Method for preparing colorant having target color and colorant

Abstract

The invention relates to a method of preparing a colorant having a target color and the colorant. The method comprises the steps: configuring the diameters of submicron particles prepared from a predetermined material into a predetermined size; adjusting the ratio of the submicron particles prepared from the predetermined material to the submicron particles of cuttlefish ink to a predetermined ratio; evaporating a predetermined solution in which the submicron particles prepared by mixing the predetermined material and the cuttlefish ink submicron particles are mixed, so as to self-assemble the submicron particles into an amorphous photonic crystal structure; acquiring spectral data formed by reflected light generated when incident light irradiates an amorphous photonic crystal structure; determining whether the spectral data meets a predetermined condition; and if it is determined that the spectral data does not meet the predetermined condition, adjusting at least one of the proportion and the size of the submicron particles prepared from the predetermined material until the spectral data meet the predetermined condition, and generating the colorant with the target color based on the amorphous photonic crystal structure. The color development stability of the colorant can be improved, and free regulation and control of the color can be realized.

Description

technical field [0001] The present disclosure relates generally to the preparation of colorants, and in particular, to methods for preparing colorants having a target color and colorants having a target color. Background technique [0002] Traditional colorants (such as but not limited to edible colorants) are generally divided into two categories, one is natural colorants, and the second is artificially synthesized colorants. The above-mentioned natural colorants are often sensitive to changes in factors such as light, pH, and temperature, thus causing the color of the colorant to be unstable, and the color is likely to change or even fade. The traditional method of preparing synthetic colorants, such as organic colorants prepared by artificial chemical synthesis, is mainly made of aniline dyes separated from coal tar as raw materials. Although artificially synthesized colorants have the advantages of mature synthesis process, stable coloring, and low cost, the above-menti...

AI Technical Summary

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
