[0025]Mix soybean protein isolate and sodium hydroxide solution with a mass fraction of 5% in a beaker at a mass ratio of 1:3, and add distilled water 10 times the amount of soybean protein isolate to the beaker, at a temperature of 88°C and a rotation speed of 400r / Under the condition of stirring and mixing for 50 minutes, the soybean protein gel was obtained. The soybean protein gel was mixed with the aldehyde solution at a mass ratio of 9:1. After standing and aging at room temperature for 26 hours, the soybean protein gel was obtained. The soybean protein gel was pulverized, frozen in liquid nitrogen for 6 minutes, and then vacuum-dried to obtain a protein porous material; the protein porous material and trioctylamine were mixed in a flask at a mass ratio of 1:8, and the mass of the protein porous material was added to the flask. 3 times the amount of oxalic acid, stirred and mixed for 40 minutes at a temperature of 55°C and a speed of 400r / min, then filtered to obtain a p...
