Embodiment 1
[0032] Take 10kg of cottonseed meal and crush it with a particle size of 80 mesh; add 150kg of water, stir for 1 hour at a temperature of 30°C, and centrifuge to obtain the supernatant and filter residue; the supernatant is removed through a microfiltration membrane, and the operating condition is pressure 0.2MPa, temperature 40°C, flow rate 90L / min, to obtain concentrate and filtrate; the filtrate is then concentrated by nanofiltration membrane, the operating conditions are pressure 1.5MPa, temperature 40°C, flow rate 20L / min; Spray-dry the concentrated solution to obtain 0.62kg of oligosaccharides (white powder); and add 150kg of water to the concentrated solution of the slag after water extraction and the microfiltration membrane to dissolve in alkali, adjust the pH to 10, and the temperature to 80°C, stirring 1h; carry out enzymolysis after alkali dissolution, adjust the pH to 7.5, the temperature is 55°C, add 500g of alkaline protease, and enzymolysis for 2h; after the enz...
Embodiment 2
[0034] Take 10kg of cottonseed meal, crush it, and the particle size is 80 mesh; add 150kg of water, stir for 1 hour at a temperature of 40°C, and centrifuge to obtain the supernatant and filter residue; the supernatant is removed through a microfiltration membrane, and the operating condition is pressure The concentration is 0.25MPa, the temperature is 50°C, and the flow rate is 90L / min to obtain the concentrate and the filtrate; the filtrate is then concentrated with a nanofiltration membrane, and the operating conditions are as follows: a pressure of 2MPa, a temperature of 50°C, and a flow rate of 20L / min; The concentrated solution was spray-dried to obtain 0.625kg of oligosaccharides (white powder); and the slag after water extraction and the concentrated solution of the microfiltration membrane were added with 150kg of water for alkali dissolution, and the pH was adjusted to 11, the temperature was 85°C, and stirred for 2h ;After the alkali dissolution, carry out enzymatic...
