Food coloring, an edible dye used as a food additive to improve the appearance of an item. It is often used for the dyeing of processed food products, beverages, drugs, lipsticks and cosmetics.
Food coloring is a kind of pigment, that is, a food additive that can be eaten in an appropriate amount that can make the food change the original color to a certain extent. Food coloring is also the same as food flavors, divided into natural and synthetic two types.

However, natural foods are easy to fade or change color during processing and preservation, in order to improve the color of food, people often add food coloring in the process of processing food to improve sensory properties.
The synthetic pigments listed in the sanitary standards (GB2760-1996) for food additives in China are annatto, amaranth red, sunset yellow, red moss red, lemon yellow, new red, indigo, bright blue, titanium dioxide (white pigment) and so on.
