摘要
为高效地获得紫胶红色素,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,得出超声波辅助提取紫胶红色素的最佳工艺条件。结果表明,超声波辅助法提取紫胶红色素的最佳工艺条件为:超声波功率1200W、超声波处理时间18min、频率20kHz、脉冲时间(9s,12s)、料液比1:6(g/mL)。合适的提取次数为3次,浸提率85.15%,色素得率可达0.55%。
In order to effectively extract lac dye under the assistance of ultrasonic,single factor and orthogonal array design methods were used to optimize process parameters including ultrasonic power,extraction time,pulse time and material/liquid ratio. The optimal extraction conditions were determined as follows：material/liquid ratio,1：6; ultrasonic power,1200 W; extraction duration,18 min; frequency,20 kHz; pulse-on time,9 s,pulse-off time,12 s; and extraction number,3. The extraction efficiency was up to 85.15% and the yield of lac dye was 0.55% under the optimal extraction conditions.
