Problems solved by technology

[0002] At present, most of the methods for extracting and separating capsaicin and capsanthin from red peppers use solvent extraction methods, such as ZL94104403.3 and CN1439630A, etc. Although industrialized production has been realized, these methods all use a single organic solvent to extract
If ethanol is used as the extraction agent for extraction, the extraction of capsaicin is relatively complete, but the extraction of capsanthin is not thorough, and No. 6 solvent oil is used as the extraction agent, and the extraction of capsanthin is relatively complete, on the contrary for capsaicin The extraction is not thorough, so the extraction rate of active ingredients is not ideal in general, and the key process of separation of capsaicin and capsanthin is required for the extract, so as to obtain more ideal capsaicin and capsanthin.

Embodiment 1

[0024] First add 1000 liters of 55% ethanol and 600 liters of No. 6 solvent oil in the extraction tank, after starting to stir, add 200 kg of dried chili powder (total color value 1900, capsicum total alkali 0.9 kg), filter after extracting at room temperature for 2 hours, repeat Leach 2 times, the resulting filtrate was left to stand in a separator for 1 hour, and the separated No. 6 solvent oil phase was concentrated under reduced pressure to recover No. 6 solvent oil. Nitrogen was passed through the concentrate and the solvent residue was removed under reduced pressure. , obtain high-quality capsanthin 9kg. The separated ethanol phase is concentrated under reduced pressure to reclaim the ethanol, and the concentrated water phase is cooled to 25° C., and after maintaining for 3 hours, 1.8 kg of capsicum essence product separated out is separated. After the aqueous phase of the mother liquor was adjusted to pH 7-8 with hydrochloric acid, it was transferred into the crystalliz...

Abstract

The invention provides a process for extracting and separating capsicine and capsicum red pigment from capsicum, which comprises using 50-75% of No.7 alcohol and No.6 solvent oil as mixed extraction agent, lixiviating the chilli powder and disintegrating the leach of the obtained mixed solvent, obtaining capsicum red pigment from No.6 solvent oil layer, obtaining capsicum extract from the ethanol solvent layer, and crystallizing in a crystallizer. The prepared capsicine crystalline body has a overall yield of capsicine to be 85-90%.

Description

technical field [0001] The invention relates to a method for extracting and separating capsaicin and capsanthin from red pepper. Using 50-75% ethanol and No. 6 solvent oil as a mixed extractant, extract capsaicin and capsanthin from dried red pepper powder. The method realizes synchronous extraction and separation, greatly shortens the production process, is easy to operate and control, and greatly improves the extraction rate of the product. technical background [0002] At present, most of the methods for extracting and separating capsaicin and capsanthin from red peppers use solvent extraction, such as ZL94104403.3 and CN1439630A, etc. Although industrialized production has been realized, these methods all use a single organic solvent as the extractant to extract.
