| 摘 要： | 采用响应面法对酱油曲霉固体发酵芝麻饼粕提高抗氧化能力的条件进行优化。通过Plackett-Burman设计法,评价麦芽糖、葡萄糖、蔗糖、果糖、麦麸、玉米浆、酵母膏和硫酸铵8个因素对清除DPPH自由基能力的影响。筛选出麦麸、葡萄糖和硫酸铵为影响芝麻饼粕发酵提取物抗氧化活性的3个显著因素,然后采用中心组合试验设计和响应面分析法,对3个关键因素进行优化。优化的发酵条件为:葡萄糖、硫酸铵和麦麸添加量分别为1.87%、1.54%和2.55%。在该实验条件下,DPPH自由基清除活性为80.26%。

| Abstract: | Response surface methodology was used to optimize fermentation condition to improve antioxidant activity in solidstate sesame cake by Aspergillus sojae.The effects of maltose,glucose,sucrose,fructose,wheat bran,corn steep,yeast extract and ammonium sulfate on scavenging capability of sesame cake to DPPH free radicals were evaluated by using Plackett-Burman design.Results showed that wheat bran and glucose as well as ammonium sulfate were the major factors and had significant effect on antioxidant activity.M... |
