Currently, special attention is paid to the use of industrial by-products, in particular those obtained in huge quantities in the brewing and wine making process, as a source for the production of natural preparations with high biological value. In this study are presented results related to the recovery of beer yeast biomass from the sediments of the beer industry, by obtaining lipid extracts with valuable biochemical composition. Thus, applying the optimized autolysis method, with the use of sodium phosphate buffer at 45°C for the destruction of the cell wall and fractional extraction with hydric, alkaline and acidic solutions, various liquid and solid fractions were obtained from the biomass of brewer’s yeast with varied lipid content. So, in order to optimize the waste processing process of the beer industry and the complex recovery of yeast biomass, it is reasonable to include the lipid fraction extraction stage in the technological flow, after obtaining protein and mannoprotein extracts, which will be useful and as an additional step of purification of the β-glucan fraction. |
