以桔皮为原料,采用超声波进行预处理,然后热回流提取桔皮色素,探讨超声功率、超声温度、超声时间、液料比对色素得率的影响。采用响应面分析法对预处理工艺进行优化。结果表明:超声波预处理能有效的促进桔皮色素提取。在超声功率246 W、超声温度44℃、超声时间21 min、液料比6:1（V:m）的条件下,色素的得率比未经过预处理的试样提高了11.31%。

Pigment of orange peel extracted using ultrasonic pretreatment and hot reflux.The effects of ultrasonic power,ultrasonic pretreatment time,temperature and material-liquid ratio on the pigment yield were discussed.The ultrasonic pretreatment process was optimized and analyzed with response surface methodology,and quadratic regression model was founded.The results showed that ultrasonic pretreatment could promote pigment extraction,increase pigment yield.The pigment yield was as 65.53%,which had been increased 11.31% compared with the sample whic...
