金针菇加工副产物酶解及脱色工艺研究

Study on the Enzymatic Hydrolysis and Decoloration Process of the Processing by-products of Flammulina velutipes

金针菇在加工过程中会产生菌柄、菌盖、畸形菇等下脚料,多数未经处理而直接丢弃,既污染环境又造成极大的资源浪费。以金针菇下脚料为原料,采用复合酶法进行了金针菇酶解工艺研究,然后利用活性炭对酶解液进行脱色处理。结果表明,在最佳工艺条件下,金针菇加工副产物酶解液氨基酸含量达到30.08 mg100mL,酶解液脱色率为26.34%。

There were waste, such as stipe, cap and deformed mushrooms in the processing of Flammulina velutipes. Most were directly discarded without any treatment, which both polluted the environment and caused great waste of resources. In this study, the enzymatic hydrolysis and decoloration process of the processing by-products of Flammulina velutipes were studied. It was showed that under the optimal condition the amino acid content of Flammulina velutipes hydrolyzate reached 30. 08 mg/100mL, and the decolorization rate of hydrolyzate was 26. 34%.
