Embodiment 1
[0020] A preparation method of cottonseed meal protein powder for reducing phenol in a high-voltage corona electric field, the steps are as follows:
[0021] (1) Cottonseed cake is crushed to pass through a 100 or 110 or 120 or 130 or 140 mesh sieve;
[0022] (2) Take 1 kg of sieved cottonseed cake, add 0.8 kg of water, soak for 3.0 h, add 0.8 g of cellulase and 0.5 g of hemicellulase, mix well, control the temperature at 50°C, and hold for 10.0 h.
[0023] (3) The enzymatically hydrolyzed cottonseed cake is placed in a high-voltage corona field of 40,000 volts for 9.0 hours. The thickness of the cottonseed cake is 10mm, and the distance between the parallel metal wires is 70mm. The distance between the vertically downward metal discharge needles is 70mm, and the distance between the bottom plate and the metal mesh is 110mm. The detoxified cottonseed cake is crushed through 100 sieves, and then spray-dried (spray flow rate 20mL / min, feed temperature 36℃ , inlet air temperatur...
