超声波辅助提取黑花生蛋白和色素工艺研究

Study on Ultrasonic-assisted Extraction Technology of Protein and Pigment from Black Peanut

以黑花生为原料,采用单因素试验和正交试验方法获取超声波辅助提取黑花生中的蛋白质和色素的最佳工艺条件。试验结果表明:最佳提取条件为超声波功率84 W、温度45℃、料液比1∶9、提取时间80 min;在该工艺条件下,黑花生蛋白质的提取率为29.25%,色素含量为5.75 mg/g。

Taken black peanut as raw material,the optimum technological conditions for extracting the protein and pigment from black peanut were obtained by ultrasonic-assisted technology,by using the methods of single factor experiment and orthogonal experiment.The results showed that the optimum extraction conditions of protein and pigment were the ultrasonic power 84 W,the temperature of 45℃,the feed liquid ratio of 1∶9,and extraction time 80 min.Under the technological conditions,the yield of black peanut protein was 29.25%,and the pigment content was 5.75 mg/g.
