Food Dyes

Food dye, also known as food pigment, is mainly used for food coloring, it must comply with the provisions of the National Food Hygiene Law, itself must be non-toxic, and can not contain any heavy metals and toxic impurities, will not produce any toxic substances in the organism. Mainly used in food, medicine and cosmetics industry coloring. It can be divided into two categories: natural and synthetic. Natural food pigment refers to the pigment substance in natural food. The pigment extracted from animal, plant and microbial raw materials is called natural food pigment, and the common ones are carotene, beet red and so on. Synthetic food pigment is a kind of pigment which can be used in food coloring by chemical method. There are many kinds of pigment, but there are not many safe and non-toxic ones used in food coloring. Synthetic food dyes will be more bright than natural pigments, more tonal, not easy to fade and low price, and its performance is stable, strong coloring power, easy to use, but its dosage and scope of use are greatly limited. and a large number of studies have pointed out that almost all synthetic pigments will not provide the necessary nutrients to the human body, and some will even be harmful to human health.

At present, the synthesized edible dyes are edible lemon yellow, edible orange, edible carmine, edible amaranth, edible indigo, edible bright blue and so on.
