What is LACCAIC ACID?

LACCAIC ACID is one of the most widely used natural colors, it is an extract derived from animals. People’s utilization of lac red pigment is earlier than that of lac resin. Lac red pigment is traditionally used in food, medicine, cosmetics, printing and dyeing and textile industries. Its color itself is red or pink, but it is formulated through mordant dyeing. Other shades available.

In recent years, with the development of medical toxicology and biological experiments, people have realized that some synthetic food colorings have certain toxicity to the human body, and some have carcinogenic effects. Therefore, natural coloring has gained widespread attention and application again. . LACCAIC ACID is water-soluble and non-toxic, and has been widely used as an additive with high safety. Moreover, lac red pigment has stronger tinting power than other natural pigments, and has good stability to light, metal ions and heat, etc. Advantages, lac red pigment is increasingly accepted as a natural food coloring. Japan and other countries have dyed food with lac red pigment, and its application prospect is very broad.
