Introduction. The production of gluten-free food products, including alcohol-free beverages, is an urgent task for Russian food industry. Buckwheat malt has a great raw material potential, because it consists rutin, which can give the final product some useful functional properties. Aromatic raw materials improve the sensory characteristics of beverages and increase their nutritional value. Study objects and methods. Kvass is a traditional Russian bread juice. To prepare gluten-free kvass, we used light and scalding buckwheat malt and water infusions of barberry, juniper, leaves of garden currant, and lemon balm grass. The wort was prepared by infusion and fermented with bottom beer yeast Saflager W-34/70. Then it was blended with infusions of plant materials. Sensory and physical and chemical properties of kvass were determined by standard methods. Antioxidant activity of the beverages was assessed by using DPPH radical scavenging method. Results and discussion. All samples met the state standard requirements for kvass by sensory, physical, and chemical characteristics. The drinks obtained from the scalding malt were well-fermented and achieved better tasting ratings compared to those from the light malt. The control sample, which contained no aromatic raw materials, received the lowest scores for taste and aroma. The kvass blended with infusions of barberry and garden currant had the best results. The infusions increased the shelf life of the kvass from 7 days (control) to 12 (barberry), 14 (juniper), and 16 (currant). All samples of kvass demonstrated antioxidant activity, the beverage with infusion of garden currant leaves showing the best results (≤ 80%). Antiradical activity was established for the samples blended with barberry and currant infusions. Conclusion. light and scalding buckwheat malt can be used to prepare gluten-free kvass. Blending buckwheat kvass with infusions of aromatic raw materials increased the shelf life of the beverages, improved their taste, aroma, and antioxidant activity (except the sample with infusions of juniper), and gave them antiradical properties.

The most important attention is paid to the search of natural antioxidants and their evaluation in medicinal and food raw materials of plant origin. A number of plants, their extracts, food products, and medicinal preparations appear to be the objects of scientific research. Effectiveness and informative character of research, undoubtedly, depend on relevance, sensitivity, and efficiency of the methods chosen. The aim of this work was to develop and validate the postcolumn high-performance liquid chromatography (HPLC)-DPPH method as well as its application in the evaluation of antioxidant activity of known and unknown compounds scavenging free radicals and existing in medicinal plant raw materials. HPLC-separated compounds were identified at the wavelength of 275 nm, and then the mobile phase with analytes flowed through a mixing tee to the reaction coil, where DPPH reagent solution was supplied. The solution flow rate was 0.4 mL/min. The reaction coil was connected with UV/VIS type detector, which measured absorption of flowing solution at the wavelength of 520 nm. It was determined that vitexin rhamnoside, the dominant compound in the leaves of Crataegus monogyna, was not a significant radical scavenger. The most active antioxidant in the leaves and flowers of Crataegus monogyna was chlorogenic acid. The most active antioxidant in Origanum vulgare raw material was rosmarinic acid. Identified analytes in the extracts of Achillea millefolium that possessed radical-scavenging properties were chlorogenic acid, luteolin-7-Oglucoside, rutin, and luteolin.

The main reason for spoilage of berry raw materials is the high water content in it. And in order to increase the shelf life of such raw materials and products based on it, various dehydration methods are used. Osmotic dehydration, considered in this article, is one of the best and suitable methods for increasing the shelf life of berry products, as well as increasing the biological value of the product. This method is preferred relative to other methods of dehydration due to the fact that when it is used in raw materials, more vitamins and minerals are preserved, and the color, aroma and taste of berries are also better preserved. Osmotic dehydration is a process due to the presence of semi-permeable membranes, during which the concentration is balanced. Osmosis takes place during the immersion of fruits in concentrated solutions of osmotically active substances. In such a system, two opposite processes occur: water diffuses from the product into the solution, and the dissolved substance diffuses from the solution into the product. This article discusses the features of the process of osmotic dehydration of blackcurrant berries. Blackcurrant is a promising raw material for processing enterprises. The berry contains a large amount of ascorbic acid, anthocyanins and has a high antioxidant activity. Methods were studied for samples of dried blackcurrant berries (by convection), with preliminary osmotic dehydration with various osmotic agents (sucrose, flower honey), using the following methods: ascorbic acid and antioxidant activity were determined titrimetrically using the Folin-Ciocalteu reagent polyphenols, spectrophotometrically anthocyanins.

