采用微生物发酵法对亚麻饼粕进行脱毒。选用L9(34)正交实验,确定微生物发酵条件为:酿酒酵母Saccharomyces cerevisiae CICC 31077,接种量为3%,含水量为50%,发酵温度28℃,发酵时间72 h,在此条件下,生氰糖苷脱除率为76.91%。

The microbial fermentation methods were employed to detoxify flaxseeds.The L9(34) orthogonal array was adopted in the experiment.The results showed that the optimum parameters were as follows: Saccharomyces cerevisiae,CICC 31077,fermentation time was 72h,inoculation amount was 3%,fluid-solid was 50%,and fermentation temperature was 28℃.The degradability of cyanogenic glycosides was 76.91% under these conditions.It was propitious to exploit linseed meal for functional food.
