A novel crude exopolysaccharide (EPS) produced by Lactobacillus plantarum KX041 possessed prominent antioxidant activity which was proved in our previous study. In our present study, the further purifications were conducted to obtain EPS fractions, which were called as EPS-1-1, EPS-2-1 and EPS-3. The structures and conformational characterizations were determined through FT-IR, UV, GC, HPLC, NMR, SEM and Congo red test analysis. The Mw of EPS-1-1, EPS-2-1 and EPS-3 were estimated to be 57,201, 70,734, and 26,387 Da, respectively...
