Abstract

The invention belongs to the technical field of deep processing of garlic and particularly relates to a process method and a preparation method for synthesizing ajoene from allicin. The process method comprises the steps of extracting allinase, purifying allinase, immobilizing allinase, preparing allicin, synthesizing ajoene, and purifying ajoene. According to the process method, allinase is immobilized by virtue of an enzyme immobilization method and is converted into allicin through catalysis in a bioreactor, the reaction specificity is good, the catalytic efficiency is high, and a high-purity allicin product can be obtained; by aiming at characteristics of cleavage reaction of allicin, allicin is complexed by virtue of a hydrophilous complex in a complex catalysis reaction manner, so that the stability of allicin is improved; allicin is decomplexed in a reaction process and can timely react so as to generate ajoene, so that a large number of side reactions are avoided.

Description

technical field [0001] The invention belongs to the technical field of garlic deep processing, and in particular relates to a process method for synthesizing ajoene from allicin and a preparation method thereof. Background technique [0002] Allicin (allicin, garlicin) is a trithioallyl ether compound that naturally exists in the bulbs of the liliaceous plant garlic. It has antibacterial effect on a variety of Gram-positive and negative bacteria, and has antibacterial effects on bacilli (shigella, typhoid bacillus, Escherichia coli, pertussis bacillus), fungi (candida albicans, cryptococcus, aspergillus fumigatus), viruses (cytomegalovirus ), amoeba, trichomonas vaginalis, pinworm, etc. all have inhibitory and killing effects, especially for intestinal bacteria such as Escherichia coli and Shigella. [0003] However, allicin is extremely unstable and will decompose at room temperature. As an active ingredient derived from garlic, ajoene is more stable than allicin and does...
