Abstract:１．７５％ＮａＣｌ溶液可有效抽提林木毛霉菌丝体表面的蛋白酶，依此确立了腐乳毛坯中蛋白酶的检测法。该酶系在４０％以下２ｈ酶活稳定不变，６０℃ｌｈ能保持５８％活力；其最适作用温度和ｐＨ分别为５５～６０℃和６～７ｐＨ；ｐＨ稳定范围为４～７；ＮａＣｌ和ＣＨ＿３ＣＨ＿２ＯＨ对酶系有明显的保护作用。讨论了蛋白酶检测及其性质对腐乳工艺改进的指导意义。

Abstract:从毛霉ＭｕｃｏｒＺ３ｌ８出发，选育出Ｍ．Ｚ３２８变异株。研究了Ｍ．Ｚ３２８变异株的前酵条件：Ｔ＝３０±１℃，相对湿度９５％．采用新工艺进行生产实验，前酵时间仅需２２ｈ．首次发现毛霉菌丝能渗透到豆腐坯的最深层。用正交试验确定后酵条件。优化结果表明，采用低盐控温后酵新工艺，能将后酵时间缩短到１０～１２ｄ，即可生产出氨基酸态氮高达１．７５ｇ／１００ｇ干腐乳以上的白腐乳。其质构、颜色等均能达到质量要求。研究了腐乳发酵过程的流变特性，微细结构及ＤＳＣ．图谱的变化情况。
