Quality assessment of extracts from unconventional plant raw materials

Abstract

The results of the quality assessment of hydro-alcoholic extracts from black currant and mountain ash sprigs, which are unconventional raw materials for the food industry are given. According to the research, organoleptic, physicochemical and safety indicators of the extracts obtained comply with the requirements of current regulatory documents. This allows their use in technologies of soft and alcoholic beverages, wines, confectionery and canned food as cheap natural flavoring ingredients. The content of phenolic and aromatic substances in the aqueous-alcoholic extracts of sprigs was investigated. The high content of phenolic compounds allows to use extracts in technologies of wellness foods, improve their storage stability. Extracts from sprigs of black currant and mountain ash are the source of valuable aromatic substances with fruit and almond flavor, so can be used for processing into natural flavors. During the research, data about extracting up to 70...90% of toxic elements, contained in raw materials from sprigs were obtained. Therefore, normalization of their concentration in the extracts depends on their content in raw materials, as well as the input control.
