Problems solved by technology

[0002] Soy isoflavone is a kind of bioflavonoid, which mainly refers to the compound with 3-benzopyrone as the core. The human body cannot synthesize it. It is distributed in nature and mainly exists in leguminous plants. Soy is the highest. Soy is the only food resource that contains soy isoflavones and its content is nutritionally meaningful. Soy isoflavones are a type of secondary metabolites formed during the growth of soybeans. Improvement, its treatment method and planting method are usually studied, but there is no further research on the storage method of soybean, and the existing technology shows that with the increase of storage time, the content of isoflavones in soybean will gradually decrease. The average content of isoflavones will be reduced by about 57.1% after one year, and the storage temperature has little effect on the content of soybean isoflavones. Therefore, further research on soybean storage methods is needed

Embodiment 1

[0015] A storage method for slowing down the reduction rate of isoflavone content in soybeans, characterized in that it includes the following content:

[0016] (1) Thoroughly dry the harvested soybeans on the pods and then thresh them until the water content is 18-20%;

[0017] (2) Set up a sealed container. The sealed container is divided into a storage layer and a smoking layer by a partition plate. The middle part of the partition plate is a metal gauze for storing soybeans, and the upper part is used as a storage layer for storing soybeans; Below is the smoke layer, which is used for burning the mixture, the weight of the mixture is 1-2% of the weight of soybeans; the water content of each raw material of the mixture is 5-8%, including by weight: 10 parts of walnut leaves , 5 parts of prickly ash shells, 2 parts of red pepper; the mixture is put into the smoked layer after being ignited, and the airtight container is kept sealed for 2 days; after completion, the airtight ...

Abstract

The invention belongs to the technical field of agricultural storage, and particularly relates to a storage method for retarding the reduction speed of isoflavone content in soybeans. The storage method comprises several steps of obtaining dried granules, performing sealed smoking, performing air conditioning treatment and performing storage. Compared with the prior art, the storage method has the following advantages that fatty acid in the soybeans can be reduced by the storage method, after the soybeans are preserved for 4 years or above, the situation that the preserved soybeans are free from the phenomena that parts close to embryos, of cotyledons, become red, liquid immersion and reddening can be guaranteed, the nondestructive rate of the appearances of the soybeans which are preserved for five years reaches 96.2%, the isoflavone content in the soybeans is slowly reduced, the isoflavone content in the soybeans preserved for five years is reduced by about 53% than that in the soybeans preserved for one year, and the storage method has definite popularization significance.
