Embodiment

[0026] Embodiment, carry out according to the following steps:

[0027] The first step is pretreatment: microwave the garlic cloves to kill enzymes until the garlic cloves turn from white to translucent; it is best to put the garlic cloves in the microwave for 2 minutes, 3.5 minutes or 5 minutes, and the microwave frequency is preferably 2540 ±50MHz, the output microwave power is preferably 20KW. Before microwave enzyme treatment, it is best to remove the garlic cloves and wash and drain.

[0028] The second step is to extract organic matter: Grind the garlic cloves after microwave treatment into 100 to 200 mesh garlic pulp, add ethanol or alcohol, use an ethanol hydrometer to control the ethanol concentration of the garlic pulp to 40% to 70%, and stir for 2 to 10 hours , separated to obtain the extract, and concentrated the extract under reduced pressure. It is best to re-extract 3 or 5 times by weight. It is best to use the multi-effect decompression film concentration me...

Abstract

The extraction process of alliin from fresh garlic includes the steps of: pre-treatment to kill enzyme of garlic with microwave; organic extraction through ginding garlic into slurry, ethanol extraction, separating extractive liquid and depression concentration; cationic exchange resin adsorption of alliin from concentrated extractive liquid; ammonia water desorption of alliin; and obtaining alliin crystal. The said process has alliin yield of 0.1% and product has alliin content of 91.2%.

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: 163.5°C (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...
