Problems solved by technology

At present, the method for preparing capsaicin is mainly divided into: one is the organic solvent extraction method, that is, the raw material is extracted, separated and recrystallized with different solvents, the process time is long, the organic solvent used is many, and the solvent consumption is large and has Toxic, flammable and explosive, have high requirements on industrial equipment, have an impact on the environment, and cause many difficulties to industrial production; the other is to combine supercritical carbon dioxide extraction (or molecular distillation method), that is, to extract raw materials with supercritical carbon dioxide ( Or take the molecular distillation method), need to use organic solvent to extract, and make capsaicin crystal after purification process again; The shortcoming of this type of method is that extractor volume is limited, and equipment i

Embodiment 1

[0008] The present invention comprises the following steps: A, take by weighing 50 kilograms of capsicum extract with a total content of capsaicin compounds of 27.60%, add it to 500 kilograms of 55% ethanol, stir and dissolve it fully, add 250 kilograms of hexane to the ethanol mixture, Stir well to dissolve, stand still for 2 hours and divide into two layers, the upper layer is the hexane extract, and the lower layer is the ethanol mixture for separation; B. Separate the hexane extract and place it separately, and then add the hexane 250 kilograms of alkane, after fully stirring and dissolving, separate after standing still for 2 hours, separate the hexane extract and merge with the first hexane extract to obtain about 510 kilograms of ethanol mixed solution simultaneously; C, combine the hexane Concentrate the alkane extract and deodorize in vacuum to obtain 39.53 kilograms of high-quality oil-soluble capsicum essence product, wherein the total content of capsaicin compounds ...

Embodiment 2

[0010] The present invention comprises the following steps: A, taking by weighing 50 kilograms of capsicum essence with a total content of capsaicin compounds of 27.38%, adding it to 500 kilograms of 60% ethanol, stirring and dissolving fully, adding 250 kilograms of sherwood oil to the ethanol mixture, Stir well to dissolve, stand still for 2 hours and divide into two layers, the upper layer is the petroleum ether extract, and the lower layer is the ethanol mixture for separation; B. Separate the petroleum ether extract and place it separately, and then add petroleum to the ethanol mixture 250 kilograms of ethers, after fully stirring and dissolving, separate after standing still for 2 hours, and merge with the petroleum ether extract for the first time after separating the upper strata sherwood oil extract, obtain about 510 kilograms of ethanol mixed solution simultaneously; C, after merging Petroleum ether extract concentration, vacuum deodorization, get 40.15 kilograms of h...

Abstract

The present invention relates to an industrial method for producing natural capsaicin, which includes the following procedures that: firstly extraction and separation, in which solvent A is used at first and mixed with the raw material under adequate agitation, then the mixture is extracted with solvent B as the extractant, the extract of solvent A is condensed, and the temperature of the liquid phase is lowered to obtain a thick jelly for later usage; secondly separation and crystallization, the thick jelly is dissolved with a heated lipid through adequate mixing, the mixture is cooled down and allowed for standing for crystallization, and the capsaicin crystal is obtained, thirdly rinsing and drying, the plant oil containing the capsaicin crystal is filtrated to obtain the crystal of capsaicin, which is rinsed with solvent B adequately to eliminate the plant oil, and the obtained crystal undergoes decompressed vaporization to eliminate the solvent to obtain the natural capsaicin crystal, in which the content of total alkali is more than percent. The present invention has much shortened technical process, decreased categories of organic solvent to be used, low fabrication cost and capability of environmental protection.

Description

technical field [0001] The invention relates to an industrialized method for producing natural capsaicin. Background technique [0002] The spicy ingredient in peppers is called capsaicin or capsaicin. Capsaicin crystals of different purity are widely used in military, food, medicine, agriculture and many other fields. At present, the method for preparing capsaicin is mainly divided into: one is the organic solvent extraction method, that is, the raw material is extracted, separated and recrystallized with different solvents, the process time is long, the organic solvent used is many, and the solvent consumption is large and has Toxic, flammable and explosive, have high requirements on industrial equipment, have an impact on the environment, and cause many difficulties to industrial production; the other is to combine supercritical carbon dioxide extraction (or molecular distillation method), that is, to extract raw materials with supercritical carbon dioxide ( Or take the ...
