Embodiment 1

[0051] With 200g commercially available gardenia yellow pigment (color price 6320), 50 commercially available curcumin (color price 100), 250g commercially available purple sweet potato red pigment (color price 450), 500g carrageenan are completely mixed with distilled water. Dissolve, add 4g of soybean protein isolate, 5g of citric acid-diammonium hydrogen phosphate pH adjuster to obtain a solution; put the solution into an emulsifier, emulsify at room temperature at a speed of 4500r / min for 10min, and at 48°C Insulate and emulsify at a speed of 4500r / min for 45 minutes, then cool down to 30°C to obtain a mixed solution; spray dry the mixed solution to obtain a solid product, and the drying conditions are: the inlet air temperature is 185°C; the outlet air temperature is 85°C ; The rotation speed of the electric nozzle is 2800r / min; The solid product is crushed to 60 mesh natural yellow pigment composition for later use.

Abstract

The invention provides a natural pigment composition. The natural pigment composition is prepared from emulgator, at least two of gardenia yellow pigment, curcumine, norbixin, carthamin yellow, citrus yellow pigment, xanthophyll and riboflavin, and at least one of purple sweet potato red pigment, mulberry red pigment, chestnut shell pigment and blueberry pigment. The uniform and stable natural pigment composition which is of different color systems and different hues can be obtained by mixing the natural pigment according to any ratio, and the defects of single pigment are overcome. Meanwhile, the pigment composition can be more stable due to the red pigment, a chelating agent and a pH regulating agent which are contained by the pigment composition. The invention further discloses a preparation method of the natural pigment composition. The method is simple and easy to operate.

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 ar...
