For example, Hami melon milk tea, papaya milk tea and so on. Sometimes the store will add some colorful preserved fruits, pulp and other raw materials to the milk tea, which is very popular with young people.
However, the auxiliary materials used in this kind of fruit milk tea are not real fruits, but raw materials called "fruit powder". All kinds of preserved fruits and pulp are also processed products, and pigments and other ingredients have been added.
"In addition to white candied fruit, other colors of candied fruit are formed by adding pigments, such as sunset yellow and carmine, but after drinking one or two glasses of this kind of thing, the human body will not feel any different."
Ying Tiejin, a professor in the Department of Food Science and Nutrition, College of Agriculture, Industry and Food, Zhejiang University, said that sunset yellow is an artificial pigment, which can be used in high-sugar juice drinks, carbonated drinks and concentrated juice. According to the regulations, the maximum dose is 0.65438 0 g/kg.
Of course, if these synthetic sunset yellow pigments exceed the standard in the process of addition, their toxicity mainly shows general toxicity, drainage and carcinogenicity because of the long incubation period of aniline raw materials.
