The Continuous Determination of Propionate in Food by Headspace and Auto Injection Gas Chromatography

Abstract

Abstract: In this paper, after the sample was acidifyed, propionate was transformed into propanoic acid. The propanoic acid was determinated by Headspace and Auto Injection Gas Chromatography Outstandard quantification. This method was simple and exact. It could continuously determine a great deal of samples at the same time. The method could satisfy the demand on the determination of propanoic acid in import and export food.

Key words: Propionate , Headspace gas chromatography , Auto - injection , Food
