Good evening. Some synthetic pigments are indeed synthesized from aniline dyes. We used to call it saccharin pigment here. Synthetic food pigment belongs to a small amount of non-toxic and a large amount of micro-toxic, which you can understand as the toxicity of ethanol relative to liquor. Cabbage red, carmine, lemon yellow, sunset yellow, etc. All fall into this category. The CMYK of common edible ink-jet printing ink is aniline (C: brilliant blue, M: cabbage red +30% scarlet. Y: lemon yellow, k: pure black, also called edible carbon black, cola black). However, it is different from aniline dyes used in ordinary inkjet printer dyes. After purification and impurity removal, the national GB standard stipulates the consumption. Generally, the purity of artificial edible pigments you buy in the market is very low. If you look closely, you will find that they are all mixed with very little pigment, such as edible salt such as sodium chloride. Adding 0. 1%-0.5% will have a very bright dyeing effect. Are you interested in this pigment?
