Natural pigment discoloration prevention composition {PREVENTIVE COMPOSITION OF COLOR CHANGE FOR NATURAL PIGMENT}

The present invention relates to a natural pigment discoloration prevention composition, and more particularly, to prevent discoloration of natural pigments, which has an excellent effect in preventing discoloration of natural pigments such as vegetable dyes or microbial pigments, which can greatly contribute to color stability of products containing natural pigments. It relates to a composition.

A pigment is a substance added to make a product's color. Such pigments can be roughly divided into synthetic pigments and natural pigments.

Conventional pigments have been used a lot because artificial synthetic dyes, commonly called tar dyes, are cheaper and more stable than natural dyes in terms of price and stability. However, artificial dyes, especially tar dyes, are synthesized as dyes of original fabrics, and the amount of harmful ingredients is strictly regulated.

For this reason, in recent years, the use of natural pigments such as vegetable dyes and microbial pigments is increasing in countries around the world, rather than the use of synthetic pigments in various foods and cosmetic products, but natural pigments are easily discolored or discolored during processing or preservation. It is very difficult to keep the war color intact, and in some cases, it may damage the value of the product.

Therefore, in order to develop a product by applying a natural pigment that is not harmful to the human body, it is necessary to develop a discoloration preventing composition that can prevent discoloration of the natural pigment.

In order to solve the problems of the prior art as described above, an object of the present invention is to provide a discoloration preventing composition of a natural pigment, a dyeing method and a product using the same, which is harmless to the human body and excellent in discoloring preventing effects on natural pigment.
