The aim of research was to fabricate nanohybrid nanopapers based on bacterial cellulose (CNF) and chitosan (CHNF) nanofibers by incorporation of iron oxide (Fe3O4) and aluminum oxide (Al2O3) nanoparticles (NPs). The nanopapers were characterized and their efficiency in selective adsorption of free fatty acids (FFA) from sesame oil was investigated. The oil adsorption capacity and NPs loading capacity of CHNF-based nanopapers were higher than CNF-based ones. The selective adsorption capacity of FFA from sesame oil/oleic acid mixture showed that the nanohybrids are more likely to absorb FFA than to triglycerides and the peroxide value of the oil shows no adverse effect on oxidative deterioration of oil. All nanopapers preserved more than 70% of their activity after 5-stage cycle reusing. Generally, the use of nanopapers as an alternative to chemical neutralization method in the removal of FFA from edible oils can be suggested and the Fe3O4-dopped CHNF nanopaper exhibited the best performance.
