ESTIMATION OF CONSUMER PROPERTIES OF TOPINAMBURS POWDER
In recent years, food products with a functional orientation have been widely used due to the introduction into the formulation of components of plant origin containing physiologically functional ingredients. They are increasingly using local types of plant raw materials and products of their processing. Jerusalem artichoke is a promising vegetable raw material. Jerusalem artichoke tubers are distinguished by a high content of biologically active substances, such as: proteins, inulin, pectin, dietary fiber, macro- and microelements, vitamins. Jerusalem artichoke tubers have poor keeping quality, since during storage they intensively lose moisture. In this regard, one of the most rational ways of their processing and storage is drying and obtaining a powdery semifinished product. Powders contain in their composition a significant amount of biologically active substances, they differ from other products in lower humidity, microbiological stability and the smallest volume during transportation and storage. The article presents the results of studies of Jerusalem artichoke tubers powder by organoleptic, physicochemical and microbiological quality indicators. It was found that the powder from Jerusalem artichoke tubers has high consumer properties and is a safe raw material for further use.
