Determination of Preservative and Sweetener in Sugar by Reverse-Phase HPLC
摘要
Abstract
Reverse-phase HPLC was applied to the determination of benzoic acid, sorbic acid, dehydroacetic acid, acesulfame K, sodium saccharin in sugar. The analysis column was Venusil XBP - C18 (5 μm, 4.6×250 mm), the mobile phase was Methanol - 20 mmol/L NHgAc, the flow rate was 1.0 mL/min. The column temperature was 30 ℃, and the injection volume was 10 μL. The limit of quantitation was 1.0 mg/L. The linear plots were obtained between 10 and 100 mg/L. Overall recoveries were between 89.85% and 103.60%, and RSD (n = 4) value were 1.50% and 3.26%. Results showed this method was simple and accurate, it could be applied for determination of preservative and sweetener in sugar.关键词
