摘要:

以啤酒糟为原料,采用超微粉碎和超声波辅助法提取水溶性多糖。通过清除羟自由基(·OH)、超氧阴离子自由基(O2 - ·)和1,1- 二苯基-2- 三硝基苯肼(DPPH)自由基能力的检测,证明啤酒糟水溶性多糖具有一定的抗氧化活性。研究水溶性多糖复合果汁饮料的加工工艺,通过感官风味评价制备出一种新型的水溶性多糖复合果汁饮料。该水溶性多糖复合果汁饮料中水溶性多糖含量2g/100mL、总酸0.5430g/100mL、总糖12.15g/100mL、VC18.97mg/100mL、蛋白质0.2029g/100mL,是补充VC 和水溶性多糖的优质饮料。

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.
