Abstract
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.
