Is natural coloring safe? What should I pay attention?
Natural pigments are color compounds derived from natural substances, including pigments in plants, animals, and microorganisms. Compared with synthetic food additives, natural pigments have been widely used because of their good quality and low toxicity. However, there are still some issues that need to be paid attention to when using natural pigments. The following will discuss the use of natural pigments from the aspects of safety, stability and other aspects.
The first is about the safety of natural pigments. In general, natural pigments are safer because they are derived from natural substances and do not contain synthetic chemicals. Most natural pigments are considered to be non-toxic or low toxic, especially legal natural pigments, such as carotene, chlorophyll, etc. These natural pigments are widely used in food, medicine and cosmetics and are considered to be relatively safe. However, although the toxicity of natural pigments is low, they still need to be used reasonably to avoid harm to human health.
The second is the stability of natural pigments. Natural pigments are usually more susceptible to light, temperature, oxidation and other factors than synthetic pigments, which may cause the pigment to fade or decompose. Therefore, when using natural pigments, you need to pay attention to the storage conditions, try to avoid exposure to strong light, avoid high temperature environment, in order to maintain the stability and color effect of the pigment. In addition, some natural pigments may change color or deteriorate in acidic or alkaline environment, so pay attention to the regulation of pH in the formula to avoid adverse effects on the pigment.
In addition, there are some other issues to be aware of regarding the use of natural pigments. The first is the choice of pigment. Natural pigments have a variety of colors to choose from, but the stability and applicability of different pigments are also different, and it is necessary to choose suitable pigments according to specific needs. Followed by the amount of control. Although the natural pigment is relatively safe, it is still necessary to control the addition amount and avoid excessive use. At the same time, the use of natural pigments also need to pay attention to its compatibility with other ingredients, to avoid adverse reactions with other ingredients. Understand the source and processing of natural pigments. Because some natural pigments may come from toxic plants or animals, or may be contaminated during processing, it is important to understand the source and processing of natural pigments to ensure their safety.
