摘要
采用超声波法提取山竹果壳色素,并通过L(934)正交试验优化提取工艺条件。结果表明:色素在可见光区的最大吸收波长为478 nm,最佳提取工艺条件为:以70%乙醇为浸提剂,超声波功率350 W,提取时间40 min,料液比1∶30(g/mL),提取温度70℃,此条件下的色素提取液吸光度值A478为2.26。超声波辅助提取山竹果壳色素的效率明显高于常规提取法。
Extraction experiments of mangosteen pigment by ultrasonic was explored, and process conditions through L9 （34） orthogonal test was optimized in this paper. Results showed that the maximum absorption wave length of pigment was 478 nm; the optimal extraction conditions were as follows, ultrasonic power 350 W, temperature 70℃, extraction time 40 rain, ratio of liquid to solid 1 ： 30 （g/mL） with 70 % ethanol（volume ratio） as extraction solution; the A 478nm absorbance value was 2.26 under this condition. Meanwhile, extraction efficiency of mangosteen shell pigment assisted with ultrasonic was obviously superior to conventional extraction method.
