The article describes the physico-chemical and fire-hazardous properties of substances and materials related to the shopping center «Dream» in Semey. It is planned to design an automatic fire extinguishing installation at the facility and the state of the technical means of automatic fire protection in it. Extensive development of fire automation means guarantees the protection of people's lives from fire hazards, increases the reliability of successful fire extinguishing, creates an opportunity not to turn into a large fire, ensures the safety of material values. Large-scale firefighting automation of the facility on a large scale increases the percentage of «unmanned technologies».

The article presents the influence of the extrusion method on the sanitary condition of the finished compound feed, as well as studies of the quantitative and qualitative composition of the microflora of raw materials of plant and animal origin used in the production of compound feeds for valuable fish species (jade perch, pike, walleye). Compound feeds were developed in the conditions of the Golden LLP plant Fish.kz", the study was conducted at the Kazakh Research Institute of Processing and Food Industry in Almaty. Studies have been conducted to identify pathogenic microflora in 4 samples of raw materials (fish meal, meat and bone meal, wheat, rapeseed meal) and in 3 samples of extruded compound feeds (compound feed for jade perch, pike and walleye). The analysis of the listed raw materials objects showed that the detected total microbial number of pathogenic microorganisms and conditionally pathogenic do not exceed acceptable indicators. The analysis of 3 samples of finished compound feed showed that the samples after extrusion are sterile and the results of studies of the sanitary condition of experimental extruded fish feeds indicate that the heat treatment of the raw materials used in the production process ensures appropriate requirements for the quality and safety of compound feeds in relation to the established microbiological standard and the use of these products for fish cultivation.

Beef rumen (up to 20%) and beet (up to 30%) were additionally added instead of minced beef in the recipe of meat cutlets. Studies showed that the water-binding capacity in variants 3 and 4 is significantly higher than that of variants 1 and 2 (P<0.05). Indicators of waterholding (WHC) and fat-holding capacity (FHC) in minced meat cutlets without adding rumen and beets were 61.63% and 62.69%, while with adding 20% of the rumen and 20% of beets (Variant 3) these indicators increased to 69.41% (P<0.05) and 66.82%. The pH analysis is characterized by an increase in values when replacing meat with rumen and beets. A significant decrease in the limiting shear stress was observed in variant 4, when 30% of beet and 20% of rumen were added, with the meaning of 442.84 Pa. The most optimal amount of added ingredients is between 10 and 20% of both the rumen and the beets.

This article discusses the activity of the amylase inhibitor in the sprouts of wheat grains in the resting state and the difference in the quantitative content of the subtilisin inhibitor in different wheat varieties. The research work was developed on the basis of domestic and foreign articles on this topic. Grains of cereals have the ability to synthesize and accumulate various protein inhibitors of proteases and amylases. Inhibitors are an effective mechanism for preventing phytopathogens from harming the plant, as the inhibitor has the ability to inhibit the activity of phytopathogen hydrolases. The pathogen allows you to increase the stability and endurance properties of the plant by inactivating the enzyme of the microorganism. Inhibitors have been found to have a function mainly in the case of plant damage and to be able to resist pathogens and insects. Serine proeteinase inhibitors are currently considered to have been studied in more depth. There is relatively little information about amylase inhibitors. And of great interest to researchers, it is he who is a bifunctional inhibitor. That is, it has the property of inhibiting α-amylase and serine protease subtilisin in unrelated sprouts. The main problem of the study of inhibitors is their use in the fight against pathogens and pest insects and obtaining transgenic plants with increased resistance to pathogens.  

As an alternative source of vegetable protein, waste from the processing of oilseeds of the Brassicaceae family is of particular interest. The article presents the results of a study of the functional and technological properties of a protein isolate from rapeseed cake of the Siberian variety. The following were determined: water-binding and water-retaining abilities, fat-retaining ability, emulsifying ability and stability of the emulsion. The influence of the pH of the medium on the foaming and stability of the foam of the protein isolate of rapeseed was also investigated. As a result of the study, it was found that with a hydromodule of 1:3, rapeseed isolate has the maximum indicators of water-binding and water-retaining abilities. When adding 1 cm3 of oil per 1 g of rapeseed isolate, its fat-holding capacity was 100%, further decreasing as the amount of oil added increases. During the experiment, it was revealed that rapeseed isolate has a high emulsifying ability and emulsion stability. As a result of the study, it was found that a decrease in pH to 2 leads to an increase in foam capacity (by 30%) and foam stability (by 50%) compared to pH 10. It follows from the results obtained that rapeseed isolate is able to increase the water-binding, moistureretaining, fat-retaining, emulsifying abilities of meat systems. Thus, it has been established that protein isolate from rapeseed cake of the Siberian variety may be of interest as an alternative to soy protein, and is a promising technological additive for use in meat products.

Cryogel is a kind of cryogenic polymer material that consists of three-dimensional flexible polymer structures obtained by freezing-thawing. In this work, cryogels based on the natural polymer gellan were obtained by ionotropic gelation in the presence of NaCl and CaCl2. The properties of the obtained cryogels – morphological characteristics, swelling kinetics, mechanical properties and structure of the gels – are investigated. The indicators of scanning electron microscopy demonstrate a porous matrix with a system of communicating pores. There is an increase in the number of pores with an increase in the concentration of gellan. The average pore diameters of cryogels have been determined. The degree of swelling of cryogels samples is calculated. Higher values of the swelling degree of 18.2 and 19.4 g /g are observed in cryogels obtained at a higher concentration of gellan – 2%. The results of the study of the mechanical strength of cryogels show an increase in the Young's Modulus with an increase in the concentration of gellan, as well as the absence of destruction even when 99% of the compression ratio of the samples is reached. The mechanical properties of cryogels are one of the advantages of this type of materials, since they have the property of repeatedly and reversibly experiencing external mechanical effects. The chemical structure of the synthesized cryogels based on gellan is proved by the method of FTIR spectroscopy. In the IR spectra of cryogel samples, characteristic peaks of deformation and valence vibrations of functional groups that are part of the gellan were detected.
