Problems solved by technology

[0004] The existing capsanthin detoxification process mostly uses intermittent detoxification equipment such as deodorizing pots, and the detoxification time is more than one hour, which has the disadvantages of long detoxification time and low detoxification efficiency, which easily causes the loss of color value of capsicum red pigment High, not conducive to industrial continuous production

Embodiment 1

[0029] 1) Using capsanthin crude product with 5% solvent content after removing capsaicin as raw material, add 0.3% tocopherol (directly added, no need to dissolve in solvent).

[0030] 2) The crude product of capsanthin containing antioxidant is subjected to secondary series series removal, and the removal equipment is a short-range evaporator. The first-level and second-level removal equipment are all heated by hot water. The temperature of the hot water is 65°C and 68°C. The pressures of the first-level and second-level removal equipment are -0.090MPa and -0.0999Mpa respectively. Nitrogen gas with a purity of 99.99% (volume fraction) is introduced, and the nitrogen flow rate is 10m 3 / h.

[0031] The deresidue time of capsanthin in this process is 30 minutes (the time of passing through the two-stage series short-range evaporator).

[0032] 3) Enter the condenser after the second stage of residue removal, and the temperature of the finished capsanthin pigment drops to 20°...

Embodiment 2

[0034] 1) Using capsanthin crude product with capsaicinoid removed and solvent content of 1% as raw material, add 0.8% mixture of tocopherol and tea polyphenol antioxidant (mass ratio 1:1). Add directly, no need to dissolve in solvent.

[0035] 2) The crude product of capsanthin containing antioxidant is subjected to secondary series series removal, and the removal equipment is a short-range evaporator. The primary and secondary removal equipment are all heated by hot water, the temperature of hot water is 62°C and 70°C in turn, the pressure of the primary and secondary removal equipment is -0.100MPa, -0.100Mpa respectively, and the secondary short-path evaporator Introduce carbon dioxide gas with a purity of 99.95%, and the gas flow rate is 1m 3 / h.

[0036] 3) Enter the condenser after the second stage of residue removal, and the temperature of the finished capsanthin pigment drops to 23°C. The color value yield of capsanthin is 99.9%, and the total organic solvent residu...

Abstract

The invention provides a method for producing low soluble residue capsanthin. The method comprises the following steps: 1) taking crude capsanthin in which capsicin is completely removed as a raw material, and adding an antioxidant accounting for 0.3-0.8% of the mass of the raw material; 2) performing continuous secondary tandem residue removal on the crude capsanthin containing the antioxidant, and introducing inert gases in the second-level residue removal process; 3) enabling the capsanthin to enter a condenser for cooling after residue removal is completed, and reducing the temperature to be 25 DEG C or lower. According to the method provided by the invention, the soluble residues are removed from the capsanthin by using a continuous two-level short-range evaporator, the inert gases are introduced into the two-level flavor removal process, the treatment time is short, and the chroma loss is low. The antioxidant is added in the capsanthin residue removal process, the capsanthin is cooled by the condenser after residue removal, the chroma loss is further reduced, and the pigment loss of the capsanthin at the storage phase is avoided.

Description

technical field [0001] The invention belongs to the field of extraction of plant raw materials, and in particular relates to an extraction method using antioxidants. Background technique [0002] Capsanthin is a natural tetraterpenoid pigment extracted from ripe red pepper fruit, which has bright color, strong tinting power, high safety, nutrition and health care, etc. The methods for producing capsanthin include organic solvent method, supercritical extraction method and oil-soluble method. Among them, the organic solvent method is the most widely used. It uses mature red peppers as raw materials, and uses solvents such as 6# solvent oil, acetone or ethanol to extract a mixture containing capsanthin and capsaicin. The mixture after concentrating the solvent is called red hot pepper. The red capsicum is processed by ethanol and other solvents to obtain the finished capsanthin. [0003] At present, the equipment used to remove the residual solvent in capsanthin is mainly a ...
