Problems solved by technology

Although artificially synthesized colorants have the advantages of mature synthesis process, stable coloring, and low cost, the above-mentioned artificial chemical synthesis process is likely to cause environmental pollution. In addition, there are ingredients that are harmful to human health in artificial colorants.
In addition, the color options of the above-mentioned natural colorants and synthetic colorants are limited
[0003] Therefore, the shortcomings of the traditional scheme for preparing colorants are: the color development is unstable, and at the same time, the range of displayed colors is limited
In addition, artificial synthetic colorants have ingredients that are harmful to human health

Abstract

The present disclosure relates to a method of preparing a colorant having a target color and the colorant. The method includes: configuring the diameter of the submicron particles prepared from a predetermined material to a predetermined size; adjusting the ratio of the submicron particles prepared from a predetermined material to the submicron particles of cuttlefish juice to a predetermined ratio; mixing the submicron particles prepared from a predetermined material and The predetermined solution of squid juice submicron particles is evaporated so that the submicron particles self-assemble into an amorphous photonic crystal structure; the spectral data formed by the reflected light generated by the incident light irradiating the amorphous photonic crystal structure is obtained; and it is determined whether the spectral data meet the predetermined conditions and if it is determined that the spectral data does not meet the predetermined conditions, adjusting at least one of the ratio and the size of the submicron particles prepared from the predetermined material until the spectral data meet the predetermined conditions to generate a colorant with a target color based on the amorphous photonic crystal structure . The disclosure can improve the color stability of the colorant, and can realize free regulation of the color.

Description

Technical field [0001] The present disclosure generally relates to the preparation of colorants, and in particular, to the method for preparing a coloring agent having a target color and a coloring agent having a target color. Background technique [0002] A conventional colorant (for example, is not limited to it is an edible coloring agent), is generally divided into two categories, one is a natural colorant, and the second type of colorant is a manual synthesis colorant. The natural colorant is often sensitive to factors such as light, acid-alkalinity and temperature, and thus the color of the colorant is unstable, and it is easy to change the color even fading. The method of preparing a manual synthetic colorant, for example, an organic colorant obtained by artificial chemical synthesis, is mainly made of an aniline dye isolated in coal tar as a raw material. Although artificial synthetic colorants have advantages such as synthetic process, coloring stability, and low cost, t...
