FREE SAMPLE TEST Ponceau 4R Carmine 60 Red Edible Pigment

    Coloring agents, also known as pigments, are a class of substances that enhance the sensory properties of foods after they are colored. According to their nature and source, food coloring can be divided into two categories: edible natural pigments and edible synthetic pigments.

    1. Edible synthetic pigments are artificial synthetic pigments. The characteristics of edible synthetic pigments: bright colors, stable nature, strong tinting strength, high firmness, and can obtain any color, plus low cost and convenient use. However, most synthetic pigments are harmful to humans. The toxicity of synthetic pigments is directly toxic to the human body due to its own chemical properties; some may produce harmful substances in the metabolic process; it may also be contaminated by arsenic, lead or other harmful compounds in the production process. The synthetic pigments currently permitted in China are amaranth, carmine, reddish red (cherry red), new red, tempting red, lemon yellow, sunset yellow, bright blue, indigo and their respective aluminum lakes. And synthetic beta-carotene, copper chlorophyllin and titanium dioxide.

    2. The use of natural pigments, the use of natural pigments is mainly derived from the pigments extracted from animal and plant tissues, the natural pigment components of humans are more complex, and the purified natural pigments may have different effects. Moreover, in the process of refining, the chemical structure may also change; in addition, in the process of processing, there is the possibility of being contaminated, so it cannot be considered that the natural pigment must be pure and harmless. Synthetic food coloring, like other food additives, requires rigorous toxicological evaluation for safe use.
