Проведена сравнительная оценка хлебопекарных смесей (ХПС) Ливенка и Амарантус, включающих биоактивированное зерно пшеницы и ржи и биоактивированные злаковые культуры и амарантовую муку соответственно, и хлеба на их основе. Исследованы химический состав, биологическая и энергетическая ценность ХПС и выпеченных на их основе образцов зернового хлеба Ливенский и Амарантус. Установлено, что ХПС Амарантус и хлеб Амарантус отличаются несколько большим содержанием белка, кальция, лизина по сравнению с ХПС Ливенка и хлебом Ливенский. Однако по количеству пищевых волокон и витаминов ХПС с амарантовой мукой и изделия на ее основе несколько уступают образцам, приготовленным без добавки амарантовой муки. Внесение амарантовой муки в дозировке 5,5% взамен части ржаной муки незначительно повышает энергетическую и биологическую ценность ХПС и хлеба на ее основе. Установлено, что ХПС Ливенка и Амарантус относятся к функциональным пищевым ингредиентам за счет содержания значимого количества биологически активных веществ, а изделия на их основе – к функциональным пищевым продуктам. Comparative evaluation of baking mixes (BM) of Livenka and Amarantus, including bioactivated grains of wheat and rye and bioactivated cereals and amaranth flour, respectively, and bread on their basis was carried out. Chemical composition, biological and energy value of BM and baked on their basis samples of grain bread Livenskiy and Amarantus were investigated. It is established that the BM Amarantus and bread Amarantus are slightly high content of protein, calcium, lysine, compared with BM Livenka and bread Livenskiy. However, the number of dietary fibers and vitamins BM with amaranth flour and products on it based are concede to samples a little prepared without the addition of amaranth flour. The introduction of amaranth flour in a dosage of 5,5% instead of a portion of rye flour slightly increases the energy and biological value of BM and bread on it based. It was found that the BM Livenka and Amarantus are functional food ingredients due to the content of a significant amount of biologically active substances, and products on their based – to functional foods.

Introduction. With the development of the food and processing industry, the matter of environmental pollution is becoming more and more acute. Environmental protection is based on the principle of rational use of natural resources and sustainable technology. Vegetable pomace is a secondary raw material; its amount depends on the production technology and equipment. The observed positive trend in the gross harvest of vegetables in open ground can increase the number of vegetable processing enterprises and the capacity of existing enterprises. Eventually, waste will start accumulating at processing sites, and it will have to be used as raw materials. The present paper features the content of biologically active substances in pomace of carrots and beets grown on the territory of the Siberian region and introduces options for their further use in functional foods. Study objects and methods. The research featured carrot pomace of the varieties Losinoostrovskaya, Nantskaya, and Queen of Autumn, as well as beet pomace of varieties Cylinder and Bordeaux. All the samples were harvested in the Kemerovo region in 2019. Determination of physical and chemical parameters was carried out using standard methods. Carotenoids, flavonoids, β-cyanine were studied using spectrometry and photocolorimetric method. Results and discussion. The experiment featured the content of bioactive substances in pomace of carrots and beets obtained during industrial processing. The content of carotenoids in carrots (mg of β-carotene per 100 g of dry weight): for Losinoostrovskaya variety – 23.56 ± 0.23; Nantskaya – 25.32 ± 0.18; Queen of Autumn – 20.78 ± 0.25. Flavonoid content (mg of catechol equivalent per 100 g of dry weight): Losinoostrovskaya – 12.02 ± 0.37; Nantskaya – 13.45 ± 0.56; Queen of Autumn – 11.50 ± 0.48. The content of β-cyanine in beets (mg per 100 g of dry weight): Cylinder – 100.0 ± 8.5; Bordeaux – 35.0 ± 1.8. The nutritional value of carrot and beet pomace with a mass fraction of moisture was 10%. The nutritional value of vegetable pomace is due to the high content of dietary fiber; therefore, the raw materials can be considered for functional food production. The content of biologically active substances in vegetable pomace (flavonoids, carotenoids, β-cyanines) can enhance the functional orientation of this secondary raw material when used in food technologies for the production of food of high nutritional value. Conclusion. The results obtained will make it possible to use the biochemical potential of plant raw materials in many aspects, as well as to obtain new functional food products, thereby expanding the range of healthy foods.

