“…Besides, a large (in comparison with other types) mass of native protein decreases the tolerance level and slows down significantly the absorption speed Formulae with free amino acids can be more preferable due to main component low molecular mass which obviously indicates a high speed of absorption. But even under ordinary conditions two thirds of nitrogen are absorbed in the form of peptides in intestine (peptides have independent mechanisms of passive transport, but free amino acids are transported by specifically active transport systems), but under the conditions of stress and progressive starvation this indicator is even higher for absorbable peptides and this reduces sharply the effectiveness of the nutritional formula based on free amino acids [25]. There is evidence that formulae based on amino acids, as well as parenteral nutrition and starvation, result in intestine mucosa atrophy [9].…”

The main component of human health is nutrition which becomes even more important if a person is sick. In the body of cancer patients metabolic processes change, so he/she requires a special diet. Probiotics and short peptides are the integral part of the diet of cancer patients. One of the goals of nutritional support for cancer patients is the visceral protein pool maintenance. In modern formulae for enteral support for cancer patients the protein component can be represented in one of three types: native protein; cow’s milk whey/whole protein peptides; free amino acids. The present article deals with study on biotechnological treatment influence on milk protein controlled hydrolysis process with the aim of deriving biologically active peptides, as well as of studying several qualities: immunomodulatory, cytotoxic, antioxidant and prebiotic. Conditions for enzymic hydrolysis of milk proteins are optimised, which provide deriving biologically active directional peptides. The optimal parameters of hydrolysis conduction are chosen, which provide the polypeptide chain division into peptides and free amino acids, as well as enzymic system was chosen, consisting of chymotrypsin or thermolysin at a temperature of 37±2°C, in the enzyme-substrate ratio of 1 to 50 and process time of 12.00±0.05 h. The qualities of biologically active peptides (immunomodulatory, cytotoxic, antioxidant and prebiotic), derived from milk proteins, are studied. The studies demonstrated that all peptides under study have anti-tumour qualities, at the same time increase in biopeptide concentration causes decrease in the capacity for survival of different line cancer cells

It has been proved in the work that non-traditional, annually renewable wastes of plant raw materials − cuttings of fruit trees, hop stems and castor bean stems − are rational to be used for further biotechnological processing in order to obtain a valuable protein feed supplement. The negative impact of burning these plant wastes on soil microbiota has been confirmed. Technological properties, chemical and biopolymer composition of the plant waste have been studied. It has been found out that the optimum particle sizes for all three types of the studied waste are 20–35 mm in fibre length. Such grinding degree provides the best diffusion of the hydrolyzing agent into the particles of the raw material and the extraction of monosaccharides into the solution. All types of the analysed plant waste have a high content of polysaccharides, extractive substances, which will allow to use them as potential raw materials for the development of nutrient media to cultivate microorganisms in biotechnological industries. Acid degradation of biopolymers of the analysed raw materials has been carried out in laboratory conditions. Hydrolysate-based nutrient media have been obtained in laboratory conditions and their biological quality has been studied. Yeast culture strains, which are able to grow actively on the hydrolysates of fruit tree cuttings, hop and castor bean stems, have been selected, and Candida tropicalis culture has been cultivated during the process of periodic cultivation. The negative impact of burning plant residues on the soil microbiological status has been investigated. Samples of the soil were taken from the experimental plot before and after burning of the plant waste, microbiological studies of the total number of mesophilic aerobic and facultative anaerobic microorganisms, and nitrogen-fixing ones were conducted, since they are the only living organisms capable of absorbing molecular nitrogen from the air and incorporating it into the cycle of nitrogenous substances. The total number of microbes is reduced by 45%, and the number of nitrogen-fixing bacteria is halved. The process of their regeneration is rather slow, which will significantly affect soil fertility, and soil ashing can lead to changes in crops capable of producing high yields on this soil, and will require scientifically based crop rotations.

Introduction. The present research featured some aspects of developing advanced technologies for the future agro-industrial sector of Russia. The paper focuses on a synergistic approach to new complex self-organizing technological systems in food industry. The research objective was to set up scientific foundations for the agro-industrial complex, industrial production of agricultural raw materials of plant and animal origin, and their industrial processing into food. Results and its discussion. The research touched upon the following issues: the conditions for an innovative technological breakthrough into the future of the agro-industrial complex; a dialectic model of technological development; a new industrialization of the agro-industrial complex; the possible economic effect of end-to-end agrifood technologies; the shift from the 4th to the 5th, and eventually to the 6th, techno-economic paradigm in the Russian agro-industrial complex. The article gives a detailed description of the dialectical method, which complicates each technology while simplifying the functioning processes as a whole. Conclusion. Hi-tech development in all branches of Russian agro-industrial complex will make it possible to enter the 6th technoeconomic paradigm and secure domestic food industry in terms of quantity and quality. The article describes prospects of the advanced development of agro-industrial technologies. In addition, it introduces a roadmap for agroscience development: new research should be based on scientific forecasts for the latter half of the XXI century.
