Synthetic colorants in food

Food colorants are additives with the main purpose of coloring food, also known as food pigments. Food colorants give food a pleasing color, which is of great significance in increasing food preferences and stimulating appetite

According to their sources, they can be divided into artificially synthesized colorants and natural colorants. The main raw materials for synthesizing colorants are chemical products. Commonly used natural colorants include chili red, beet red, monascus red, carmine red, sorghum red, sodium copper chlorophyllin, turmeric, gardenia yellow, carotene, phycocyanin, cocoa pigment, caramel pigment, and so on. The color of natural colorants is easily affected by metal ions, water quality, pH value, oxidation, light, and temperature, and is generally difficult to disperse. The dyeing ability and solubility between colorants are poor, and the price is relatively high. Edible natural colorants mainly refer to pigments extracted from animal and plant tissues, mostly plant pigments, including microbial pigments, animal pigments, and inorganic pigments. According to structure, artificially synthesized colorants can also be classified as azo, anthracene, and diphenylmethane; Natural colorants can also be divided into pyrrole, polyene, ketone, quinone, and polyphenol types. According to the solubility of colorants, they can be divided into lipid soluble colorants and water-soluble colorants
