated juice contained phenols in the quantity of 42.95 mEq gallic acid / gram dry matter and a large number of hydrolyzed tannins. Most polyphenolic compounds were preserved after the juice concentration.

Rising trends in fish filleting are increasing the amount of processing by-products, such as skins of turbot, a flatfish of high commercial value. In line with circular economy principles, we propose the valorization of turbot skins through a two-step process: initial gelatin extraction described for the first time in turbot, followed by hydrolysis of the remaining solids to produce collagen hydrolysates. We assayed several methods for gelatin extraction, finding differences in gelatin properties depending on chemical treatment and temperature. Of all methods, the application of NaOH, sulfuric, and citric acids at 22 °C results in the highest gel strength (177 g), storage and loss moduli, and gel stability. We found no relation between mechanical properties and content of pyrrolidine amino acids, but the best performing gelatin displays higher structural integrity, with less than 30% of the material below 100 kDa. Collagen hydrolysis was more efficient with papain than alcalase, leading to a greater reduction in Mw of the hydrolysates, which contain a higher proportion of essential amino acids than gelatin and show high in vitro anti-hypertensive activity. These results highlight the suitability of turbot skin by-products as a source of gelatin and the potential of collagen hydrolysates as a functional food and feed ingredient.

The content of protein, moisture content and essential amino acids in conventional and genetically modified soybean grain and selected soybean products (soybean pâté, soybean drink, soybean dessert, tofu) was analyzed in this paper. The following comparative analysis of these products has not yet been carried out. No differences were observed in the amino acid profiles of soybeans and soybean products. The presence of essential amino acids was confirmed except for tryptophan. Its absence, however, may be due not to its absence in the raw material, but to its decomposition as a result of the acid hydrolysis of the sample occurring during its preparation for amino acid determination. Regardless of the type of soybean grain, the content of protein, moisture content and essential amino acids was similar (statistically insignificant difference). Thus, the type of raw material did not determine these parameters. There was a significant imbalance in the quantitative composition of essential amino acids in individual soybean products. Only statistically significant variation was found in genetically modified and conventional soybean pâté. Moreover, in each soy product their amount was lower irrespective of the raw material from which they were manufactured. Therefore, the authors indicate the necessity of enriching soybean products with complete protein to increase their nutritional value.

The article presents the technological potential research results of secondary resources formed in the King crab cutting process for food purposes. The authors analyzed waste (cephalothorax and abdomen) obtained from the King crab industrial processing from the North Okhotsk sea subzone and Primorye subzone. They determined the size and mass characteristics of waste. There is the shell, viscera (including liver), gills and abdominals ratio. A man examined the ratio of mineral (shell) and protein (interior and gills) parts of the studied waste experimentally. The research aim was to determine the total chemical composition, amino acid composition of proteins, fatty acid composition of lipids and mineral composition of the combined waste. The authors revealed that the secondary raw materials under the experiment consisted of the protein by 13.37 ± 0.05 %, lipids by 2.68 ± 0.1 %, minerals by 8.33 ± 0.25 % and carbohydrate compounds by 4.22 ± 0.05 %. The experiment determined the essential amino acids sum in the protein part. Valine, leucine and cysteine are limiting. Fatty acids in lipids waste are represented by polyunsaturated fatty acids in significant amounts (42.11 %). Calcium and sodium are overwhelming macronutrients in the waste from the King crab cutting, while iron and zinc are dominating microelements. The research results indicate the high technological value of waste from King crab cutting and the potential of this secondary raw material as a basis for the production of biologically valuable protein and mineral products.

Разработана рецептура белкового модуля для производства биологически активной добавки, способствующей восстановлению функции сердечно-сосудистой системы в постамбулаторный период. Объектом исследований был белок, полученный из овсяной и миндальной муки и сухого обезжиренного молока. Соотношение ингредиентов белкового модуля, сбалансированного по основным эссенциальным аминокислотам, – миндальной и овсяной муки и сухого обезжиренного молока составило 1 : 1,6 : 2,6 соответственно. Определены индекс растворимости белкового модуля – 98,5% и его протеолитическая активность. Установлено, что показатель протеолиза белкового модуля ниже в 1,6 раза по сравнению с аналогичным показателем белка обезжиренного молока, но в 1,2 и 1,5 раза превышает аналогичные показатели белков овсяной и миндальной муки соответственно. Самый высокий показатель протеолиза белковых систем наблюдался в течение первого часа, затем он снижался, что свидетельствует о практически полном расщеплении белка в первый час ферментативного воздействия. Результаты исследований свидетельствуют о возможности использования белкового модуля в составе биологически активной добавки. The formulation of the protein module for the production of a biologically active additive that helps to restore the function of the cardiovascular system in the post-ambulatory period is developed. The protein obtained from oat and almond flour and skimmed milk powder was the object of research. The ratio of the ingredients of the protein module, balanced by the main essential amino acids, – almond and oat flour and skimmed milk powder was 1 : 1,6: 2,6 respectively. Solubility index of protein module is 98,5%. It is established that the indicator of proteolysis protein module below 1,6 times compared to the same indicator of the protein of skimmed milk, but in 1,2 and 1,5 times exceeds that of the protein of oat and almond flour, respectively. The highest indicator of proteolysis of protein systems was observed during the first hour, then it decreased, what demonstrates almost full proteolysis in the first hour of enzymatic influence. The results of the research indicate the possibility of using the protein module as part of a biologically active additive.

Abstract We report for the first time the concentrations of free amino acids in human intestinal biopsies obtained by routinely performed endoscopy. We studied 15 medical patients with no changes of the mucosa and six HIV-infected persons with duodenitis. The mean (and SD) sum of all amino acids, taurine excepted, was 61.9 (5.4) mmol/kg dry weight in duodenal biopsies of HIV-negative subjects (n = 11) and 82.9 (0.6) mmol/kg in colonic specimens: 50% (44%) of the total (minus taurine) consisted of aspartate and glutamate and 14% (12%), of the essential amino acids. The relative amino acid pattern in duodenum and colon differed completely from that for muscle: aspartate was fourfold higher; glutamate, phenylalanine, glycine, valine, leucine, and isoleucine were about twofold higher. In contrast, glutamine amounted only to 4% (duodenum) to 14% (colon) of muscle glutamine. In duodenal biopsies of the HIV-infected persons, we found significantly (P less than 0.01, except glutamine: P less than 0.025) increased concentrations of glutamate (24.1 vs 17 mmol/kg dry weight), ornithine (1.4 vs 0.4), valine (2.2 vs 1.7), and glutamine.
