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

At present, the synthetic pigments allowed for use in China include amaranth, carmine, lemon yellow, sunset yellow, and indigo. They are respectively used for fruit flavored water, fruit flavored powder, fruit juice, soda, blended wine, red and green silk, canned food, and coloring on the surface of pastries. These synthetic pigments do indeed make the surface of food 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 juices, dried fruits, jams, fruit jelly, and fruit wine), seasonings, infant and toddler food, cookies, etc.
