摘要: 建立了高效液相色谱测定配制酱油中乙酰丙酸的方法,并提出了测定配制酱油中酿造酱油含量(以总氮计)的公式。对测定酱油中乙酰丙酸含量的两种液相色谱法进行了比较,有机酸柱法在线性范围、回收率、精密度和样品前处理的简便性等方面均优于C18柱法。利用计算公式对市售配制酱油中酿造酱油的含量(以总氮计)进行了测定。

Abstract: A method has been developed for the determination of levulinic acid in soy sauce by liquid chromatography, and the formula calculating the content of fermented soy sauce in the blended soy sauce was given. Two methods of liquid chromatography were compared. The ion exchange column method was better than the C18 column method in every aspect including the assay range and recovery and sample preparation. The content of fermented soy sauce in blended soy sauce was analyzed for some commercial products.

Key words: liquid chromatography, levulinic acid, blended soy sauce, fermented soy sauce, proportion
