Confectionery products stored in permafrost conditions

Abstract

Industrial development of the Arctic territories is a crucial direction in the development of our country. Expanding the market for confectionery products requires increasing their safety in various climatic conditions, which is only possible by ensuring quality indicators that guarantee their specified shelf life. Studies of confectionery products stored in conditions of unregulated negative temperatures of permafrost, according to organoleptic, physico-chemical and microbiological quality indicators, have been conducted. “Iris Kiss-Kiss” candies, “Strawberry” cookies, homemade crackers, biscuits, and chocolate were stored at unregulated low temperatures. In cookies, crackers, and biscuits, a foreign odor and rancid taste caused by oxidation products of the fat fraction were detected. As for chocolate after storage, heavy bloom and significant changes in structure and consistency were revealed. The moisture content of the chocolate increased. Storage conditions at low temperatures and high humidity increase the risk of microorganism development and microbiological spoilage. The results obtained allow concluding that long-term storage of confectionery products is possible under unregulated low temperatures.
