This result was parallel to the studies of Chavarri et al. (2010) when quercetin was used in microencapsulation of L. gasseri and B. bifidum. The enhanced growth of L. acidophilus FTDC 8033 and Lactobacillus sp. FTDC 2133 was also observed in soymilk containing FOS, which was higher than 107 cfu mL_1 (Yeo & Liong, 2010)
