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.

preparation example Construction

[0046] The present invention also provides a preparation method of natural pigment composition, comprising:

[0047] a) Dissolving and mixing two or more natural pigments respectively, the natural pigments are gardenia yellow pigment, curcumin, safflower yellow pigment, capsanthin, monascus red pigment, annatto pigment, citrus Yellow, lutein, riboflavin or gardenia blue;

[0048] b) emulsifying and drying the mixed solution obtained in step a) to obtain a natural pigment composition.

[0049] Among the natural pigments selected by the present invention, gardenia yellow pigment, safflower yellow pigment and gardenia blue pigment are water-soluble pigments, capsanthin, lutein, citrus yellow pigment and riboflavin are oil-soluble pigments, curcumin, There are both water-soluble and oil-soluble products for annatto and monascus red pigments. Therefore, it is not possible to simply mix and apply various natural pigments.

[0050] In the invention, the selected pigments are firstl...

Embodiment 1

[0066] 200g of commercially available gardenia yellow (color value 100), 350g of commercially available safflower yellow (color value 150) and 500g of maltodextrin are completely dissolved in distilled water to obtain an aqueous solution; After emulsifying at a speed of 4500r / min for 10min, add 1000g of colloid, and emulsify at 48°C for 45min at a speed of 4500r / min, then cool down to 30°C to obtain a mixed solution; spray dry the mixed solution to obtain a solid The drying conditions of the product are as follows: the air inlet temperature is 185°C; the air outlet temperature is 85°C; the rotation speed of the electric nozzle is 2800r / min; the solid product is crushed into a 60-mesh natural yellow pigment composition for later use.

Abstract

The invention provides a natural pigment composition. The natural pigment comprises an emulsifier and two or more than two pigments of gardenia yellow pigment, curcumin, carithamine, citroxanthin, xanthophyll, riboflavin, capsaicin, monascus red pigment, bixa orettana pigment and gardenia blue. Natural pigments can prepare natural pigment compositions in different color systems and different tones in arbitrary proportions, such as yellow, orange, red, green and purple. Meanwhile, the natural pigment composition contains the emulsifier, so that the composition can be more uniform and more stable. Therefore, in the natural pigment composition provided by the invention, combinations of different natural pigments can overcome the defect of single pigment, for example, the light resistance of natural yellow pigment combined by the riboflavin, the curcumin and the like with poor light resistance and the gardenia yellow pigment with more stable light resistance is better than that of the riboflavin or the curcumin, thus the dosage can be reduced, and the cost can be 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 disadvantages, such as low solubility, not easy to color evenly; 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 hues. However, because different natural pigments have different physical and chemical properties, it is difficult to achieve arbi...
