Research the process of autolysis-alkaline process extracting beer yeast β-(1,3)-D dextran;
自溶-碱法提取啤酒酵母β-(1,3)-D葡聚糖工艺研究
The article mainly studied and analyzed the chemical structure and conponents of yeast,pointed out that the way that yeast autolysis combined together with both breaking-wall in temperature difference and high-pressure homogenization can be used to promot the inside things from waste yeast cell and enhance the extract rate,thus searched for the technology in higher extraction rate.
本文主要研究分析了酵母化学结构与组成,提出了酵母自溶、温差破壁、高压均浆三者相结合的方法来促进酵母内容物溶出提高抽提率,探索抽提率比较高的工艺流程。
The release of intracellular album clastic enzyme resulted in yeast autolysis and the causations of yeast autolysis covered:1.
酵母自溶由酵母胞内蛋白分解酶外泄引起,影响酵母自溶的因素有:(1)酵母菌种;(2)麦汁营养成分组成不合理;(3)酵母使用代数过高;(4)酵母添加量过多;(5)温度、压力、pH值等发酵工艺条件控制不当;(6)酵母回收时间、方法、压力、酵母贮存条件;(7)微生物污染。
