Embodiment 1

[0025] 1) After taking out the commercially available chili peels with a storage temperature of -10°C, put them into a mill and pulverize them into 200-mesh chili powder.

[0026] 2) Weigh 100 parts by weight of chili powder into a Soxhlet extractor, add 400 parts by weight of tetrahydrofuran, perform Soxhlet extraction at 75°C for 20 minutes, 80°C for 20 minutes, and filter under reduced pressure. The filtrate was further concentrated into a concentrated solution by vacuum distillation, and dried to constant weight to obtain capsanthin crude material.

[0027] 3) Add 10 parts by weight of crude capsanthin into 30 parts by weight of n-bromopropane solvent, extract with a vortex mixer for 3 minutes, and centrifuge for 2 minutes in a high-speed centrifuge to obtain pure capsanthin.

Embodiment 2

[0029] 1) After taking out the commercially available chili peels with a storage temperature of -10°C, put them into a mill and pulverize them into 300-mesh chili powder.

[0030] 2) Weigh 100 parts by weight of chili powder into a Soxhlet extractor, add 600 parts by weight of tetrahydrofuran, perform Soxhlet extraction at 75° C. for 30 minutes, 80° C. for 30 minutes, and filter under reduced pressure. The filtrate was further concentrated into a concentrated solution by vacuum distillation, and dried to constant weight to obtain capsanthin crude material.

[0031] 3) Add 10 parts by weight of crude capsanthin into 50 parts by weight of n-bromopropane solvent, extract with a vortex mixer for 5 minutes, and centrifuge for 2 minutes in a high-speed centrifuge to obtain pure capsanthin.

Embodiment 3

[0033] 1) After taking out the commercially available chili peels with a storage temperature of -10°C, put them into a mill and pulverize them into 280-mesh chili powder.

[0034] 2) Weigh 100 parts by weight of chili powder into a Soxhlet extractor, add 500 parts by weight of tetrahydrofuran, perform Soxhlet extraction at 75° C. for 25 minutes, 80° C. for 30 minutes, and filter under reduced pressure. The filtrate was further concentrated into a concentrated solution by vacuum distillation, and dried to constant weight to obtain capsanthin crude material.

[0035] 3) Add 10 parts by weight of crude capsanthin into 40 parts by weight of n-bromopropane solvent, extract with a vortex mixer for 4 minutes, and centrifuge for 2 minutes in a high-speed centrifuge to obtain pure capsanthin.

Abstract

The invention discloses an extraction method of capsicum red pigment. The method comprises following steps: commercially available capsicum skin stored at -10 DEG C is prepared, and is introduced intoa powder milling machine for crushing to obtain 200 to 300 mesh capsicum powder; 100 weight parts of the capsicum powder is introduced into a Soxhlet extractor, 400 to 600 weight parts of tetrahydrofuran is added, Soxhlet extraction is carried out for 20 to 30min at 75 DEG C, and Soxhlet extraction is carried out for 20 to 30min at 80 DEG C, and reduced pressure filtering is carried out; an obtained filtrate is subjected to further condensation through reduced pressure distillation to obtain a concentrate, and the concentrate is dried until the weight is constant so as to obtain a capsicum red pigment crude material. The technology flow is simple, technology time period is short, capsicum red pigment extraction rate is high, quality is stable, the extraction rate is capable of reaching 97.15 to 98.97%, and is higher than that in the prior art.

Description

technical field [0001] The invention belongs to the technical field of natural food additive production, and in particular relates to a method for extracting capsanthin. Background technique [0002] Capsanthin, also known as capsanthin and capsicum oleoresin, is a natural colorant extracted from peppers. The main coloring components are capsanthin and capsanthin, which belong to carotenoids and account for 0.2%-0.5% of pepper peels. . [0003] Foreign scholars have conducted in-depth and detailed research on carotenoids in peppers. More than 50 carotenoids have been isolated from peppers, of which more than 30 carotenoids have been identified. Studies have shown that the main components of capsanthin are capsanthin and capsanthin. Generally speaking, capsanthin (color value 10,000 units) has the following average indicators: 80% to 85% fatty acids, mainly composed of linoleic acid, oleic acid, palmitic acid, stearic acid, and myristic acid; vitamin E0 .6%-1.0%; vitamin ...
