Abstract

The invention discloses a method for raising the proportion of capsaicin monomer in capsicum oleoresin. The method comprises the steps of dissolving the capsicum oleoresin obtained through organic solvent extraction and decompressed concentration with an alcoholic solution, injecting the capsicum oleoresin into a chromatographic column filled with macroporous adsorption resin, leaving the capsicum oleoresin standing still for being adsorbed for 2-4 hours, then using an alcoholic solution for elution, conducting decompressed concentration on an elution solution, and obtaining capsicum oleoresin free of peculiar smell, wherein the total capsaicin content is 90-91%, and the proportion of the capsaicin monomers reaches 80-85%; continuing with elution with the alcoholic solution till eluant contains no capsaicin, conducting decompressed concentration on the eluant, and obtaining capsicum oleoresin free of peculiar smell, wherein the total capsaicin content is 93-94%, and the proportion of dihydrocapsaicin monomer reaches 45-50%. The method is obvious in effect, simple in process and easy and convenient to operate for separating capsaicin and dihydrocapsaicin, the solvent and resin can be recycled, no emission of industrial wastewater, waste gases and residues is generated, and the method is suitable for large-scale industrialized production.

Description

technical field [0001] The invention relates to the field of separation and extraction, in particular to a method for increasing the ratio of capsaicin monomer in capsicum oleoresin. Background technique [0002] The capsaicin substances in capsicum oleoresin are mainly capsaicin, dihydrocapsaicin and nordihydrocapsaicin, and the proportion of capsaicin monomer in natural capsaicin is generally 55-62%, and dihydrocapsaicin mono The proportion of natural capsaicin in the body is generally 25-30%. In order to increase the proportion of capsaicin monomer in capsicum oleoresin, unscrupulous businessmen add synthetic capsaicin to capsicum oleoresin to increase the proportion of capsaicin monomer in capsicum oleoresin, thereby disrupting the market and increasing their own Competitiveness. Combined with related reports, high performance liquid chromatography, reversed-phase silica gel column chromatography, solvent method and macroporous adsorption resin column chromatography ar...
