Examples
Embodiment 1
[0023] (1) Seed soaking and germination
[0024] Select full-bodied tartary buckwheat grains, put them in a container, add water, and soak at 25°C for 3 hours. Spread the soaked grains evenly on a shallow dish covered with wet gauze at the bottom, put them into a 21°C incubator and germinate in the dark for 20 hours, and spray water into the shallow dish every 12 hours during this period to ensure the humidity.
[0025] (2) Short-wave ultraviolet UV-C irradiation and germination
[0026] In the ultra-clean workbench, use UV-C ultraviolet lamp (253.7nm, irradiance intensity 78μW / cm 2 ) to irradiate the germinated grains for 25 minutes, then put them into an incubator at 21° C. to continue to germinate for 48 hours in the dark, take them out, dry them at 50° C., shell them, and crush them to obtain tartary buckwheat products with increased total flavonoid content.
[0027] (3) Determination of total flavonoids content in tartary buckwheat:
[0028] The tartary buckwheat flour...
Embodiment 2
[0030] (1) Seed soaking and germination
[0031] Select full-bodied tartary buckwheat grains, put them in a container, add water, and soak at 20°C for 7 hours. Spread the soaked grains evenly on a shallow dish covered with wet gauze at the bottom, put them into a 21°C incubator and germinate in the dark for 20 hours, and spray water into the shallow dish every 12 hours during this period to ensure the humidity.
[0032] (2) Short-wave ultraviolet UV-C irradiation and germination
[0033] The method is the same as in Example 1, and the total flavonoid content of the product is 2.837%, which is about 68% higher than that of the control.
Embodiment 3
[0035] (1) Seed soaking and germination
[0036] Select full-bodied tartary buckwheat grains, put them in a container, add water, and soak at 25°C for 3 hours. Spread the soaked grains evenly on a shallow dish covered with wet gauze at the bottom, put them in a 25°C incubator and germinate in the dark for 20 hours, during which time spray water into the shallow dish every 12 hours to ensure humidity.
[0037] (2) Short-wave ultraviolet UV-C irradiation and germination
[0038]The method is the same as in Example 1, and the total flavonoid content of the product is 2.803%, which is about 66% higher than that of the control.
