利用冠突散囊菌(Eurotium cristatum)对燕麦进行固态发酵,以黄酮含量为考察指标,通过单因素试验和正交试验优化燕麦固态发酵条件,并对燕麦发酵过程中黄酮含量与苯丙氨酸解氨酶活力动态变化的相关性进行分析.结果 表明,冠突散囊菌固态发酵燕麦的最佳发酵条件为发酵温度30℃,基质pH值6.0,接种量0.5％,发酵时间7d,在此最优发酵条件,燕麦黄酮含量最高,为58.13 mg/g,较优化前提高41.06％;黄酮含量的变化与苯丙氨酸解氨酶活性的变化呈显著正相关.通过冠突散囊菌发酵燕麦提高了燕麦生物活性成分,为燕麦再加工提高附加值提供了有力依据.

:The oat was solid-state fermented by Eurotium cristatum. Taking flavones content as evaluation index, the solid-state fermentation conditions of oat were optimized by single factor experiments and orthogonal experiments. The correlation between flavones content and the dynamic change of phenylalanine ammonialyase activity during fermentation of oat was analyzed. The results showed that the optimal fermentation conditions for solid-state fermentation of oat by E. cristatum were fermentation temperature 30 ℃, substrate pH 6.0, inoculum 0.5%, an...
