Food coloring for food additives
Good food pays attention to color, aroma, taste, and wholeness. "Color" is people's first impression of food, good color can promote people's appetite, increase the secretion of digestive juices, so it is conducive to digestion and absorption, is an important sensory indicator of food. Therefore, in order to better improve the color of food, food companies usually add "food coloring" in the food processing process.

"Food coloring" is a kind of food additive also called "colorant", which can be divided into two categories: synthetic food coloring and natural food coloring.
Natural pigments mainly refer to pigments extracted from animal and plant tissues, mostly plant pigments, including microbial pigments, animal pigments and inorganic pigments. The advantage is high safety, and some also have a nutritional effect. However, the disadvantages of natural pigments are higher cost, short shelf life, complex technology in extraction and impurity removal, many instabilities and difficulty in being absorbed by the human body.
The raw materials of synthetic pigments are mainly chemical products, and organic pigments are obtained through chemical synthesis.
Compared with natural pigments, the color is more vivid, not easy to fade, and the advantages of lower price are more favored by the market and widely used.
In life, we seem to be more and more places where we need food coloring, and everyone is very worried about whether synthetic pigments are harmful to the body.
The first thing we want to make clear is that synthetic pigments that meet the standards are allowed to be added in China's "Food Additive Use Standards" (GB 2760-2014), and all food additives listed in the "Food Additives Use Standards" are safe and reliable and necessary according to regulations.
But at the same time, long-term unreasonable food synthetic pigments do have an impact on the human body, mainly reflected in three aspects: general toxicity, diarrhea and carcinogenicity. In addition, many food synthetic pigments may also be mixed with toxic intermediates such as arsenic and lead during the production process.
Because of this, China has strict regulations for edible synthetic pigments, such as: to strictly stipulate the types, purity, specifications, dosages, and allowable foods of edible synthetic pigments.
The picture shows the partial range and maximum use of synthetic pigments (erythrosite and its aluminum lake) stipulated by the state
In fact, whether it is natural food coloring or synthetic food coloring, its safety must stand on the same starting line for risk assessment. As long as it is passed through risk assessment, approved and used in accordance with the standard provisions and the corresponding quality specifications, it is safe and will not cause harm to the health of consumers.
Therefore, whether it is natural food coloring or synthetic food coloring is not terrible. The terrible thing is that black heart manufacturers use industrial dyes instead of edibles to endanger our health.
In the process of purchasing, we should not excessively pursue the sensory characteristics of food, and purchase food produced by regular manufacturers through formal channels.
