The brewing industry is a large producer of waste, which includes brewer's spent grain, brewer's spent yeast, and various auxiliary and packaging materials. Brewer's spent grain and brewer's spent yeast as organic industrial waste, represent materials rich in complex carbohydrates. In this paper, the potential of brewer's spent yeast and brewer's spent grain for the isolation of mannan-type polysaccharides and their hydrolysis to D-mannose, which finds application in the pharmaceutical industry, as well as the possibility of using these by-products in the food industry, was examined. Analysis of samples of brewer's spent grain and brewer's spent yeast determined their chemical composition. After that, the yeast cell wall was isolated from a sample of brewer's spent yeast from which mannans were extracted. After mannan extraction, proteins were removed and acid hydrolysis was performed. The resulting purified precipitate was analyzed by thin-layer chromatography (TLC).
