Patent ID: 11805790

Abstract:
The present invention provides a zymolytic rice protein powder with low granular sensation, and a method for preparing the zymolytic rice protein powder comprising the following steps: (1) pretreatment of rice residue after sugar production; (2) high temperature extrusion pretreatment; (3) refining treatment; (4) wet crushing; (5) controlling zymolysis; (6) terminating zymolysis; (7) microjet treatment; (8) spray drying; (9) subsequent crushing. The protein content of the zymolytic rice protein powder in the present invention is more than 80%; the fat content thereof is less than 3%; the water content thereof is less than 5%; and the nitrogen solubility index thereof is more than 30%. The molecular weight distribution of the soluble protein is as follows: the proportion thereof with a molecular weight of less than 2000 Da is more than 70%.
