Embodiment 1

[0028] A method for improving the total flavonoid content of wild soybean bean sprouts, comprising the following steps:

[0029] 1) Wash the wild soybeans and place them in a bean sprouting device (Korite Bean Sprout Machine, CB-A361), add water to submerge the beans by 3-4mm, change the water every 12 hours, and soak for 48 hours at 24°C to obtain preliminary bean sprouts;

[0030] 2) After 48 hours, replace the water in the bean sprouting device with an equal volume of NaCl solution (NaCl concentration: 120mmol / L), replace the NaCl solution every 12 hours, soak at 24°C for 48 hours, and obtain bean sprouts with high total flavonoid content.

Abstract

The invention relates to the technical field of bean sprout preparation, in particular to a method for increasing the content of total flavonoids in wild soybean bean sprouts. The method provided by the invention comprises the following steps: performing first soaking on beans in water for 48-50 hours to obtain preliminary bean sprouts; the preliminary bean sprouts are subjected to second soaking for 46-48 h in a NaCl solution with the concentration being 100-130 mmol / L, and the bean sprouts with the high total flavonoid content are obtained. According to the method disclosed by the invention, the soybeans soaked for a proper time are soaked in the NaCl solution with a proper concentration, so that the total flavone content of the wild soybean sprouts can be obviously improved. Besides, the method provided by the invention not only improves the content of total flavonoids in the wild soybean sprouts, but also has less influence on the ratio of dry weight to fresh weight of the wild soybean sprouts, and has higher total economic value.

Description

technical field [0001] The invention relates to the technical field of bean sprouts preparation, in particular to a method for increasing the total flavonoid content of wild soybean bean sprouts. Background technique [0002] Flavonoids are an important class of secondary metabolites in nature, widely distributed in the plant kingdom, mainly in green plants such as Chinese herbal medicines, fruits and vegetables. The health function of flavonoids is very significant. A large number of studies have shown that total plant flavonoids have antioxidant effects, and can inhibit lipid peroxidation at higher concentrations. It contains phenolic hydroxyl groups as oxygen donors, which can react with free radicals to generate corresponding ions Or molecules, which can terminate the chain reaction of free radicals and can significantly enhance the body's immunity. [0003] Bean sprouts have been a traditional vegetable of our people since ancient times. It is rich in nutrition and has...
