As know, all wood material is recycled only half, and the rest of it remains unused. In practice, wood waste is most often plowed or burned, at a time when such wood is a valuable natural raw material that can compensate for the needs of a number of sectors of the economy. In this regard, the problem of recycling waste from the woodworking industry is very relevant today. Wood waste contains a large amount of substances capable of exhibiting biological activity. In particular, such biologically active substances include betulin, which is found in birch bark, which, due to its many advantages, has found wide application in medical, perfumery, cosmetic, food and other industries. For the rational use of wood and wood materials, it is necessary to develop new technologies and equipment for processing wood into products that are in demand for mankind. The paper provides an overview of the processing of birch bark. The relevance and prospects of birch species as a raw material for the chemical industry have been established. An installation for obtaining biologically active substances from wood waste is presented.

It is well–known that cranberry is an especially rich and heterogenic source of phytochemical substances. Modern technologies allow to produce food products of wild fruits and berries, but they use their diverse and useful chemical composition insufficiently. The aim of the work was in studying features of the chemical composition and content of biologically active substances in cranberries, harvested at the territory of Ukraine, and the influence of processing technologies of cranberry on main indicators of its chemical composition at producing juices. It was established, that the maximal extraction of biologically active substances is possible at juices production using biocatalysis method, because the essential part of functional elements in the raw material is in the bound condition and is a base of cellular walls that is why it is expedient to disturb nativity and integrity of these natural biopolymers. There was experimentally grounded the influence of a processing technology on the quality of cranberry juice. There was studied the phenol composition of cranberry composition and influence of different ways of fermentolysis on PS extraction. It was confirmed by results of the study of the fraction composition of phenol substances, that their maximal extraction is achieved after the enzymatic processing of pulp and momentary heating to inactivate the effect of enzymatic preparations. It was proved, that enzymatic biocatalysis of cranberry pulp also favors the essential increase of the output of organic acids (lemon, apple, amber), sugars (fructose, glucose), sorbite polyalcohol and also phenol substances of cranberries. The mechanism of the enzymatic complex influence on cranberry pulp at fermentolysis was demonstrated. The use of products of cranberries processing at food products manufacturing will allow: to enrich the chemical composition, to compensate deviations of functional–technical properties of the raw material and to introduce resource–saving technologies. Based on the researches there were substantiated perspectives of using juices and marc of cranberry in different branches of the food industry: non–alcoholic, meat processing and at manufacturing products of the restaurant industry.

Abstract At present, the preservation of the consumer properties of berry products is an urgent problem. Use of fresh garden strawberries is limited by a short storage period and seasonality. Under optimal storage conditions in a normal atmosphere, the average shelf life of strawberries is from 2 to 9 days depending on the variety. To meet the needs of the population in garden strawberries and meet the physiological needs in a unique complex of biologically active substances, strawberries are subjected to different processing methods. Drying being a type of fruit and berry products processing has the following advantages: a significant increase in the shelf life of products, a decrease in the mass and storage volumes of dried berries, preservation of minerals, carbohydrates, dietary fiber, antioxidants, bioflavonoids and many biologically active compounds in berries. Modern drying technologies allow preserving the content of essential vitamins to its full extent. Comparison of two technologies for drying garden strawberries has established that vitamins and other biologically active substances are well preserved in berries. Berries dried by convective vacuum-impulse method (CVI) are recommended to be used for food enrichment.

Microalgae are a group of autotrophic microorganisms that live in marine, freshwater and soil ecosystems and produce organic substances in the process of photosynthesis. Due to their high metabolic flexibility, adaptation to various cultivation conditions as well as the possibility of rapid growth, the number of studies on their use as a source of biologically valuable products is growing rapidly. Currently, integrated technologies for the cultivation of microalgae aiming to isolate various biologically active substances from biomass to increase the profitability of algae production are being sought. To implement this kind of development, the high productivity of industrial cultivation systems must be accompanied by the ability to control the biosynthesis of biologically valuable compounds in conditions of intensive culture growth. The review considers the main factors (temperature, pH, component composition, etc.) that affect the biomass growth process and the biologically active substance synthesis in microalgae. The advantages and disadvantages of existing cultivation methods are outlined. An analysis of various methods for the isolation and overproduction of the main biologically active substances of microalgae (proteins, lipids, polysaccharides, pigments and vitamins) is presented and new technologies and approaches aimed at using microalgae as promising ingredients in value-added products are considered.

The article presents the results of author scientific research dealing with the use of saponins, biologically active substances in food and cosmetics technology. The problems of their formation in plants, the chemical nature and the features are considered, biological and physico-chemical properties of saponins are studied. By their nature, saponins are divided into steroid and triterpene, differing by glycoside part of a molecule, thus, with different biological and chemical properties, but they are all capable to develop foam in aqueous solutions, and this feature is the origin of their name. The name originated from the word «Sapo», which means soap. It should be noted that at present saponins are not studied fully as other biologically active substances (BAS), although they are of interest and relevance. In the course of scientific work, about 20 species of saponin-containing plant material, both steroid and triterpene ones, were selected and analyzed for the determination of saponins. The selection of raw materials with the highest content was performed for their further use in cosmetics and as the surfactants in the production of emulsion food products. The following research methods were used in the work: qualitative reactions to the presence of saponins, foaming, saponin extraction, the release from dry aqueous extract of both steroid and triterpin ones. The method and the scheme of their release and precipitation are presented in the article.The work was carried out within the framework of the state assignment of FSBEI HE «Moscow State University of Food Production» No. 14.7404.2017/бч «Scientific and applied bases of application of traditional and nonconventional vegetable raw materials and secondary products of its processing (fruit and berry, grain, bean, oil, essential oil, herbs) in technology of specialized products of the food industry, cosmetology and pharmacy»

Topicality. Incidental products of soy processing (okara, meal, millcake) contain a large amount of protein, and, additionally, other valuable biologically active substances. Among them, isoflavones are of particular researchers’ interest. Subcritical water extraction is a promising method for elicitation biologically active substances from plant raw material. However, such a method of extracting isoflavones, and its rational parameters for soy meal, remain insufficiently investigated. Aim and methods. The aim of this work is to study the influence of parameters (temperature: 120...160°С, duration of extraction: 5...15 min, hydromodule: 1:15...25) of the extracting process of soy meal with subcritical water on the isoflavones content in the dry material of the extract. The empirical research method is applied, using the second-order orthogonal compositional outline for a fractional factor experiment. The samples of soy meal extract are obtained using the experimental setup, based on the high-pressure reactor “RHP-2-500”. The total isoflavones content in the dry extract material is defined in terms of gallic acid with absorption spectrophotometry method. Results. Based on the obtained results, the quadratic interpolation model is constructed. This model links the total isoflavones content in the dry extract material with the extraction parameters. The analysis of the constructed model makes it possible to establish rational measures of extraction parameters. Conclusions and discussion. In this study, the intensive growth of soflavones content in the dry extract with highing the temperature process, and a relatively small influence of the process duration on this indicator, were defined. The influence of the hydromodule is ambiguous. The lowest yield of isoflavones is noted at hydromodule ≈1:21,41. Its increase or decrease lead to the growth of isoflavones content in the extract. In this paper, for the first time, the existence of rational measures of parameters in the process of extracting isoflavones with subcritical water from soy meal is studied and established. The obtained results can be used in the elaboration of the technology for producing isoflavones enriched soy protein concentrate.
