摘要
Abstract
Polysaccharide was extracted from defatted wheat germ with water as extracting agent by ultrasonic-assisted method. The effects of solid-liquid ratio, ultrasonic extracting temperature and time, ultrasonic power on the polysaccharide extraction rate were studied, and the optimum extraction parameters were confirmed through the single factor and orthogonal experiments. The results showed that the optimum solid-liquid ratio was 1∶13 (m/V), extraction temperature was 65℃,extraction time was 40 min,and ultrasonic power was 300 W. Under this optimum condition, the extraction rate of polysaccharide was 92. 33%, significantly higher than that without ultrasonic (38.70%).关键词
