Embodiment Construction

[0014] A supercritical CO 2 The method for extracting capsanthin comprises the following steps:

[0015] (1) Pepper treatment: remove the seeds, stalks, and sort out the impurities in the peppers, clean them, and dry them until the water content is not more than 10%. Grind the above-mentioned processed peppers with a grinder and pass through 200 mesh Sieve to get chili powder;

[0016] (2) Alcohol extraction, adding 75% ethanol equal to 5 times the weight of chili powder to the chili powder for extraction, and then separating the extracted slag to obtain the extract;

[0017] (3) Separating the extract by membrane, recovering the solvent, and removing by-products;

[0018] (4), supercritical CO 2 Extraction, the extraction pressure is 22.5MPa, the extraction temperature is 46.5°C, the separation temperature is 60°C, the separation pressure is 4 Mpa, the solid-liquid ratio of the entrainer is 1:3, and the extraction time is 3h. Under the combination of pressure and temperatu...

Abstract

A related method for extracting capsicum haematochrome from capsicum comprises the following steps: (1) processing capsicum; (2) performing alcohol extraction, namely, adding 80% ethanol with the usage amount being 5-8 times by weight of capsicum powder into capsicum powder for extraction, then performing solid-liquid separation to separate out material slag, and purifying the extraction liquid; (3) performing membrane separation; (4) performing supercritical CO2 extraction, and controlling the extraction pressure to be 20 MPa, the extraction temperature to be 40 DEG C, the separation temperature to be 50 DEG C, the extraction time to be 3 h, the entrainer material-liquid ratio to be 1:2 and the extraction time to be 3 h; and (5) performing examination, metering and packaging on the separated out capsicum haematochrome. The provided capsicum haematochrome extraction method is simple, does not employs toxic solvents and is high in capsicum haematochrome extraction rate, and the extracted capsicum haematochrome is high in purity and has the purity up to 95% or more.

Description

technical field [0001] The invention belongs to the field of plant extraction, and in particular relates to a method for extracting capsanthin from capsicum. Background technique [0002] Capsanthin, also known as capsanthin, is a tetraterpenoid orange-red pigment present in ripe red pepper fruits, belonging to carotenoid pigments. Capsicum red pigment has bright color, high color value, strong tinting strength and good color retention effect. It is not only widely used in the coloring of various foods such as aquatic products, meat, cakes, salads, cans, beverages, etc., but also can effectively prolong the life of simulated food. long shelf life and high safety. Capsanthin has the function of nutrition and health care, and it has been proved by modern science that it has anti-cancer, anti-radiation and other functions and has a good development prospect. But now the extraction method of capsanthin is complicated and the extraction rate is low. Contents of the invention ...
