A high performance liquid chromatographic(HPLC) method for the simultaneous determination of acesulfame, benzoic acid, sorbic acid, saccharin sodium and dehydroacetic acid in jelly was developed. Five kinds of additives in jelly were determinated simultaneously through HPLC after having been dissolved, centrifugalled and filtered. Methods:five kinds of additives were separated on a C18 column with mobile phase 0.02 mol/L NH4Ac/methanol(90:10) and column temperature 25℃, lastly the determination was conducted at 230 nm through a photo-diode array detector. The standard addition recovery rate of these samples was 98.7%~100.4%, and the value of RSD was 0.9%~3.0%. The method is simple and accurate, and suitable for routine testing of five kinds of additives in jelly.
