Abstract:

Objective: To optimize the extraction processing of polysaccharide from waste materials Pleurotus eryngii. Method: On the basis of single-factor experiments and the principles of Box-Behnken central composite experimental design, response surface methodology (RSM) with 3 factors and 3 levels was used to explore the effect of each factor on extraction rate of polysaccharide. Results: The optimal extraction processing conditions of polysaccharide were extraction temperature of 88 ℃, extraction time of 8.5 h and water-material ratio of 57:1 (mL/g). Under the optimal extraction conditions, the extraction rate of polysaccharide was up to 6.43%. Conclusion: RSM can improve extraction rate of polysaccharide from P. eryngii.

Key words: Pleurotus eryngii, waste material, polysaccharide, response surface methodology (RSM)
