Background. Sugar refineries cannot modernize the current processing technology and increase their capacity in proportion to the increasing harvest of raw beets. This entails an increase in the processing time. Sugar beets are not subject to long-term storage, and when they are stored in inappropriate conditions, root crops rot, resulting in sugar loss. The aim of this study is to increase the safety of beets during long-term storage before processing and to develop a device for its implementation which will lead to an improvement in the biological value of sugar beet root crops and an increase in the efficiency of technological processes. Materials and methods. The experiment used sugar beets from the Koksu sugar plant and was carried out by treating sugar beets with an ion-ozone mixture to increase their shelf life. The treatment was carried out in an ion-ozone installation. Physicochemical and microbiological analyses were carried out using several methods: chemical extraction, potentiometry and photocolorimetry. Results. The results of the study showed that when sugar beets were treated with ozone at a concentration of 0.5 g/m 3 and 2 g/m 3 , the acidity decreased to 0.6 degrees, and the sugar content increased by 2.3% and 3.3%, respectively. When sugar beets were processed with an ozone concentration of 2 g/m 3 and a molecular ion concentration of 1,000,000 units/cm 3 , a decrease in moisture was observed to 69%, the acidity decreased 2 times and the sugar content increased by 3%. When the beets were processed with an ozone concentration of 2 g/m 3 and a molecular ion concentration of 1,000,000 units/cm 3 , a decrease in acidity was observed to 0.65-0.67 degrees, and the sugar content increased by 2-2.5%. Also, in all the above optimal processing conditions, a decrease in yeast growth was observed. Conclusions. As a result of the study, the following three optimal conditions were established for the processing of sugar beet root crops before storage: an ozone concentration of 0.5 g/m 3 and 2 g/m 3 ; an ozone concentration of 5 mg/m 3 and molecular ions of 500,000 units/cm 3 ; an ozone concentration of 2 g/m 3 and molecular ions of 1,000,000 units/cm 3 .

Proper organization of storage of raw sugar products allows for a long time to maintain product quality and minimize loss of its mass. Difficulties are associated with the high content of free water in them. We have studied the effect of ozone treatment on long-term storage of raw sugar products, including sugar beets. Sugar beet samples were taken from the Koksu sugar factory in the village of Balpyk bi, Almaty region of the Republic of Kazakhstan. The plans for full-factor experiments of the type — 23 out of eight prototypes — were drawn up and each of them was processed with different combinations (max and min) of the following factors: x1 - ozone concentration (g/m3), x2 - processing time (min), x3 - overpressure (ati) (the pressure value can be counted from 0 (absolute pressure) or from atmospheric (overpressure). If the pressure is measured in technical atmospheres, then absolute pressure is denoted as ata, and excess pressure is denoted as ati). Physicobiochemical, microbiological properties, and safety indicators were determined for each sample of sugar beet: mass fraction of moisture, dry matter, acidity, pectin, fiber, sucrose, nitrite, heavy metals, pesticides, mycotoxins, the presence of mold and yeast. As a result of the study, it was found that ozone treatment significantly reduces the growth of mold and yeast, contributes to an increase in the content of pectin, fiber and sucrose, and a safety risk assessment of raw sugar products was scientifically provided.

The bakery market is one of the most capacious in Kazakhstan. Manufacturers of bread products are in dire need of the introduction of intensive technologies for improving product quality and safety. This article presents the results of research to develop technology for accelerated production of bread with ion-ozone cavitation treatment. The influence of various modes of exposure to ion-ozone cavitation has been investigated. After baking, bread samples were examined for organoleptic, physicochemical, rheological and microbiological indicators. The optimal method is treatment with ion-ozone at a concentration of 0.0025 units/mg, at a pressure of 1.0 atm for 1 min. As a result, it was proved that this mode accelerates the process of obtaining dough and shortens the fermentation time, and baking bread increases the qualitative and quantitative indicators according to the control method. The results showed that the ion-ozone technology reduces the length of the process of making dough and bread by three times compared to traditional technologies. The developed products with existing analogues in the Kazakhstan market will differ due to their high taste and consumer properties, product safety, long shelf life and low cost.

The article presents the results of an experimental study of Baisheshek barley grain treated with an ion ozone mixture. This study aims to develop an innovative technology for processing barley with an ion-ozone mixture in order to increase their technological parameters, yield, quality, and grain safety. Kazakhstan has sharply increased the export of barley, and all agronomists, producers, and breeders are actively moving to the cultivation of this crop, while increasing production, productivity, improving product quality, reducing their losses and ensuring storage safety are an urgent task. Microorganisms play an important role during storage, they fall into crop production in a variety of ways, and if they fall into unfavorable storage conditions after harvesting, crop production quickly deteriorates, harmful substances such as toxins, mold, and others accumulate in it, which reduces the commodity value. To solve these problems, experimental studies were conducted on barley of the Baisheshek cultivar treated with an ion-ozone mixture with and without using excess pressure (cavitation). The calculated full-factorial design of experiments of the 23 (8 experiments) and 24 (16 experiments) degrees made it possible to obtain regression equations describing the change in the seed, physico-biochemical, and physiological properties of barley of the Baisheshek variety. The solution of a comprehensive model for optimizing programming for different barley indices made it possible to establish optimal technological processing modes and achievable levels of technological qualities of grain. The effect of the proposed technology for ion-ozone and ion-ozone cavitation treatment is the ion-ozone mixture, which produces deodorization, disinfection of grain, following chemical-physical processes, increases biological value, accelerates the processes of grain metabolism. Studies conducted to improve germination, viability, and growth strength show a reasonably clear picture in terms of their ultimate value. Phenological observations showed that the effects of ion-ozone and ion-ozone cavitation treatment is triggered after 25-30 days. It was found that the greatest tendency for superiority is observed with ion-ozone cavitation treatment, followed by ion-ozone, and the control sample is significantly behind.

This study was conducted to determine the impact of the HACCP management system on the safety of final products in baked goods production. The object of the study is two critical control points of the production of bakery products, which in turn affect the indicator of microbiological quality and safety of finished products. Using a mathematical model, the critical limits of critical control points (CCP) were determined – in the baking and cooling processes of baked goods. For the two CCPs, measures for continuous monitoring have been defined and critical limits have been developed. For CCT 1, a theoretical calculation using a mathematical model is given: the critical limit of the baking process (95.2–99.1 °C in the center of the crumb), by controlling this process, the company controls the biohazard factor, for CCP 2 the critical limit of cooling the finished product to a temperature of 22.84 °C in the center of the crumb for safe packing. The presentation of the results of the development of critical control limits and critical points of the production of bakery products using the construction of mathematical modeling is the theoretical beginning of further research. When compiling the model, the physical parameters of a specific dough with a certain geometric shape were used, from which the bakery product is baked. The use of a mathematical model allows predetermining the baking parameters for the dough of any initial concentration. The results can be used in the production of baked goods to better ensure the quality and safety of the final product
