The aim of this study was to evaluate the adsorption and biological properties of nanocellulose coated with free fatty acids (NCCFFAs). At first, nanocellulose was synthesized by acid hydrolysis, and then separately coated with different free fatty acids (FFAs), including lauric acid, alpha linoleic acid, oleic acid, and palmitic acid. Next, the serial concentrations of NCCFFAs (1, 10, 100, and 1000 mu g/mL) was separately added to fumonisin B1 (FBI) at 1000 mu g/mL, and separately incubated at 37 degrees C for 1, 2, and 3 h. Then, the percentage of adsorption was calculated. In the next experiment, the viability of mouse liver cells was measured when they exposed to serial concentrations of NCCFFAs, FFAs, and FBI. This study showed that the increase of incubation time and concentration of NCCFFAs led to increase of FBI adsorption. Although FFAs and NCCFFAs had no remarkable toxicity, the high toxicity was observed for FB1. Importantly, the toxicity of FB1 was highly decreased, when incubated together with FFAs or NCCFFAs. These novel adsorbents, NCCFFAs, can be used together with different foodstuffs to remove FB1. (C) 2015 Elsevier B.V. All rights reserved.
