Study on Strains Screening and Fermentation Conditions for Enhance Feed Quality of Sesame Meal
摘要
Abstract
Single factor and orthogonal experiment was used to optimize the fermentation condition to reduce the phytase content and increase the beneficial content such as crude protein and acid insoluble protein in the sesame meal. Sesame meal was used as raw materials to ferment with Bacillus Subtilis, LactobaciUus, and Saccharomycetes. The conditions for single factor experiment were as follows ： the ratio of material to water was 1 ： 0.8 （ g： mL） , the addi- tive amount of phytase was 0.20% , bacteria R - 02 and KG - 109 was mixed fermented. And the optimal fermenta-tion conditions obtained via orthogonal test were as follows： the temperature was 30℃ , the inoculation proportion of R-02 to KG - 109 was 2： 1, the inoculation percentage was 8% and the fermentation time was 10 day. Under these fermentation conditions, the content and degradation rate of phytic acid were 0.08% and 86.21% , respectively. The content of crude protein, acid insoluble protein, and volatile basic nitrogen were 49.85% , 9.07% and 207.55 nag/ 100g, respectively.关键词
