食品中糖精钠的测定,是食品卫生监督的重要项目之一。目前测定方法一般采用萃取、薄层分离后紫外分光光度法或液相色谱法测定,但存在着分析手续烦琐、流程冗长和仪器昂贵之缺点。利用糖精电极测定饮料中的糖精钠具有操作简便、仪器配套简单等优点,有利于普遍推广。国外虽有糖精电极研制报道,但其灵敏度和选择性较差,未见实际应用;国内近年来已研制成功性能良好的糖精电极,并开展了某些应用,但由于食品种类繁多,且随食品种类之不
Determination of sodium saccharin in food, is one of the important items of food hygiene supervision. At present, the determination method generally adopts the method of extraction, thin layer separation after UV spectrophotometry or liquid chromatography, but there are disadvantages of cumbersome procedures, lengthy procedures and expensive instruments. The use of saccharin electrode in the determination of saccharin sodium beverage has the advantages of simple operation, simple equipment, etc., is conducive to universal promotion. Although saccharin electrode has been reported in foreign countries, its sensitivity and selectivity are poor, but it has not been applied in practice. In recent years, sucrose electrodes with good performance have been developed in China and some applications have been developed. However, due to the wide variety of foods, The kind of not
