  • Process for producing soy bean milk
    Patent number: 4971825
    Abstract: This invention is a process of producing soy bean milk in which soy beans are crushed in an aqueous hot medium and then the crushed soy beans are maintained at a high temperature in the aqueous hot medium.Since crushing soy beans were performed in the aqueous hot medium instead of grinding, the decrease in the protein extraction rate caused by subsequent high temperature-maintaining was able to be prevented, with lipoxidase or both lipoxidase and trypsin inhibitor being substantially deactivated.
