摘要: 以45 ℃下烘干的柠檬皮渣为原料,采用超声波辅助乙醇提取其中的苦素类物质,考察了乙醇浓度、液固比、超声波处理时间对提取率的影响。运用响应曲面法设计实验方案,建模分析得到柠檬苦素提取最优工艺条件,即乙醇浓度70%、液固比15、处理时间35 min。此条件下,苦素平均提取率达1.721 mg/g,而且实验的重现性好,可望为柠檬苦素的提取与利用提供参考。

Abstract: In this study,45 oC dried lemon peel was used as raw material to extract the bitter element by ultrasonication using ethanol as extraction solvent.The effects of ethanol concentration,liquid solid ratio and ultrasonic treatment time on the extraction yield of bitter element were studied.The response surface methodology was used to design experimental program.The optimized extraction conditions were obtained as follows:the ethanol concentration was 70%,liquid solid ratio was 15:1 and ultrasonic treatment time was 35min.Under these conditions,the average extraction yield of bitter element was determined to be 1.721 mg/g with good reproducibility.The results of this study provided reference data for the extraction and utilization of limonin.

Key words: limonin, lemon peel, response surface methodology, ultrasonic extraction
