preparation example Construction

[0028] The preparation method comprises the following steps:

[0029] A. Add ester solvent in capsanthin slag, heat, stir, obtain capsanthin slag dissolving solution;

[0030] Capsanthin slag is any of the scum-like pigments produced during the production of capsanthin, the precipitated residue formed during the storage of capsanthin, or the centrifuged slag produced after centrifugation of capsanthin;

[0031] The ester solvent is any one of ethyl acetate, butyl acetate or isopropyl acetate, the ratio of the mass of capsicum red pigment slag in grams to the volume of the ester solvent in milliliters is 1:3-6, and the heating temperature is 40-40 60°C;

[0032] B. The solution of capsanthin slag is frozen at -15~-5℃ for 8~12h, then centrifuged at -15~-5℃ to obtain the filter residue and supernatant of capsanthin slag until the capsanthin slag The supernatant is clear and transparent, and there is no floc and precipitation when placed at -15~-5℃ for 30~60 minutes;

Embodiment 1

[0038] A method for refining capsanthin slag, comprising freezing and weak alkaline water treatment.

[0039] The preparation method comprises the following steps:

[0040] A. Add 300mL of ethyl acetate to 100g of dross-like pigment produced during the production of capsanthin with a color value of E120, heat to 60°C, stir evenly, and obtain a solution of capsanthin dregs;

[0041] B. Pass chilled water through the capsicum red pigment slag solution, cool down to -5°C, and freeze at -5°C for 8 hours. Centrifuge at -15°C to obtain filter residue and capsanthin residue supernatant. The capsanthin slag supernatant was placed at -5°C for 30 minutes without floc and precipitation;

[0042] C. Add 90mL of a mixed solution of sodium hydroxide solution and sodium carbonate solution to 270mL capsanthin slag supernatant, wherein the mass fraction of sodium hydroxide solution is 0.1%, and the mass fraction of sodium carbonate solution is 3%. The volume ratio of the solution and the so...

Embodiment 2～3

[0046] Embodiments 2-3 have the same production process steps as Embodiment 1, the difference is the selection of process parameters, as shown in Table 1 below.

Abstract

The invention discloses a capsanthin residue refining method and belongs to the field of plant extraction. The capsanthin residue refining method comprises freezing and weak alkaline solution treatment. The capsanthin residue refining method can reduce the content of phospholipid, wax, pectin and polysaccharides in capsanthin residues; refined capsanthin residues have the advantages of being goodin mobility and free from solidification at low temperature; the capsanthin residue refining method is simple and applicable large-scale industrialized production.

Description

technical field [0001] The invention relates to a method for refining plant extracts, in particular to a method for refining capsanthin residue, which belongs to the field of plant extraction. Background technique [0002] The main extraction method of capsanthin is organic solvent method. However, the selectivity of solvent extraction is poor, and it is often extracted together with phospholipids, pectin, polysaccharides, waxes and other components, and there is no alkali refining and deacidification process in the production of capsanthin. , resulting in poor pigment stability, precipitation, delamination, wall hanging, and even coagulation and agglomeration will occur after long-term storage. To solve this problem, most manufacturers adopt the method of pumping the upper layer or centrifuging after sedimentation. The quality of the supernatant is better, but the separated capsanthin slag has many impurities, viscous, agglomerated, high freezing point, and hala smell, res...
