A determination method based on gas chromatography for analysis of organic acids in alfalfa silage
Wang Hongli, Li Chengyun
This article uses the tetramethyl ammonium hydroxide∕methyl iodide for methyl esterification and the method of temperature program ,determine the content of lactic acid, ethanoic acid, propionic acid, butyric acid.The results showed that: This method separation effect is good, various components recovery rate between 97.8%～101.2%,the duplication is good and having high correlation coeficients of 0.999 0 and 0.999 7. Therefore, this would be an ideal way to determinate the organic acids of alfalfa silage.
