摘要
为促进银耳多糖资源的进一步开发利用以及多糖化合物的产业化,本研究以古田银耳粗多糖提取率为指标,采用单因素试验以及响应面法优化微波辅助提取工艺.结果表明,古田银耳粗多糖的最佳工艺条件为液料比54∶1(mL/g)、微波时间32 min、微波功率420 W,在此条件下多糖提取率为31.27％,与理论预测值(32.025％)偏差较小,表明响应面优化的模型结果稳定、预测性良好.优化后的银耳多糖提取工艺可大大缩短提取时间,节约成本,为银耳多糖深加工提供参考.
Abstract
In order to provide a theoretical basis for the further development and utilization of Tremella fuciformis polysaccharide resources and the industrialization of polysaccharide compounds,the microwave-assisted extraction process conditions were optimized by single factor test and response surface method,taking the extraction rate of crude polysaccharide from Gutian T.fuciformisas the index.The results showed that the optimum conditions for microwave-assisted extraction of crude polysaccharides from T.fuciformis were as follows:liquid-solid ratio 54∶1(mL/g),microwave time 32 min,microwave power 420 W.Under this condition,the polysaccharide extraction rate was 31.27%,and the deviation from the theoretical prediction value(32.025%)was small,indicating that the model parameters optimized by the response surface were stable and predictable.The optimized T.fuciformis polysaccharide extraction process could greatly shorten the extraction time,save costs,and provide a reference for the deep processing of tremella polysaccharide.
