摘  要:
采用Plackett-Burman法对影响丹贝发酵因素的效应进行评价,并获得了三个因素具有显著影响效应:面粉添加量、乳酸添加量、发酵时间;然后利用最陡爬坡实验逼近最大响应区域,采用响应面分析法对影响丹贝固态发酵的三个主要因素进行研究,建立了影响因素与响应值之间的回归方程,根据回归方程获得最佳发酵条件:面粉添加量1.9%、乳酸添加量1.0%、发酵时间为19.4h。

摘  要:
Plackett-Burman design was used to evaluate the effective degree of factors on tempeh fermentation.The results showed that the amount of flour powder,lactic acid and fermentation time were most effective.Then the response surface analysis(uniform precision of central composite design,SAS 9.0 software)was applied to optimize three major factors for tempeh solid fermentation.The steepest accent experiment was used to approach the optimal conditions subsequently.The equation of polynomial regression was established between those factors and the response.The optimum conditions were made sure as follows:flower powder was 1.9%,lactic acid was 1%,and fermentation time was 19.4h.
