Effect of Ultrasonic Wave on Lentinan Extraction


Article Preview

The research in this paper optimized the extraction technique of lentinan with ultrasonic assistant method on the basis of hot water extraction technique, and investigated the promoting function of ultrasound to polysaccharides extraction. Extraction condition was selected by means of orthogonal experimental design, four factors and three levels L9(34), after key elements were respectively chosen through single factor experiments. Comparison between optimal extraction parameters of two method, hot water extraction technique and ultrasonic assistant extraction technique, showed decreased extraction temperature and significantly shortened extraction time, which existed in the second means, improved the extraction efficiency. Lentinus edodes polysaccharide extracted with ultrasonic assistant technique, the extraction rate and polysaccharide content percentage increased 6.22% and 8.66% respectively, comparative to which extracted with hot water extraction technique.
