 Select yellow-skinned soybean grains with full grains, high germination rate, and no damage, disinfect them with 1% sodium hypochlorite by volume, put them in clear water with a mass ratio of water to yellow-skinned soybeans of 1:4, and soak them at 30°C for 5 hours ; put the soaked yellow-skinned soybean grains into a germination machine, and germinate them in the dark at 25°C for 2 days. The culture medium was replaced every 24 hours. The phytic acid degradation rate in the prepared yellow-skinned soybean sprouts was 45%, and the GABA content reached 350mg / 100g DW.
 The method of selection and disinfection of green-skinned soybean grains is the same as in Example 1. Put the sterilized green-skinned soybean grains in clean water with a mass ratio of water to green-skinned soybeans of 1:3, and soak at 30°C for 6h; Light germination was performed for 3 days. During this period, 2 mmol / L GABA aqueous solution was used to spray for 3 minutes every 1 hour. The spray flow rate was 200 mL / min, and the culture solution was replaced every 24 hours. The phytic acid degradation rate in the prepared green-skinned soybean sprouts was 65%, and the GABA content reached 405mg / 100g DW.
 The method of selection, disinfection and soaking of black-skinned soybean grains is the same as in Example 1. Put the soaked black-skinned soybean seeds into a germination machine and germinate them in the dark at 28°C for 4 days. During this period, spray with 5mmol / L GABA aqueous solution for 2 minutes every 1 hour, and the flow rate of the spray liquid is 150mL / min. Replace every 24 hours A culture medium. The phytic acid degradation rate in the prepared black-skinned soybean sprouts was 75%, and the GABA content reached 420mg / 100g DW.
