The article analyzes the ways of ensuring a stable quality and use of biopreparations patented in Russia and abroad. The most famous biopreparations developed by Russian scientists. The analysis of literature sources and patent information has show that the development of methods for storing plant raw materials with using biological protection means is actual. Research in the field of the use of biopreparations for the processing of agricultural products is of high practical importance, since they allow a significant reduction in losses during storage. The application of biological protection treatment technologies is the most effective, environmentally safe and economical way of preparing for storage of plant raw materials

The article presents the comparative characteristics of the current (diffusion) and developed (diffusion-press) sucrose extraction technology from sugar beet cossettes. We have presented the graphs of the influence of raw juice pumping value on its cleanliness and residual content of sucrose in partially desugared beet cossetes, the influence of partially desugared beet cossetes pressing power on residual content of sucrose in the pressed pulp and losses of sucrose with pressed pulp and also the technological scheme and regimes of diffusion-press extraction of sucrose from sugar beet cossettes. The criteria for determining the boundary parameters of diffusion and press sucrose extraction stages are identified. The comparative assessment of technological and economic indicators of the existing and the developed technologies of sucrose extraction from the beet cossettes is shown. The developed technology allows reducing raw juice pumping value simultaneously increasing its purity, thereby providing reduction of auxiliary materials and energy resources consumption, as well as increasing sugar yield. The technology of diffusion-press extraction of sucrose is implemented on 2 sugar beet factories of the Russian Federation. The economic effect from its implementation is more than 45 mln. rubles

The article presents the results of studying the influence of some types of packaging materials used in conjunction with Inter Fresh’s ethylene absorber (sachets) on commercial quality and losses of Alexandria zucchini, Lyubov sweet pepper and tomatoes cv. Inkas during storage. The study was carried out using StePac Xtend bags, creating a modified atmosphere. The objects of research were stored for 14 days at a temperature of 8 – 10 °С and air relative humidity of 90±3 %. One sachet for ethylene absorption was placed in Xtend bags. It was found that when stored under these conditions, the total weight loss is: for tomatoes – 0.3% when using Xtend bags and Inter Fresh ethylene absorbers, 1.8% when using traditional packaging materials; for zucchini – 0.4% when using Xtend bags and Inter Fresh ethylene absorbers, 1.6% when using traditional packaging materials. Losses associated with microbiological damage during storage of zucchini and tomatoes were not observed. During storage of sweet pepper microbiological spoilage took place, which, apparently, was the result of increased contamination with pathogenic microorganisms
