A kind of natural pigment composition and its application of replacing synthetic pigment

Abstract

The invention relates to the field of natural pigments, and particularly discloses natural pigment compositions instead of a synthetic pigment and an application thereof. The natural pigment compositions are prepared by compounding gardenia yellow respectively with xanthophyll, monascus yellow and beta-carotene. The natural pigments which can replace the synthetic pigment lemon yellow applied to the tobacco thin sheet field are obtained by starting from the natural pigment and then compounding with various suitable-type natural pigments, and at the same time, the demand of people on safety and original tones is met.

Description

technical field [0001] The invention relates to the field of natural pigments, in particular to a natural pigment composition for replacing synthetic pigments and its application. Background technique [0002] Synthetic pigments tartrazine, sunset yellow, carmine, allura red, and fruit green are widely used coloring agents in the tobacco industry, especially in tobacco flakes. These kinds of synthetic pigments are organic pigments prepared by artificial chemical synthesis methods, mainly based on aniline dyes separated from coal tar as raw materials. The hazards to the human body include general toxicity, diarrhea, mutagenicity (gene mutation) and carcinogenicity. [0003] With the development of society and the improvement of people's living standards, more and more people have questioned whether the use of synthetic pigments will cause harm to human health. At the same time, a large number of research reports point out that almost all synthetic pigments cannot provide nu...

AI Technical Summary

Problems solved by technology

At the same time, a large number of research reports point out that almost all synthetic pigments cannot provide nutrients to the human body, and some synthetic pigments may even endanger human health.

Researchers in the United States, Britain and other countries have also found after doing relevant research that many synthetic pigments have harmful effects on the human body, which may lead to fertility decline, teratogenicity, etc. Some pigments may be converted into carcinogens in the human body, especially The carcinogenic effect of azo compound synthetic pigments is more obvious

In addition, in addition to being toxic itself or its metabolites, many food synthetic pigments may also be mixed with arsenic and lead during the production process
