摘要
采用顶空气相色谱法对青梅果酒中的6种高级醇和4种酯类化合物进行定性定量分析.结果表明五粮液青梅蜜酿中各物质的含量分别为正丙醇1.84 mg·L-1、正丁醇8.87 mg·L-1,正戊醇和仲丁醇未检测到,异丁醇14.12 mg·-1、异戊醇85.30 mg·L-1、乙酸乙酯24.02 mg·L-1、丁酸乙酯0.06 mg·L-1、己酸乙酯0.14 mg·L-1、乳酸乙酯3.07 mg·L-1.该方法操作简单、数据处理方便,且内标法定量保证了方法的可靠性和准确性.
Abstract
Headspace-gas chromatography was applied for qualitative and quantitative analysis of six higher alcohols and four esters in green plum wine.The results showed that the contents of 1-propanol,1-butanol,1-pentanol,2-butanol,2-methyl-1-propanol,3-methyl-1-butanol,ethyl acetate,ethyl butyrate,ethyl hexanoate and ethyl lactate are 1.84 mg·L-1,8.87 mg·L-1,14.12 mg·L-1,85.30 mg·L-1,24.02 mg·L-1 0.06 mg·L-1,0.14 mg·L-1 and 3.07 mg·L-1,respectively.The method is simple,rapid and sensitive,and internal standard method ensures the reliability and accuracy of the method.
