摘要

Mushroom polysaccharides (MP), including white MP, brown MP, and enoki MP, were incorporated into cellulose nanofiber (CNF). Studies on thermal property, structure, crystallinity, and morphology of CNF-MP films revealed that MP was well interacted with and adsorbed onto CNF. Incorporation of MP significantly (P0.05) increased tensile strength and reduced water vapor permeability of CNF film. CNF-MP films possessed higher antioxidant activity than CNF only or CNF-chitosan film, and the antioxidant activity of released components from CNF-MP films immersed in water was higher than that released from films immersed in methanol. Radical scavenging activity and reducing ability were major antioxidant mechanisms of CNF-MP films. These trends were consistent with the results of total phenolics content released from films and the antioxidant activity of MP themselves. This study demonstrated CNF-MP films may be used as packaging material for preventing oxidation and/or dehydration of food during storage. (c) 2017 Wiley Periodicals, Inc. J. Appl. Polym.
