Embodiment 1

[0055] (1) Extract and filter

[0056] With 500 kg of safflower, the safflower is sent into the multi-functional extraction tank by the conveyor belt at 3 tons / hour, soaked and extracted by safflower:solution=1:22 citric acid aqueous solution for 6 hours, the pH of the acidic aqueous solution=3.5, in the multi-functional extraction tank The liquid outlet of the functional extraction tank collects the aqueous solution of safflower yellow pigment. Filter the collected red pigment solution with a diatomaceous earth filter to obtain a clear safflower yellow pigment solution.

[0057] (2) Column chromatography

[0058] Put the clarified safflower yellow pigment solution on the D101 macroporous resin adsorption column, the column height is 3m, the diameter is 0.8m, the resin is filled with 300kg, the feed flow rate is 6kg / min, and it is washed with pure water with a conductivity of 25us. Then, it was eluted and separated with ethanol aqueous solution, and then washed with deionize...

Embodiment 2

[0077] (1) Extract and filter

[0078] With 500kg of safflower, the safflower is sent into the multi-functional extraction tank by the conveyor belt at 3 tons / hour, soaked and extracted in the lactic acid aqueous solution of safflower:solution=1:15 for 4 hours, and the pH of the acidic aqueous solution is 2.5. The liquid outlet of the extraction tank collects the aqueous safflower yellow pigment solution. Filter the collected red pigment solution with a diatomaceous earth filter to obtain a clear safflower yellow pigment solution.

[0079] (2) Column chromatography

[0080] Put the clarified safflower yellow pigment solution on a DM-21 macroporous resin adsorption column, the column height is 3m, the diameter is 0.8m, the resin is filled with 300kg, the feed flow rate is 2kg / min, and it is washed with pure water with a conductivity of 20us. Then, it was eluted and separated with ethanol aqueous solution, and then washed with deionized water until neutral.

Embodiment 3

[0094] (1) Extract and filter

[0095] With 500 kg of safflower, the safflower is sent into the multi-functional extraction tank by the conveyor belt at 3 tons / hour, soaked and extracted in acetic acid aqueous solution of safflower:solution=1:30 for 8 hours, and the pH of the acidic aqueous solution is 5. The liquid outlet of the extraction tank collects the aqueous safflower yellow pigment solution. Filter the collected red pigment solution with a diatomaceous earth filter to obtain a clear safflower yellow pigment solution.

[0096] (2) Column chromatography

[0097] Put the clarified safflower yellow pigment solution on the NSA-9 macroporous resin adsorption column, the column height is 3m, the diameter is 0.8m, the resin is filled with 300kg, the feed flow rate is 10kg / min, and the pure water with a conductivity of 30us is used for cleaning. Then, it was eluted and separated with ethanol aqueous solution, and then washed with deionized water until neutral.

Abstract

The invention relates to a preparation method of high-quality arthamin yellow, and the preparation method is characterized in that fresh arthamin is adopted as a raw material, continuous production of washing, slicing, extraction, filtering, column chromatography, color protection, concentration, color matching, ultrafiltration, microcapsulization, atomizing drying and mixed treatment is undertaken for the fresh arthamin, a arthamin yellow product is obtained by utilizing a method combining a macroporous resin staging elution process of a particular model number, pure water with particular conductivity and mixed antioxidant, the color value of the arthamin yellow product is more than or equal to 260, and the prepared arthamin yellow has characteristics of light resistance, heat resistance, stability and the like. The arthamin yellow is better than similar products standard both at home and abroad.

Description

technical field [0001] The invention relates to a method for extracting safflower yellow from natural safflower, in particular to a method for preparing high-quality safflower yellow. Background technique [0002] Natural pigments are safe, non-toxic, and naturally bright in color. They are deeply loved by people, especially for the coloring of food, medicine, health care products, and fine chemical products, as well as the huge economic benefits brought by export. Governments and entrepreneurs in various countries are very concerned. The natural safflower yellow extracted from safflower has the characteristics of low cost, stable and reliable quality, etc. At present, the patent numbers of safflower yellow preparation published in my country include 02133563.X, 03157479.3 and so on. However, the pigment produced by the existing safflower yellow preparation technology has a low color value, and has the disadvantages of poor heat stability and light stability, complex prepar...
