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%。

Abstract:

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.

Key words: lac dye, ultrasonic assistance, extraction
