Ultrasonic Extraction of Polysaccharide from Hericium Erinaceus

Single factor experiments and orthogonal test packet method combined with the actual situation were performed to determine the best conditions for the ultrasonic method and the traditional hot water extraction of polysaccharide of Hericium.The experimental results showed that the impact of various factors on Hericium mycelium polysaccharide extraction rate was in the order of liquid ratio ultrasonic treatment time ultrasonic treatment temperature.The optimum conditions were as follows: ultrasonic processing time of 20 min,extraction temperature of 50 °C,liquid ratio of 1∶15,extracting 2 times.Compared with the traditional hot water extraction method,the ultrasonic extraction time was shortened four-fifths,and the polysaccharide extraction rate was 40% more.
