Problems solved by technology

Daily consumption of soybeans and their products is certainly a channel for ingesting soybean isoflavones, but the health effects are affected due to insufficient intake. Therefore, it is a good way to separate soybean hypocotyls from soybean seeds for supplementing soybean isoflavones through comprehensive utilization of soybean deep processing. an economically feasible method

Embodiment 1

[0018] Screen 100 kg of mature and plump soybean seeds, add 200 liters of hot water at 83°C to soak for 5 seconds, so that the germination period of soybean seeds can be quickly started, then brew and cool with cold water, and then soak in cold water for 7 hours. The water temperature is 21°C, and the soybean seeds have swollen and are in the initial germination state; the soybean seed coat is peeled off by stirring and rolling at a low speed in an industrial peeling device for 1 minute, and the rotation speed is 40 rpm. Soybean cotyledons are separated, and then stirred and rolled at medium speed by an industrial peeling device for 2.5 minutes so that the two cotyledons in a tightly embraced state are separated, and the soybean hypocotyl is separated and peeled off at a speed of 3000 rpm. The semi-suspended soybean hypocotyl is separated from the soybean cotyledons. The soybean hypocotyl is dried by using a low-temperature drying device, the drying temperature is 45° C., and ...

Embodiment 2

[0020] Screen 100 kg of mature and plump soybean seeds, add 200 liters of hot water at 70°C to soak for 2 minutes, so that the germination period of soybean seeds can be quickly started, then brew and cool with cold water, and then soak in cold water for 6.5 hours. At 20°C, the soybean seeds have swollen and are in the initial germination state; the soybean seed coat is peeled off by stirring and rolling at a low speed for 3 minutes in an industrial peeling device, and the rotation speed is 30 rpm, and the seed coat suspended on the water surface and the soybean The cotyledons are separated, and then the two cotyledons in a tightly hugged state are separated by stirring and rolling for 5 minutes in an industrial peeling device, and the soybean hypocotyls are separated and peeled off at a speed of 600 rpm, and placed in the separation tank again to form half The soybean hypocotyl in the suspended state is separated from the soybean cotyledons. Dry the hypocotyls of soybeans wit...

Embodiment 3

[0022] Screen 100 kg of mature and plump soybean seeds, add 200 liters of hot water at 75°C to soak for 1.5 minutes, so that the germination period of soybean seeds can be quickly started, then brew in cold water to cool down, and then soak in cold water for 5 hours. At 24°C, the soybean seeds have swelled and are in the initial germination state; the soybean seed coat is peeled off by stirring and rolling at a low speed for 2 minutes in an industrial peeling device, and the rotation speed is 200 rpm, and the seed coat suspended on the water surface and the soybean The cotyledon is separated, and then the industrial peeling device adopts medium-speed stirring and rolling for 4 minutes to separate the two cotyledons in a tightly hugging state, and the soybean hypocotyl is separated and peeled off at a speed of 1000 rpm. The semi-suspended soybean hypocotyl is separated from the soybean cotyledons. The soybean hypocotyl is dried by using a vacuum drying device, the drying temper...

Abstract

A process for separating soybean hypocoty includes scalding soybean seeds by hot water for instantaneously stimulating them, soaking in cold water for germinating, peeling, growing seed lobes, separating hypocoty from seed lobes, low-temp drying, and extracting soybean isoflavone, which can be used for preventing and treating the menopathy of menopausal woman, vaginitis, cardiovascular disease and cancer.

Description

technical field [0001] The invention relates to a method for separating soybean hypocotyls in the germination stage by initiating rapid germination of soybean seeds in a dormant state. Background technique [0002] Isoflavones of Soybean (Isoflavones of Soybean) mainly come from the pods of legumes. The content of soybean is high, distributed in the hypocotyl and cotyledons of soybean seeds, the content of isoflavones in the seed coat is very small, and the content of isoflavones in cotyledons is 0.1% to 0.3%, and the content of isoflavones in the hypocotyl is 5 to 10 times that of the cotyledons. Human experiments have shown that soy isoflavones are mainly absorbed in the intestinal tract, with an absorption rate of 10% to 40%, while sprouted soybeans can enhance the absorption of soy isoflavones, with an absorption rate of 20% to 60%. Studies have found that the estrogen-like effects of soybean isoflavones affect the secretion of sex hormones, metabolism and biological ac...
