| 摘 要： | 采用CO2超临界萃取法和60％酒精热浸提法提取丢糟中的酯类物质，气相色谱分析结果表明：①两种方法均未能提取丢糟中的乙酸乙酯；②CO2超临界萃取法能够提取丢糟中的乳酸乙酯、己酸乙酯、丁酸乙酯和戊酸乙酯，而酒精热浸提法只能提取出乳酸乙酯和戊酸乙酯，且后者乳酸乙酯的含量达275．9285mg／100g，远远超过了前者的11．8955mg／100g。因此，提取丢糟中主要酯类成分，CO2超临界萃取法优于60％（v／v）酒精热浸提法。

| Abstract: | CO2 supercritical extraction and 60 %(v/v) alcohol hot lixiviation were used respectively for esters extraction from spent grains. The gas chromatography analysis indicated that both the two methods could not extract ethyl acetate from spent grains, CO2 supercritical extraction could extract ethyl lactate (content 11.8955 mg/100 g), ethyl caproate, ethyl butyrate and ethyl pentanoate, however, alcohol hot lixiviation could only extract ethyl lactate (content 275.9285 mg/100 g) and ethyl pentanoate. Accordingly, CO2 supercritical extraction used for the extraction of mains esters from spent grains was obviously better than 60 %(v/v) alcohol hot lixiviation. |
