Problems solved by technology

Due to the extremely low content of capsaicin in capsicum and a large number of complex components, the extraction and separation process is complicated, the yield is extremely low, and only crude products can be obtained
Therefore, many researchers just adopt methods such as paper chromatography, thin-layer chromatography, liquid chromatography to separate and purify capsaicin, obtain relatively pure capsaicin product, and these methods also mostly all can't realize suitability for industrialized production

Embodiment Construction

[0027] The present invention is described in further detail below by specific embodiment:

[0028] The preparation method of capsaicin in the present embodiment comprises three steps of extracting middle pepper essence, extracting capsaicin mixture and preparing high-purity capsaicin:

[0029] (1) Extracting medium-spicy capsicum essence:

[0030] 1. Put 30kg of low-spicy capsicum essence with a spiciness of 1.8% into a stainless steel extraction reaction kettle, add 120kg of ethyl acetate, stir for 0.5 hours, pressurize into a stainless steel separation and precipitation tank for precipitation and separation; after 6 hours of precipitation and separation , put the precipitate back into the extraction reaction kettle, and pour the supernatant into the receiving tank to be evaporated.

[0031] 2. The precipitate in the extraction kettle is subjected to secondary extraction and precipitation separation; a total of three times.

[0032] 3. Combine the three extracts, pump them ...

Abstract

The invention discloses a preparation method of capsaicin. The preparation method comprises following three steps: extraction of middle pungency degree chilli extract, extraction of a capsaicin mixture, and preparation of high purity capsaicin. The capsaicinoids content of an obtained product is larger than 95%; the total yield is higher than 60%; production technology is simple; complete separation is realized; capsaicin yield is high; by-products obtained via each step can be taken as chilli extracts for application after treatment; no waste is generated; solvents adopted in the preparation method are common solvents, and are convenient to recycle, and no environment pollution is caused; a selected chromatography media can be recycled after regeneration, and production cost is low; chilli extract is taken as a raw material, so that added value of chilli extract is increased, and chilli processing industry chain is prolonged.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of biological extraction, and relates to a process for extracting capsaicin from capsicum, in particular to a preparation method for capsaicin. [0003] technical background: [0004] Capsicum is a perennial herb of the Solanaceae Capsicum genus, and it is a spicy seasoning commonly used in human daily life. Its functions are "dispelling food, relieving stagnant qi, appetizing, warding off evil, and killing all poisons." ("Food Materia Medica"); "Mirror"); "Warming the middle and dispelling cold, eliminating wind and sweating, removing cold addiction, relieving phlegm and expelling dampness." ("Pharmaceutical Release"); Tinea" ("Drug Test"), in addition, there are discussions about the use of pepper as medicine in "Compendium Supplements" and "Yi Zong Compilation". According to the viewpoint of modern medicine, capsicum mainly utilizes the function of its spicy component as medicine. The effect on ...
