[0026] Take 300g of soybeans and grind them in a soybean grinder, filter to obtain soybean meal, mix distilled water and soybean meal at a mass ratio of 10:1 to obtain a soybean meal suspension, and adjust the concentration of the soybean meal suspension with a 5% sodium hydroxide solution. The pH is 8.5, stirred at room temperature for 1.5 hours to obtain an alkalized solution; put the alkalized solution in a centrifuge, centrifuge at a speed of 4000r / min for 15min, separate to obtain a supernatant, and adjust the upper layer with hydrochloric acid with a mass fraction of 2%. The pH of the supernatant was 4.5, and the acidified solution was obtained. The acidified solution was placed in a centrifuge and centrifuged at a speed of 4000r / min for 15 minutes to obtain the lower protein precipitate; , and then add half of the above protein precipitation to the three-necked flask, heat up to 70°C, start the stirrer, and keep stirring at a speed of 150r / min for 1.5h to obtain the reac...

[0028] Take 350g of soybeans and grind them in a soybean grinder, filter to obtain soybean meal, mix distilled water and soybean meal at a mass ratio of 10:1 to obtain a soybean meal suspension, and adjust the concentration of the soybean meal suspension with a 5% sodium hydroxide solution. The pH is 9.0, stirred at room temperature for 1.7 hours to obtain an alkalized solution; put the alkalized solution in a centrifuge, and centrifuge at a speed of 4500r / min for 17min to separate the supernatant, and adjust the upper layer with 2% hydrochloric acid The pH of the supernatant was 5.0, and the acidified solution was obtained. The acidified solution was placed in a centrifuge, centrifuged at 4500r / min for 16 minutes, and the protein precipitate in the lower layer was separated; 850mL of sodium hydroxide solution with a mass fraction of 25% was added to the three-necked flask , then add half of the above protein precipitation to the three-necked flask, heat up to 75°C, start the a...

[0030] Take 400g of soybeans and grind them in a soybean grinder, filter to obtain soybean meal, mix distilled water and soybean meal at a mass ratio of 10:1 to obtain a soybean meal suspension, and adjust the concentration of the soybean meal suspension with a 5% sodium hydroxide solution. The pH is 9.5, and stirred at room temperature for 2.0 hours to obtain an alkalized solution; put the alkalized solution in a centrifuge, centrifuge at a speed of 5000r / min for 18min, separate to obtain a supernatant, and adjust the upper layer with a mass fraction of 2% hydrochloric acid The pH of the supernatant was 5.5, and the acidified solution was obtained. The acidified solution was placed in a centrifuge and centrifuged at a speed of 5000r / min for 18 minutes to obtain the lower protein precipitate; , and then add half of the above protein precipitation to the three-necked flask, heat up to 80°C, start the stirrer, and keep stirring at a speed of 200r / min for 2.0h to obtain the reacti...
