Description

technical field

[0001] The invention relates to a method for extracting alliin organic substances from plants, and is a production process for extracting alliin from fresh garlic. Background technique

[0002] Garlic, also known as garlic, is the underground bulb of Allium sativum L. in the Liliaceae family. It is a medicinal and edible plant with a long history. Alliin, also known as alliin, is mainly present in the cells of garlic scale buds, and is colorless and odorless. Chemical name: S-allyl-L-cysteinesulfoxide (S-allyl-L-cysteinesulfoxide), C 6 h 11 o 3 SN, molecular weight: 177.22, melting point: 163.5ยฐC (decomposition), chemical formula:

[0003] It is easily soluble in water and insoluble in non-polar organic solvents such as ether. Alliin is unstable in nature. Under the action of allinase and water at room temperature, it is rapidly converted into allicin to produce acetone and ammonia. Allicin will be further decomposed into a v...
