Abstract

|
This study was conducted to investigate the potential prebiotic activity of an extract from yacon tuberous root on the growth of probiotic strains Bifidobacterium and Lactobacillus. Results showed that the amount of fructooligosaccharides per 100 g fresh root was the highest (7.60 g), followed by sucrose (0.72 g), fructose (0.34 g), and glucose (0.26 g). The in vitro culture test of intestinal beneficial bacteria, including Bifidobacterium longum BORI, B. bifidum BGN4, and B. lactis AD011 showed effective growth on the MRS-Yacon medium containing yacon extract, whereas the growth of Lactobacillus acidophilus AD031, L. plantarum BH02, and L. fermentum BH03 did not differ from that of the control groups. In particular, B. longum BORI showed better growth than the control group after 10 h of incubation. These results indicate that yacon can be a natural prebiotic source of fructooligosaccharides, which can exert a prebiotic effect on intestinal microflora by selectively enriching Bifidobacterium.
