Problems solved by technology

However, due to the different physical and chemical properties of different natural pigments, it is difficult to achieve arbitrary color deployment
At present, the prior art only discloses green pigment formulated with gardenia blue pigment and gardenia yellow pigment, green pigment formulated with gardenia blue pigment and safflower yellow pigment, and green pigment formulated with gardenia blue pigment and monascus yellow pigment, Moreover, the hue of these green pigments is relatively dim, which is difficult to meet the requirements of use.

Abstract

The invention provides a natural pigment composition. The composition comprises an emulsifier, and two or more than two pigments selected from gardenia yellow pigment, curcumine, carthamin yellow, orange yellow pigment, xanthophylls, riboflavin, capsanthin, monascus red pigment, anattotree orange pigment and gardenia blue pigment. All the above natural pigments can be blended according to an arbitrary ratio to obtain the natural pigment composition with different color systems and different tones, such as yellow, orange, red, green and purple. The natural pigment composition contains the emulsifier, so the composition is uniform and stable. The combination of different natural pigments in the natural pigment composition makes up the defect of single pigments, for example, the light resistance of the natural yellow pigment composition obtained by combining riboflavin and curcumine with poor light resistance with stable gardenia blue pigment is better than that of riboflavin or curcumine, so the use amount is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of natural pigments, in particular to a natural pigment composition and a preparation method thereof. Background technique [0002] Natural pigments refer to pigments obtained from natural resources, mainly pigments extracted from animals, plants or microorganisms. Natural pigments have the advantages of high safety, natural color, etc., and also have certain nutritional effects and pharmacological effects. They have gradually replaced synthetic pigments and become an important part of food additives. [0003] However, natural pigments also have many shortcomings, such as low solubility, not easy to color evenly; low pigment concentration, poor dyeing property; unstable, greatly affected by factors such as pH value, light, and temperature. The combination of natural pigments can not only make up for the shortcomings of single natural pigments such as uneven coloring and poor dyeing, but also produce new hue...
