Antihypertensive effect of alcalase generated mung bean protein hydrolysates in spontaneously hypertensive rats

Mung bean protein isolates were hydrolyzed by alcalase and neutrase, respectively, and the angiotensin I-converting enzyme (ACE) inhibitory activities of the enzymatic hydrolysates were determined at different hydrolysis times. The highest ACE inhibitory activity recorded was for a hydrolysate generated by alcalase (IC50: 0.64 mg protein/ml) after 2 h of hydrolysis. A significant decrease in systolic blood pressure was observed in spontaneously hypertensive rats following a single oral administration of this hydrolysate at a dose of 600 mg/kg of body weight.
