摘  要:
用少孢根霉GIM3.381发酵腐乳,以蛋白酶活力为表征指标,通过单因素及正交实验分析得前酵最佳工艺为:温度20℃,时间48h,pH2.5,接种量10%(孢子悬液);发酵全程腐乳坯质构变化为:硬度先增后减,黏着性逐渐升高,弹性逐渐降低;后酵50d,水分、氨基酸态氮和氯化钠含量为66.1%、1.76g/100g和8.9g/100g,达腐乳成熟标准。

摘  要:
Fermenting sufu by Rhizopus oligosporus Saito GIM3.381. The protease activity as typical,the single factor and the orthogonal experiment analysis of optimum of fermentation:fermentation temperature 20℃,time48 h,pH2.5,inoculating amount 10%(spore suspension). In the fermentation process,sufu pehtze hardness increase first and then decrease,adhesion increased gradually,elasticity reduces gradually. The fiftieth day in the period of after-fermentation,the contents of water,amino acid nitrogen and aodium chloride were 66.1%,1.76g/100 and 8.9g/100 g,reaching the mature standard.
