Problems solved by technology

To obtain these two substances from red peppers, the organic solvent extraction method is generally used at present, including two processes: one, only the pigment is extracted, or only capsaicin is extracted, and another component is not considered to be recovered at the same time. Unreasonable economically, it is impossible to be applied in industry; two, extract and separate pigment and capsaicin simultaneously, disclose a kind of " new technology of extracting capsanthin and capsaicin from red pepper as Chinese invention patent (CN1083083A) ", take paprika powder as raw material, extract with petroleum ether to obtain the extract containing capsanthin and capsaicin (being capsaicin), carry out salting-extraction treatment to extract with saline solution and industrial acetone, leave standstill layering Obtain capsanthin-containing liquid layer and capsaicin liquid layer respectively, then obtain capsanthin and capsaicin respectively by decompression distillation and remove solvent
Although this process is economically reasonable, the resulting product has high solvent residues, a strange smell, and low quality, which is difficult to meet the requirements of domestic and foreign users.

Embodiment 1

[0014] Weigh 100 g of 60-mesh dry chili powder, add 95% ethanol for extraction by weight, feed the material according to the solid-to-liquid weight ratio of raw material powder and ethanol as 1:3, and extract under reflux at 50 ° C for 1 hour, after that, collect the filtrate by filtration and filter residue, and then use the filter residue as raw material powder, add ethanol and feed again according to the solid-liquid weight ratio of raw material powder and ethanol as 1:3, repeat the above extraction process, obtain the filtrate and filter residue for the second time, and combine the two filtrates in Together, ethanol is recovered by distillation under reduced pressure to obtain a crude oily product rich in capsaicin and capsaicin.

[0015] Put the crude product of the above-mentioned oil into the extraction kettle in the supercritical device, and before the extraction, CO 2 First liquefied by refrigeration, and then pumped into the extraction kettle through a high-pressure ...

Embodiment 2

[0017] Weigh 100 g of 150-mesh dry chili powder, add 95% ethanol for extraction by weight, feed the material according to the solid-to-liquid weight ratio of raw material powder and ethanol as 1:3, and extract under reflux for 1 hour at 70 ° C, after that, collect the filtrate by filtration and filter residue, use filter residue as raw material powder, add ethanol and repeat the above-mentioned extraction process, obtain the filtrate and filter residue for the second time, repeat the above-mentioned extraction process in this way for a total of 5 times, then combine the filtrates obtained for 5 times together, by reducing Ethanol is recovered by pressure distillation to obtain a crude oily product rich in capsaicin and capsaicin.

Abstract

The process of separating capsorubin and capsaicine from hot pepper includes first extraction of capsorubin and capsaicine from hot pepper material with high concentration alcohol, decompression distillation and concentration to obtain oily coarse capsorubin and capsaicine product, and supercritical fluid extraction to separate capsorubin and capsaicine with different dissolubility in CO2. The process can obtain capsorubin and capsaicine with high purity, no residual solvent and no bad smell simultaneously. The process is simple, economic, easy in operation and suitable for industrial production. Capsorubin is used in food pigment, cosmetics and health food, and capsaicine is used in medicine.

Description

technical field [0001] The invention relates to a method for separating capsaicin and capsaicin from capsicum, solvent extraction and supercritical CO 2 The extraction technology is combined, and two products of capsanthin and capsaicin are extracted and refined simultaneously, which belongs to the field of separation of natural products in the chemical engineering discipline. Background technique [0002] Capsanthin and capsaicin are two eye-catching components in peppers. The former is an excellent natural edible red pigment, which has been widely used in food, advanced feed and other fields; It has a significant effect on postherpetic neuralgia, trigeminal neuralgia, diabetic neuralgia, rheumatoid arthritis, osteoarthritis, psoriasis, and alopecia. To obtain these two substances from red peppers, the organic solvent extraction method is generally used at present, including two processes: one, only the pigment is extracted, or only capsaicin is extracted, and another comp...
