白酒丢糟糖化降解液的制备条件探讨

Investigation on the Saccharification and Degradation of Distiller's Grains

以降解白酒丢糟中的可降解多糖为目的,通过研究酶法和化学法对丢糟中的粗纤维及粗淀粉的降解发现,2%的HCl与丢糟粉按401∶混合后在120℃高温下处理混合物45 min,对丢糟粉的降解有较好的效果,丢糟粉的降解率可达到36.76%。降解后的糖酸混合液通过阴离子交换法可实现糖酸的分离。将酸降解与酶法相结合也对提高丢糟粉的降解率有一定的效果。

In order to degrade the degradable polysaccharide in spent grains,it was found throught the study of the degradation of crude fiber and crude starch in spent grains by enzyme method and by chemical method that the mixture of 2 % HCl and spent grains powder(ratio as 40∶1) could achieve satisfactory degradation effects(degradation rate as 38.76 %) under the conditions of 45 min treatment at 120 ℃.After the degradation,sugar and acid could be separated successfully by anion exchange.And the combination of acid...
