脱酸甲壳素纳米纤维膜的性能评估及其应用探索
Performance Evaluation and Application Exploration of Deacidified Chitin Nanofibril Film
摘要
Abstract
In order to reduce dependence on petroleum resources,research on the application of polysaccharide-based materials has become one of the mainstream trends.The chitin nanofibril(ChNF)is a promising building block for fabricating chitin films from aqueous dispersions.In this study,tannic acid(TA)was introduced into the deacidified ChNF film as a cross-linking agent and functional additive.The structure and performance of the deacidified ChNF film were evaluated and its potentials in fruit packaging were explored.The cross-sectional morphology of the film was characterized by a scanning electron microscope,which revealed that the film was densified by deacidification,thereby improving the water resistance.The addition of TA further improved the film's wet-state mechanical property,antioxidant property,UV-shielding property and antibacterial activity,while the film preserved good optical properties.Specifically,the tensile strength of the film with TA reached(145.1±9.3)MPa,and its free-radical scavenging rates were over 95%.Moreover,preliminary experiments demonstrated the potential of the film with TA for strawberry preservation.关键词
