摘　　要：为探究熏鸡糖熏上色机理,对糖熏熏鸡皮色素进行提取。对糖熏熏鸡皮色素的提取工艺参数进行优化。以糖熏熏鸡皮为原料,采用超声辅助提取糖熏熏鸡皮色素,以色素溶液的吸光度为指标,通过单因素试验考察乙醇体积分数、超声波处理提取时间、液料比对糖熏熏鸡皮色素提取液吸光度的影响,并结合响应面试验对提取工艺进行优化。结果表明:超声辅助提取糖熏熏鸡皮色素的最佳工艺条件为乙醇体积分数85%、超声波处理提取时间32 min、液料比10∶1(V/m);在最佳工艺参数条件下,实验提取的糖熏熏鸡皮色素的吸光度为3.397,与理论值相差0.38%,表明该色素的提取工艺条件合理可行。In order to explore the mechanism of color formation in sugar-smoked chicken,it is necessary to extract pigment from sugar-smoked chicken skin.The objective of this study was to optimize process parameters for ultrasonic-assisted extraction of pigment from sugar-smoked chicken skin using one-factor-at-a-time method and response surface methodology(RSM).The absorbance of pigment was investigated with respect to three variables,ethanol concentration,ultrasonic time and solid-to-liquid ratio.The use of 85%ethanol as extraction solvent,a solid-to-liquid ratio of 10:1(V/m)and ultrasonic treatment for 32 min were found to be the optimal conditions to obtain a higher absorbance value of 3.397,with only 0.38%deviation as compared to the predicted value.Hence,the optimized extraction process was feasible.
