正交试验法优化灵芝超微粉水提液的工艺研究

Study on optimal water extraction process of Ganoderma super powder by orthogonal test

目的:优化灵芝超微粉水提液的最佳提取工艺。方法:采用L9(34)正交设计,以灵芝干浸膏得率和多糖含量为指标,优选灵芝超微粉水提液的提取方法。结果:最佳提取条件为提取温度为100℃,提取时间为2h,提取次数为4次,加水量为10倍。结论:确定的最佳工艺所得的灵芝多糖和灵芝干浸膏都较高,可为实际生产提供依据。

Objective： To study the optimal water extraction process of Ganoderma super powder. Methods： The orthogonal design L9（3^4） was carried out for the optimal water extraction condition of Ganoderma super powder, the content of polysaecharide and dry extract yield were the referent indexes. Results： The best extraction process was： extractiontemperature100℃ 10 times solve and extracting 2h for four times. Conclusion： The optimal extraction technology is feusible with high content of polysaccharide and dry extract, and provides the basis for the actual production.
