Abstract

Compared the High-speed Shear Dispersing Emulsifier (HSDE) and the Enzymic Method to extract polysaccharides from Auricularia auricular by treating the Auricularia auricular polysaccharides yield as the indicator. The results showed that the optimum conditions for HSDE were: shearing speed 21 000 r/min, solid-liquid ratio 1︰110 (m/V), shearing time 6 minutes and temperature 80 ℃; the optimum conditions for enzymic method were :concentration of enzyme 1.2%, enzymatic hydrolysis time 60 min, pH 5.5 and temperature 55 ℃. The extraction yields were 24.43% for HSDE and 9.29% for the enzymic method. Compare to the enzymic method, HSDE is more effective, time-saving and easy-to-use, which is the more appropriate method for polysaccharides extraction from Auricularia auricular.
