Embodiment 1

[0065] (1) Clean and shred

[0066] Put 1.5 tons of fresh beet red into the drum cleaning machine lined with brush at 3 tons / hour, adjust the rotation speed of the drum couple, wash with 6 tons / hour of running water, remove sediment and impurities, and use mechanical cutting into filaments.

[0067] (2) Extract and filter

[0068] Put the filaments in a multi-functional extraction tank, soak and extract for 6 hours according to the citric acid aqueous solution of filament: solution = 1:9, the pH of the acidic aqueous solution is 2.5-5, and collect the beet red pigment at the outlet of the multi-functional extraction tank aqueous solution. Filter the collected red pigment solution with a diatomaceous earth filter to obtain a clear beet red pigment solution.

Abstract

The invention relates to a preparation method of a multi-tone beet red pigment, and the preparation method is characterized in that fresh red beet is adopted as a raw materials to be continuously produced through the procedures of washing, slicing, extraction, filtering, column chromatography, color protection, concentration, color matching, ultrafiltration, microcapsulization, atomizing drying and mixed treatment, a beet red pigment product is obtained by utilizing a method combining a staging elution process of macroporous resin with a particular model number, pure water with particular electric conductivity and the mixed antioxidant, the color value of the beet red pigment product is more than or equal to 80, color tones include orange red (b: 14 to 8), pink (b: 8 to 5), true red (b: 5 to 0) and amaranth (b: 0 to 10). The beet red pigment has characteristics of light resistance, heat resistance, stability and the like. The beet red pigment is better than similar product standard both at home and abroad.

Description

technical field [0001] The invention relates to a method for extracting beet red pigments from natural beets, in particular to a preparation method for beta red pigments with various hues. Background technique [0002] Natural pigments are safe, non-toxic, and naturally colorful, and are deeply loved by people. Now they have been widely used in the coloring of food, medicine, health care products, and fine chemical products, etc., and can bring huge economic benefits to my country's export earnings. Therefore, governments and entrepreneurs of various countries are very concerned. The natural beet red pigment extracted from beet red has the advantages of low cost, stable and reliable quality. At present, the patent number of the beet red pigment preparation patent published in China has 97100782.9 and so on. However, the existing preparation method can only produce beet red pigment with one color tone, and at the same time, it has the disadvantages of low color price, weak h...
