摘　　要：以玉米皮为原料,采用微波协同酶法提取玉米黄色素,并对其工艺进行优化。通过单因素试验和正交试验,确定微波协同酶法提取的最佳工艺条件为微波功率400W、微波辐射时间50s、料液比1:8(g/mL)、纤维素酶用量1.2%、酶解温度50℃、酶解时间90min、酶解体系pH5.5。One-factor-at-a-time and orthogonal array design methods were applied to optimize the extraction of yellow pigment from corn bran by cellulase hydrolysis followed by microwave treatment.The optimal extraction conditions were obtained as follows：95% acidified ethanol at pH 5.5 as extraction solvent at a material/liquid ratio of 1：8（g/mL）,and 400 W microwave irradiation for 50 s before cellulase hydrolysis at 50 ℃ for 90 min.
