Problems solved by technology

High-purity capsaicin has many physiological activities, such as analgesic, anti-inflammatory, appetite-stimulating, improving digestion, antibacterial and insecticidal, and neurotransmitter selectivity. However, some phenolic substances in crude capsaicin can antagonize capsaicin Active on neuropeptides, it aggravates pain and inflammation, so capsaicin must be purified to have application value

Abstract

The invention belongs to the field of natural organic chemistry, and relates to a method for purifying capsicine in hot pepper by using microwave countercurrent extraction-membrane filtration technologies in a combined way. The method is characterized in that: microwave countercurrent extraction and membrane filtration are performed in sequence, so that the extraction time is shortened, the extraction speed is increased, the extraction rate is increased by dozens of times, and the extraction period is shortened greatly. Meanwhile, the content of active ingredients is increased, medicinal materials and energy consumption are saved, and the defects of relatively low conventional extraction rate and low extraction purity are overcome. Furthermore, the content of active ingredients is increased, the extraction purity is high, and a final capsicine product of which the content is over 98 percent can be obtained. Due to the adoption of the method for using microwave countercurrent extraction-membrane filtration technologies in a combined way, an organic solvent is extracted completely, the membrane filtration technology is safe and reliable, the microwave technology has a high extraction speed, pollution is avoided, environment-friendly engineering is adopted, a production line has a simple constitution, a processing process is simple and contributes to saving medicinal materials and lowering energy consumption, and the defects of relatively low conventional extraction rate and low extraction purity are overcome.

Description

technical field [0001] The invention belongs to the field of natural organic chemistry and relates to a method for purifying capsaicin in capsicum. Background technique [0002] Capsicum is the fruit of Solanaceae capsicum. It is native to South America, Mexico and other tropical areas of Central America and the West Indies. It was introduced to my country around the end of the Ming Dynasty. Capsicum has become an important spicy food for people now. It is widely cultivated in Gansu, Shaanxi, Hunan, Sichuan, Guizhou, Yunnan and other provinces and regions in my country, and its resources are abundant. Pepper is a vegetable with the same source of medicine and food, which contains alkaloids, pigments, vitamins, organic acids, minerals and other ingredients. Capsaicin is an alkaloid with N-vanillylamide structure in capsicum fruit. The chemical composition of capsaicin is mainly capsaicin and dihydrocapsaicin, both of which account for about 90% of the entire capsaicin, and ...
