Abstract
Health-promoting effects of vegetable juice (VJ) and fermented vegetable juice (FVJ) were determined. Both juices displayed antioxidant activity against DPPH radical, and ORAC values obtained for both juices were not statistically different. The α-glucosidase inhibitory activities of the VJ and FVJ were not different. However, α-amylase inhibitory effect of the VJ (IC50: 41 μM) was higher than that of FVJ (IC50: 149 μM) (p < 0.05). In vitro bile acid-binding capacity of FVJ was about 4.30 times higher than that of VJ (p < 0.05). Although in vitro ACE inhibitory activity of VJ was below 50%, FVJ displayed ACE inhibition (80.2%) with an IC50 value of 50 μg protein/ml. Even though ACE inhibitory activities of digested and undigested FVJ were similar, there was a 42-fold decrease in the IC50 value of FVJ after small intestinal digestion (p < 0.05). FVJ, diluted by one half, displayed hemagglutinating activity whilst VJ did not display any hemagglutinating activity.
