Abstract

Abstract:

Soluble polysaccharides were extracted from brewer s spent grains by ultra-fine grinding and ultrasound-assisted extraction method. Result showed that soluble polysaccharides had strong antioxidant activity. These soluble polysaccharides were used as the supplementary materials to develop a novel polysaccharide beverage. The optimal formula of this beverage (100mL) was composed of 2 g of soluble polysaccharides, 0.5430 g of total acid, 12.15 g of total sugar, 18.97 mg of vitamin C and 0.2029 g of protein. Therefore, this beverage is a high quality drink containing vitamin C and polysaccharides.

Key words: brewer s spent grains, polysaccharide, beverage
