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

[0070] 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 present invention provides a natural pigment composition, which comprises an emulsifier and two or more than two pigments selected from gardenia yellow pigment, curcuminoid, saffower yellower, orange yellow pigment, lutein, riboflavin, capsanthin, monascus red pigment, annatto and gardenia blue pigment. According to the present invention, various natural pigkments are blended according to any ratios so as to obtain the natural pigment compositions having different color systems and different tones such as yellow, orange, red, green and purple, and the natural pigment composition contains the emulsifier so as to make the composition uniform and stable, such that in the natural pigment composition, the combination of different natural pigments can make up the defects of the single pigment, wherein the light resistance of the natural yellow pigment obtained by combining the poor light resistance riboflavin, the poor light resistance curcuminoid and the like and the stable gardenia yellow pigment is superior to the light resistance of the riboflavin or curcuminoid so as to reduce the use amount and reduce the cost.

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...
