Embodiment Construction

[0015] The steps of the allicin extraction method include peeling and washing garlic → homogenizing → reacting → extracting with an organic solvent → shaking first, then standing for stratification → supernatant liquid → concentrating under reduced pressure → concentrating the allicin solution.

[0016] The specific operation is as follows:

[0017] (1) Peel the garlic bulbs, weigh 100g each, 10 groups in total, 3 parallel parts for each group, the first group does not add pyridoxal phosphate and reduced glutathione in the homogenization step; the 2nd, 3rd, Group 4 added reduced glutathione in the homogenization step, and the amount added was 0.4%, 0.6%, and 0.8% by weight of garlic respectively; Groups 5, 6, and 7 added pyridoxal phosphate in the homogenization step, adding 0.4‰, 0.6‰, and 0.8‰ according to the weight of garlic, respectively; Groups 8, 9, and 10 added reduced glutathione and pyridoxal phosphate in the homogenization step, and the amount of reduced glutathione...

Abstract

The invention relates to a pretreatment method for extracting allicin. The pretreatment method for an extraction method for allicin comprises the following steps: garlic peeling and cleaning, and homogenizing, wherein pyridoxal phosphate and/or glutathione is added in garlic slurry in the homogenizing step. According to the pretreatment method disclosed by the invention, the yield of extraction for allicin is remarkably increased.

Description

technical field [0001] The invention belongs to the technical field of chemical production, and in particular relates to a pretreatment method for extracting allicin and an extraction method for allicin. Background technique [0002] my country is an important producer and exporter of garlic in the world, and allicin is a biologically active organic sulfide produced by alliin under the catalysis of alliinase after garlic bulbs are broken, scientific name diallyl Thiosulfinate. Allicin has a wide range of physiological effects, such as antibacterial and anti-inflammatory, lowering blood fat, lowering cholesterol, enhancing blood vessel elasticity and lowering blood pressure, regulating blood sugar, preventing cancer, enhancing immune function, detoxification and health care. Therefore, there are many studies on the extraction methods of allicin. At present, the extraction methods of allicin are basically divided into three categories: steam distillation, organic solvent extr...
