Method of preparing fermented crude extract having angiotensin converting enzyme inhibiting activity
This invention is related to a method of preparing a fermented crude extract having angiotensin converting enzyme inhibiting activity. The method comprises the following steps. A material is dried, milled, and then mixed with water in a weight ratio of 1:11 to form a mixture solution. 0.1 vol % α-amylase is used to perform hydrolysis at 95° C. for 1 hour. 0.1 vol % glucoamylase is used to perform hydrolysis at 65° C. for 4 hours. A lactic acid bacterium is added in a culture medium containing the mixture solution to perform fermentation for 24 hours. The culture medium is centrifuged to take the supernatant thereof, and the supernatant is boiled for 20 minutes. The supernatant is filtered to obtain a fermented crude extract having angiotensin converting enzyme inhibiting activity.
