用废啤酒酵母自溶残渣制碱不溶性葡聚糖的研究

研究了用啤酒厂排弃的废酵母经自溶性葡聚糖的工艺，采用了碱制备法及酶－碱制备法，对ＮａＯＨ及蛋白酶用量，ＮａＯＨ作用时间，浓度等进行了较系统的探讨，对多糖产品进行了定性定量分析，得到的产品主要为β（１－３）－Ｄ葡聚糖。

The Preperation of Alkali-insoluble Glucan by the Residue of Autolysed-Yeast

This paper was on the preparation of alkali -insoluble glucan by the discarded brewer's yeast autolysed beforehand. The alkali extraction method and the enzyme-alkali extraction method were carried out. The effects of the amount of NaOH and protease added, the extraction time, the concentration of NaOH on extracting glucan were studied in detail. Quantitative and qualitative analyses were carried out on the final preducts, and the results shew that 9(1 - 3) -D-glucan was the major component of the preducts.
