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
甜菜紅色素是一種水溶性含氮類色素,主要存在于紅甜菜(俗稱紫菜頭)、商陸、火龍果、紫茉莉、雞冠花及仙人掌屬的某些植物體中,是優(yōu)良的食用紅色色素和黃色色素來源[1]。(剩余6219字)
