What is colorant

Introduction: what is colorant? Many people are asking this question Here is a brief introduction about colorant Coloring has many uses, not only in industry, but also in food industry What is colorant? Colorants are mainly divided into pigment and dye Pigment is a colorant which can't be dissolved in common solvent, so in order to obtain ideal colorability, it is necessary to disperse pigment evenly in plastic by mechanical method According to the structure, it can be divided into organic pigment and inorganic pigment Inorganic pigments have good thermal stability, light stability and low price, but their colouring power is relatively poor and their relative density is large; organic pigments have high colouring power, bright color, complete chromatogram and low relative density, but their disadvantages are not as good as inorganic pigments in terms of heat resistance, weather resistance and covering power Dye is an organic compound which can be used in most solvents and dyed plastics It has the advantages of small density, high coloring power and good transparency, but its general molecular structure is small and easy to transfer when coloring Some colorants are used in industry, but some of them are used in food What's the harm of eating too much colorant? In fact, a small amount of colorant does not harm people, but using too much will cause serious harm However, China's food safety detector It can accurately check the safety level of food, so consumers can eat it at ease More food safety knowledge is in Baibai safety net Editor in charge: he xianrob
