The nutraceutical properties of Aloe vera have been attributed to a glucomannan known as acemannan. Recently information has published about the presence fructans in but there are no publications acemannan and prebiotic compounds. This study investigated vitro these polysaccharides. Our results demonstrated that from induced bacterial growth better than inulin (commercial FOS). Acemannan stimulated less fructans, much commercial FOS. Using qPCR population human feces fermented bioreactor simulating colon conditions, we found induce an increase Bifidobacterium spp. Fructans produced greater amounts short chain fatty acids (SCFA), while branched-chain (BCFA) did not with increased significantly acetate concentrations. Therefore, both polysaccharides potentials.
