Natural pigment properties

- Sep 08, 2018-

Natural pigments are generally derived from natural ingredients such as beet red, grapes and peppers. These foods have been recognized and accepted by consumers. Therefore, natural pigments derived from these food sources are more popular with consumers and are used more. Safer. Most are derived from plant pigments.

Some products use artificial pigments to reduce the appearance of artificial factors and are therefore closer to the natural form, thus attracting more consumers. Nowadays in the European Union, natural pigments not only seize the market for synthetic pigments, but also seize the market for some pigment extracts.

Most plant pigments have no side effects and are highly safe. Most of the plant pigments are anthocyanins, carotenoids, and flavonoids. They are a class of biologically active substances and are functional active ingredients in botanicals and health foods. In view of the fact that plant pigments are used as additives for coloring in foods, pharmaceuticals, and cosmetics, the amount of therapeutic use does not reach the dose-effective ratio of medical and health care products. In the application of health foods, this kind of plant pigments can play an auxiliary role in enhancing human immune function, anti-oxidation and lowering blood lipids; in common foods, some can play the auxiliary role of nutrition strengthening and anti-oxidation.

The coloration of plant pigments is more natural, which increases the color tone and is similar to natural color. It is a natural beauty. The plant pigment content is less in the plant body, and it is difficult to separate and purify. Some of the coexisting materials may also generate odor when present, so the production cost is higher than that of the synthetic pigment. Most plant pigments are sensitive to light, heat, oxygen, microbial and metal ions and pH changes, and have poor stability. Some plant pigments must be added with oxidants and stabilizers to increase the life cycle of the products. Most of the plant pigments have poor dyeing power, are not easily dyed, and are not bright and bright with synthetic pigments. There are many kinds of plant pigments, and their properties are complex. In terms of a plant pigment, the application is more specific and the application range has certain limitations.
