中文摘要: 为探讨超声波辅助法提取香水柠檬果皮绿色素的最佳工艺条件，以废弃的香水柠檬果皮为原料，以绿色素溶液吸光度为响应值，采用Box-Behnken响应面分析法优化绿色素的提取工艺，并观察温度、光照、山梨酸等8种食品添加剂和金属离子对提取绿色素稳定性的影响。结果表明，香水柠檬果皮绿色素最佳提取条件为：提取时间75 min，提取功率640 W，乙醇体积分数80%，液料比31∶1（mL/g）条件下，提取的绿色素吸光度均值为0.459。香水柠檬果皮中的绿色素不耐高温和长时间光照，部分金属离子可影响其稳定性，但食品添加剂对其稳定性无显著影响。
Abstract:In order to optimize the extraction process of green pigment from Citrus Limon（L.Burm.F.）peel，the Citrus Limon（L.Burm.F.）peel was used as raw material，the absorbance of green pigment solution was taken as the response value，and the optimal process of green pigment was optimized by Box-Behnken response surface analysis method.Then the effects of temperature，light，sorbic acid and other eight kinds of food additives，and metal ions on the stability of extracting green pigment were observed.Results showed that the extraction conditions of green pigment from Citrus Limon （L.Burm.F.）peel were as follow：extraction time was 75 min，extraction power was 640 W，ethanol concentration was 80%and liquid-solid ratio was 31 ∶1（mL/g）.The absorbance of green pigment extract was 0.459.The stability was affected by temperature，light and some metal ions；but it was not affected by food additives.
