香菇中多酚类物质提取工艺的优化研究
, PP. 125-128
Keywords: 香菇,多酚,响应面分析法,优化
Abstract:
以香菇子实体为原料，采用Plackett-Burman设计对影响香菇多酚提取效率的8个因素进行筛选，并通过Box-Behnken设计及响应面分析法确定了影响多酚类提取因素的最佳条件。结果表明影响香菇多酚提取的3个主要因素为乙醇浓度、液料比和提取温度；最佳提取条件为香菇过160目筛，以81%的乙醇作溶剂，液料比为34∶1mL/g，先超声处理15min，在85℃的水浴中提取45min，提取3次。根据最优试验条件对模型进行验证，得到香菇子实体的多酚提取量为186.50mg/100gFW，实际值与预测值的误差为3.24%。
