酒中有机酸的种类、含最和构成不同,形成酒的各种风味和品质。适量的有机酸能促进食欲、助消化,益于健康。因而酒中有机酸的分析对酒的品评很有意义。
A HPLC system that makes it possible to accurately and simultanecously quantitate 14 several common organic acids in rice wine.Among the columns that was used in the experiment,C18column was the best.Only after a single Sep-Pak C18pre-column treatmant,the samples can then be analysed.By using the UV 214nm,all the organic acids have higher absorptions,the concentration range that using this method to determine directy the organic acids in beverages is 20 ng/ml-4μg/ml (different with the kinds of organic acids).
