NEW PROCESSES FOR OBTAINING MANNOPROTEINS FROM BEER YEAST SEDIMENTS AND THEIR BIOCHEMICAL PROPERTIES

Abstract

The paper provides information on a new process of extracting mannoproteins from yeast sediments from waste from the beer industry. The process is characterized by the use of wastes that pollutes the environment, the reduction of the time, the autolysis temperature and the amount of ethyl alcohol used. The content of mannoproteins is 41.34 - 44.8 % dry biomass, being 7 - 16 % higher compared to the control variant. The mannoproteins obtained according to the process have a varied biochemical composition and high catalase and superoxide dismutase activities. The obtained results present an opportunity for application in zootechnics, food, pharmaceuticals, medicine and agriculture.