The aim of study is reduction of accumulation of heavy metals in agrocenosis of pulse crops due to the action of biologically active substances in the conditions of the middle Volga forest. An experiment study in order to reveal the effect of pre-sowing seed treatment with biologically active substances on the accumulation of heavy metals by soils and plants in agrocenoses of peas and soybeans was conducted in 2013-2015. The results of pre – sowing treatment of soybean seeds of the Samer 3 breed and peas of the Flagman 12 with the Rizotorfin and Rizotorfin in combination with analogues – Agrica and Humariz biologically active substance are presented. The analysis of heavy metals content in soil and plant samples was performed in the laboratory of the «Samara agrochemical ser-vice» Station by method of atomic adsorption spectroscopy. It is established that the introduction of biologically ac-tive substances into the soil containing heavy metals can reduce the concentration of their mobile forms and restrict access to grain. The content of mobile forms of elements in the soil under soybean growing areas, in comparison with the control, decreases: lead by 1.14 times when treated with Rhizotorphin+Humariz, cadmium – 1.18 times when treated with Rhizotorphin, copper – 1.2 times and cobalt – 2.0 times under the influence of the combination of Rhizotorphin and Agrica. According to the coefficients of biological absorption of pea and soy grains, the studied heavy metals are referred to the elements of biological capture of CАB<1. An effective inactivating effect on heavy metals is provided by pre-sowing treatment of pea and soy seeds with biologically active substances combined with Rhizotorphin+Agrica and Rhizotorphin+Humariz.

An analytical method for the quantitative determination of antioxidant sodium metabisulphite in veterinary drugs has been proposed by spectrophotometric method. Based on the literature data, the optimal conditions of the analytical reaction were selected experimentally. The dependence of the value of the analytical signal on the temperature of the reaction medium, concentration of p-rosaniline and duration of the reaction was investigated to establish the optimal conditions of the analytical reaction and obtain a stable analytical signal. The stability of the colored analytical form in time was also checked and the linear dependence of the value of the analytical signal on the concentration of sodium metabisulphite was investigated. The analytical reaction at room temperature is optimal. The maximum analaytical signal is achieved by carrying out the analytical reaction for 10 minutes and then practically does not change for an hour. To achieve the maximum analytical signal, it is necessary to use a 20-fold excess of dye relative to sodium metabisulphite. The analytical signal remains stable only for the first hour, then gradually begins to decrease. Metrological characteristics of the method of determination of metabisulphite in veterinary drugs are calculated, the limits of spectrophotometric determination are 0.33 – 2.50 μg/ml. The correctness of the developed method was checked on model solutions by the method of "introduced-found" method of comparison in the presence of various biologically active substances that are part of drugs together with sodium metabisulphite. The content of sodium metabisulphite in veterinary drugs of domestic and foreign production at different intervals of their storage time was established. It is shown that the content of sodium metabisulphite in drugs decreases during their storage time, until complete disappearance, which directly affects the content of the active substance, because in the absence of antioxidant oxidative processes with biologically active substances begin to take place.

Background. Taking into consideration the intense rhythm of life, the development of technologies for instant food products of increased nutritional value is urgent. Typically, food concentrates for desserts include fruit or fruit and berry fillings and require cooking to prepare ready-made meals. In this case, heat treatment of the mixture (boiling) negatively affects the thermolabile biologically active compounds. The aim of the work was to develop a recipe for instant food jelly concentrates of increased nutritional value based on encapsulated powdery hibiscus extract. Materials and methods. To encapsulate the aqueous-alcoholic extract of hibiscus and obtain a powdered semi-finished product, swelling potato starch was used. Rheological studies were carried out using a "REOTEST-2" rotational viscometer. Results. In order to enrich food concentrates of instant kissel with biologically active substances, we studied a method for extracting dry hibiscus flowers with aqueous-alcoholic solutions of various concentrations. It was found that the extractivity and the transfer of polyphenolic compounds, including anthocyanins, to the extract are improved when a water-alcohol mixture with an ethyl alcohol concentration of 30 % is used as an extractant. For the preparation of a powdery hibiscus extract, modified swelling starch was used, which has the property of swelling in cold water, which makes it possible not to subject the mixture to prolonged heat treatment for preparing a ready-made dish and to preserve the biologically active substances of the hibiscus extract. In addition, this starch is an effective solid carrier that plays a protective role for thermolabile vitamins and bioflavonoids. On the basis of experimental studies, formulations of instant jelly have been developed, which include fructose, powdered hibiscus extract, apple pectin and ascorbic acid. The study of the rheological properties of semi-finished products based on hibiscus extract, as well as ready-made jelly, testifies to the receipt of a finished dessert with a delicate creamy consistency. Conclusion. A method for obtaining a powdery encapsulated hibiscus extract based on swelling potato starch and a composition of a food jelly concentrate using this semi-finished product have been developed. It was found that for the extraction of raw materials it is better to use a water-alcohol mixture with an ethanol content of 30 %, since most of the anthocyanins are converted into the extract under these conditions. The developed semi-finished product of dry hibiscus extract can be used as a thickener, acidifier and colorant in recipes for food concentrates for instant dessert dishes. Due to the use of swelling starch, food concentrates of jelly do not need to be boiled, and the presence of vitamins, organic acids, flavonoids and especially anthocyanins in the hibiscus extract increases the nutritional value of the finished product.
