中文摘要: 研究了 HPLC 方法测定火腿肠中山梨酸、苯甲酸含量时影响山梨酸、苯甲酸提取的 3 个主要因素:超声时 间、沉淀剂用量和料液比。并通过单因素和正交试验得到火腿肠中山梨酸、苯甲酸提取的最优工艺条件。当超声时间 为 15 min、亚铁氰化钾和乙酸锌各添加 3 mL、料液比为 1 ∶ 11(g/mL)时提取效果最好。数据表明该方法线性关系相关 系数良好(0.999 9~1.000 0),平均加标回收率均在 90 %以上,简化了预处理过程,具有检测速度快、灵敏度和准确度 高、自动化程度高等优点。
Abstract:The effects of three main factors on the extraction of sorbic acid and benzoic acid in HPLC: ultrason- ic time, precipitation agent, and material liquid ratio were studied. By single factor extraction tests and the or- thogonal tests the optimum extracting conditions for sorbic acid and benzoic acid in ham sausage were confirmed as follows: the ultrasonic time 15 min, added potassium ferrocyanide and zinc acetate each for 3 mL as precipi- tant, liquid material ratio 1 ∶ 11(g/mL). The results showed that the method had good linear correlation coeffi- cient (0.999 9-1.000 0), and the average recovery rate of the method was more than 90 %, which had the ad- vantages of simple, fast detection, high sensitivity, high accuracy, and high automation degree.
