Study on Extraction Technology of Polysaccharides from Auricularia auricula

On the basis of single factor test of water to material ratio,extraction temperature,extraction time and microwave time,four factors and three levels of the orthogonal experiment was designed to optimize the extraction technology of polysaccharides from Auricularia auricula in Hezhou of Guangxi using microwave assisted water extraction method.The results showed that the optimum extraction conditions were as follows:water to material ratio 30 mL/g,extraction temperature 80℃,extraction time 2.0 h,microwave time 3 min.Under these conditions,the yield of Auricularia auricular polysaccharide was 3.972%,was much lower than other polysaccharide that has been reported,needs to be further research.
