Abstract: This article selects four types of food, namely soda, jelly, candy, and makeup on pastries, as the research objects. High performance liquid chromatography technology is used to establish an inspection method for beet red pigment in food. The established method is validated with specific parameters such as standard curve, detection limit, quantitative limit, recovery rate, and precision, in order to provide scientific basis for the establishment of national food safety detection standards for beet red pigment.
Key words: high performance liquid chromatography; beet red pigment; pH value; recovery rate
甜菜红色素是一种水溶性含氮类色素,主要存在于红甜菜(俗称紫菜头)、商陆、火龙果、紫茉莉、鸡冠花及仙人掌属的某些植物体中,是优良的食用红色色素和黄色色素来源[1]。(剩余6219字)
