Food pigment rapid detection instrument

The pigment detector can quickly and quantitatively detect the content of artificially synthesized pigments such as lemon yellow, sunset yellow, carmine red, amaranth red, allure red, bright blue, and erythrin in food.

At present, the synthetic pigments allowed to be used in China include amaranth, carmine, lemon yellow, sunset yellow, and indigo. They are respectively used for fruit flavored water, fruit flavored powder, fruit dew, soda, prepared wine, red and green silk, canned food, and surface coloring of pastries. These synthetic pigments do make the surface of food look particularly appealing, but they are prohibited from being used in the following foods: meat and its processed products (including visceral processed products), fish and its processed products, fruits and their products (including juice, preserved fruits, jam, jelly, and brewed fruit wine), seasonings, baby food, biscuits, etc.
