摘要:

通过单因素试验确定超声波功率、超声波作用时间、超声波脉冲时间及料液比的适用范围,再利用正交试验法进行工艺优化,得出超声波提取胭脂虫红色素的最佳工艺条件。结果表明,超声波辅助法提取胭脂虫红色素的最佳工艺条件为超声波功率1400W、超声波处理时间12min、脉冲时间(10s,4s)、料液比1:6,提取次数5次,色素得率可达42.08%。

Abstract:

Single-factor and orthogonal array methods were adopted to optimize the ultrasonic extraction of cochineal dye. The optimal conditions for the improved extraction of cochineal dye were determined as follows: ratio of material to solvent 1:6, ultrasonic power 1400 W, ultrasonic treatment time 12 min, pulse on time 10 min, pulse off time 4 min, and extraction number 5. Under these conditions, the yield of cochineal dye was 42.08%.

Key words: cochineal dye, ultrasonic method, extraction
