Physicochemical and bioactive modifications of lotus root polysaccharides associated with probiotic fermentation.

The physicochemical properties and bioactivities of lotus root polysaccharides (LRP) were investigated by examining the effects of probiotic fermentation. Five polysaccharides, namely LRP, LRP-Pl, LRPRh, LRPPa, and LRPAc, were extracted from unfermented and fermented lotus roots using Lactobacillus plantarum, Lactobacillus rhamnosus, Lactobacillus paracasei and Lactobacillus acidophilus, respectively. The results revealed that the yield of LRP-Ac (3.
