Skimmed milk was fermented with different amounts of 1∼3% Momordica charantia L. powder by a commercial starter culture for 6 h. The total number of viable cells of M. charantia L. yogurt ranged from 7.43 to 8.87 log CFU/mL. The pH and total acid contents of M. charantia L. yogurt were within a range, 3.95∼5.85 and 2.97∼9.62%, respectively. The supplementation of M. charantia L. increased the inhibitory activity of alpha-amylase, alpha-glucosidase, and lipase. 1,1-Diphenyl-2-picrylhydrazyl radical scavenging activity and ferric reducing antioxidant power activity increased with increasing amounts of M. charantia L. powder. These results suggest that a yogurt of M. charantia L. possesses the balanced inhibitory activity of digestive enzymes and antioxidant activity, and is expected to be used as a functional health beverage.
