Red40 Ingredients
On the composition of Red Forty
Red Forty is a genus of food colorants. Its composition is related to the beauty of chemical synthesis.
The raw material of Red Forty is derived from coal tar extract. After complex chemical processes, various organic compounds interact. Among them, specific aromatic hydrocarbons undergo multiple reactions, add suitable chemical reagents, and apply precise temperature and pressure regulation to obtain the basic ingredients of this colorant.
This colorant contains several complex organic molecular structures. Its core part has a conjugated double bond system, which gives it a bright red characteristic. And around the molecule, there are specific functional groups, such as sulfonic acid groups, etc. Such functional groups not only affect its solubility, but can be evenly dispersed in aqueous solution to achieve good coloring effect, but also play a role in its stability, so that it can maintain the constant color within a certain acid-base and temperature range.
In the preparation process of Red Forty, the purity requirements are very high. It needs to be purified layer by layer to remove impurities and ensure its quality and safety. Because it is used in food, medicine and other fields, tiny impurities may pose a potential danger to human health. Therefore, the control of its ingredients and the rigorous preparation process are essential.
