Abstract

Long-term storage of large volumes of sugar beets, due to an increase in the production capacity of enterprises, leads to a decrease in the technological quality of raw materials. Unstable weather conditions cause freezing and subsequent thawing, which destroys beet tissue, increasing its accessibility to microorganisms. Processing of substandard raw materials is accompanied by the use of a whole range of bactericidal drugs at different stages of production, to which resistance of the accompanying microflora develops over time. To reduce the degree of infection of intermediate products at the production site, it is proposed to use a bactericidal preparation based on the sodium salt of dichloroisocyanuric acid (DCCN), which can be introduced into the extractant before feeding it into the diffusion apparatus. The influence of the quantity, concentration of the DCCN solution and the temperature of the extractant on the qualitative characteristics of diffusion and purified juices was experimentally established. A positive effect of DCN was revealed during the processing of beets contaminated with Leuconostoc mesenteroides. Using mathematical modeling methods, regression dependencies were obtained that reflect the relationship between process parameters and quality characteristics of juices. The optimal parameters for the use of DCCN in preparing the extractant for the diffusion process have been established: temperature 65 °C, concentration of the DCCN solution 0.05 %, its amount 15 %. This drug can also be used at the stages of storing sugar beets, processing beet chips before extraction, and disinfecting equipment.
