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

[0026] The specific embodiment of the present invention is divided into three steps and is processed and prepared into high-purity capsaicin.

[0027] Step 1: Extract the low-spicy capsicum essence through solvent extraction to prepare the medium-spicy capsicum essence.

[0028] 1. Put 30kg of low-spicy capsicum extract 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.

[0029] 2. The precipitate in the extraction kettle is subjected to secondary extraction and precipitation separation; a total of three times.

[0030] 3. Combine the three extracts, pump them into the evaporator for vacuum evaporation and concentration, the evapo...

Abstract

The invention relates to a process for preparing capsaicin with high hotness or capsaicin from natural peppers, especially a method for preparing capsaicin with low hotness capsaicin as the basic raw material. The technical scheme of the invention includes extracting medium spicy Capsaicin essence, preparation of oily capsaicin mixture and preparation of high-purity capsaicin are three process steps. The content of capsaicin in the prepared product is greater than 95%; the total yield is greater than 60%. The production process is simple and the separation is thorough; the yield of capsaicin is high. , and the by-products obtained in each step can be processed and used as pepper essence without waste; the solvents used in the production process are common solvents, which are easy to recycle and reuse, and have no environmental pollution; the selected chromatography medium can be regenerated and used repeatedly , low production cost; using capsicum extract as a raw material not only increases its added value, but also prolongs the industrial chain of capsicum processing.

Description

Technical field: [0001] The invention relates to a process for preparing high-purity capsicum extract or capsaicin from natural peppers, in particular to a method for preparing capsaicin with low-spicy capsicum extract as a basic raw material. technical background: [0002] 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....