Рост числа больных с алиментарно-зависимыми заболеваниями во многих странах делает необходимым расширение ассортимента продуктов для диетического питания. Исследована возможность применения полисахаридов микробного и растительного происхождения в качестве структурообразователей в рецептуре творожного суфле для безглютенового питания. Предложена замена глютенсодержащего сырья – пшеничной муки на полисахариды (ПС) ксантан и гуаран. Объектом исследования были образцы творожного суфле с внесенным ксантаном или гуараном в количестве 0,3; 0,5; 0,7 и 1,0% от массы сырья взамен пшеничной муки. Контролем служил образец суфле из творога, приготовленного по стандартной рецептуре, без замены пшеничной муки ПС. Установлено, что после выпечки консистенция изделий с ксантаном не соответствовала требованиям, предъявляемым к суфле: оно было плотным и не обладало ярко выраженной характерной пористостью. Наивысшую органолептическую оценку получил образец суфле с содержанием 0,3% гуарана со структурой и вкусом, характерными для контрольного образца. Исследованные физико-химические показатели и пищевая и энергетическая ценность разработанного творожного суфле для безглютенового питания сопоставимы с аналогичными показателями контрольного образца. Рассчитано, что при годовом объеме выработки разработанной продукции 35,3 т срок окупаемости составит 0,33 года при рентабельности 50%. The increase in the number of patients with alimentary-dependent diseases in many countries makes it necessary to expand the range of products for dietary nutrition. The possibility of using polysaccharides of microbial and plant origin as structure-forming agents in the formulation curd souffle for gluten-free nutrition has been investigated. Replacement of gluten-containing raw materials – wheat flour with polysaccharides (PS) xanthan and guaran is proposed. The object of the study was samples of cottage cheese souffle with xanthan or guaran added in the amount of 0,3; 0,5; 0,7 and 1,0% of the mass of raw materials instead of wheat flour. The control was a sample of a souffle made of curd prepared according to a standard formulation, without replacing wheat flour with PS. It was found that after baking, the consistency of products with xanthan did not meet the requirements for the souffle: it was dense and did not have a pronounced characteristic porosity. The highest organoleptic rating was given to a souffle sample containing 0,3% guaran, which had the structure and taste characteristic of the control sample. The studied physical and chemical parameters and the nutritional and energy value of the developed curd souffle for gluten-free nutrition are comparable with similar indicators of the control sample. It is calculated that with an annual output of 3,3 tons of developed products, the payback period will be 0,33 years with a profitability of 50%.

Abstract Raw materials requirement is foremost necessary in construction sector. Due to the increase in construction activities, the raw material utilization is also increased, which may lead to depletion of the resources. The usage of M sand also increases day by day. On the other side, waste disposal is posing a major threat to environment and human health. This paper shows the investigation carried out in manufacturing fly ash bricks made by utilizing vermicompost as an alternative material for M sand, the physical and chemical properties of M sand and vermicompost are studied and they seem to be the same. In this study, an attempt is made to check the feasibility of replacement of vermicompost for M sand in brick making. The brick specimens are casted as per the mix proportions and they are tested for strength and durability at the age of 28 days. It has been identified that the vermicompost replacement at 5% and 10%, the compressive strength of the brick is 7.90 and 7.31% respectively, which is found to be nearer to the strength of the control specimen and the water absorption for all the mixes of the brick casted were below 20% as per IS code. Inclusion of vermicompost in the fly ash bricks will tend to reduce the use of M sand.

The article presents the results of studying the qualitative composition and quantitative content of some groups of phenolic compounds in 11 types of medicinal plants growing in the foothills of the North Caucasus, and provides the estimates of the antioxidant activity of extracts from these plants. The qualitative and quantitative content of phenolic compounds was determined using a Kapel-105M capillary electrophoresis system, and the total antioxidant activity of the extracts was measured on a Tsvet Yauza-01-AA device with an amperometric detector. In the studied plant samples, the total content of tannins was determined, eight phenolcarbonic acids were identified and quantified, as well as quercetin and rutin — two of the most important flavonols. The highest total content of phenolcarbonic acids (11,776.2 mg/kg), as well as the highest antioxidant activity were noted in the aqueous extract obtained from Echinacea purpurea (lat. Echinacea angustifolia). The direct relationship between the antioxidant activity of the studied medicinal raw material and the content of phenolic compounds has been experimentally established as follows: the higher is the concentration of phenolic substances, the higher is the antioxidant activity. The results of this study provide new information on the composition and content of phenolic compounds in some types of wild-growing plant raw materials of the North Caucasus and the antioxidant activity of extracts based thereon that will facilitate the use of the studied plants as a potential source of natural antioxidants in the production of functional materials.

This work was carried out to determine the physical and chemical properties of goldenberry fruit (Physalis peruviana L.) grown in Lam Ha and Don Duong of Lam Dong province in Viet Nam. The shelf-life and quality of fruits during storage time at ambient temperature (28±2oC) were also analysed. The analysis results recorded that most of the physical properties of the fruit grown in the two locations (Lam Ha and Don Duong of Lam Dong province, Viet Nam) yielded no significant differences, except the volume, density, hardness and colour of the fruit. The fruit grown in Lam Ha has a lighter colour and yellow intensity (higher a* and C value) than the ones grown in Don Duong, while the fruits are grown in Don Duong are darker (lower L* and higher Ho). In addition to its attractive properties in terms of colour, aroma and taste, they also contain moderate levels of vitamins (C and A), antioxidants (polyphenols), minerals (especially high content of phosphorus) and fibre. Fruit grown in Don Duong had a higher sweetness than those grown in Lam Ha (the ratio of sugar and acid was 2.7 times more). The concentration of bioactive compounds in the goldenberry fruits grown in Lam Ha and Don Duong were almost similar. The shelf-life of goldenberries up to 20 to 22 days at the ambient temperature of about 28±2oC and 75-80% RH but the quality and sensory characteristics of goldenberry raw materials were declined.
