以燕麦为基质,利用冠突散囊菌进行燕麦固态发酵,通过单因素试验和正交试验优化阿魏酸提取工艺及燕麦发酵条件,采用高效液相色谱（HPLC）法测定燕麦的阿魏酸含量。结果表明,阿魏酸提取最佳工艺是采用固液比为1∶10（g∶mL）的体积分数60%的乙醇在50℃条件下浸提发酵燕麦6 h;燕麦发酵最佳条件为裸燕麦在pH 5的水溶液中浸泡12 h,121℃灭菌后接种1%的冠突散囊菌,26℃恒温发酵;在此条件下发酵燕麦阿魏酸含量在发酵第4 d时达到最高835.89μg/g,是未发酵燕麦的4.2倍。

Using oat as the matrix, the oat was fermented by Eurotium cristatum with solid-state fermentation, the ferulic acid extraction process and oat fermentation process were optimized by single factor and orthogonal experiments, and the content of ferulic acid was determined by HPLC. The results showed that the optimal extraction process of ferulic acid was solid-liquid ratio 1∶10（g∶ml）, ethanol concentration 60%, extraction temperature50 ℃, and fermentation time 6 h. The optimal fermentation conditions of oat were as follows： naked oat was s...
