Состояние пищевой системы утфеля i кристаллизации при совокупном действии пав, деколоранта сахара, антинакипина

At the present stage for the sugar beet factories of the CIS countries in connection with the entry into the world market, a trend for high quality white sugar production appeared. It is shown that the white sugar quality is largely determined by the state of the food system of the I crystallization massecuite, in the formation of which technological aids for the functional groups of surfactants, sugar decolorants, and descaling agents (descalers) are used. It is noted that between the means applied, joint interactions are possible in the form of antagonism-synergism, which ultimately affect the white sugar quality. In this regard, it is advisable to study the cumulative effect of the means of these functional groups on the change in the state of the nutritional system of the massecuite I. This task was solved using the previously developed methodological approach based on determining of representative indicators of the solid and liquid phases of the massecuite food system — crystal content, heterogeneity coefficient, average crystals size, viscosity, chromaticity, calcium salts content, the optimal values of which indicate the food system steady state, deviations from them - unstable. The experiments scheme included 5 combinations with local and joint ontroduction of Defospum surfactant, E 221 sugar decolorant, Kebo DS descaler. It was revealed that with the combined application of surfactants and sugar decolorant, the food system of the massecuite was characterized by a steady state at the best values of indicators: the color of the liquid phase was 5.8% lower compared to the autonomous use of decolorant, viscosity - 1.6% lower than the autonomous use of surfactants. It was suggested that this is due to the synergistic effect, in the first case - surfactant on the functional effect of the sugar decolorant, in the second - on the contrary, the decolorant on the functional effect of the surfactant. It was shown that the sugar obtained from such a food system corresponded to the white sugar of the TC1 category. Descaler residual quantities migrating into the food system of the massecuite antagonist to the decolorant of sugar and surfactant, makes it unstable
