[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.
[0071] Adopt spectrophotometer to measure the absorbance value A0 of natural yellow pigment composition and the absorbance value A of the natural yellow pigment composition after 6 months of storage at room temperature in the dark, and its pigment...
Embodiment 2
[0075] 50g commercially available curcumin (color value 1500) and 120g commercially available capsanthin (color value 220) are emulsified and dissolved with 500g commercially available molecular distillation monoglyceride and 200g sucrose ester to obtain an emulsion; 300g commercially available The monascus red pigment (color value 100) was dissolved in distilled water and added to the emulsion, emulsified while adding, then added 600g of colloid and 1000g of maltodextrin, and emulsified at 40°C for 50min at a speed of 4500r / min. Cool down to 20°C under vacuum conditions to low
[0076] Warm freeze-drying to obtain a solid product; then crush the solid product to 60 mesh to obtain a natural orange-red pigment composition;
[0077]Adopt spectrophotometer to measure the absorbance value A0 of natural orange-red pigment composition and the absorbance value A of the composite natural orange-red pigment after 6 months in the dark, at room temperature, and its pigment retention rate...
