纤维素及其衍生物制作可食性包装膜的研究现状

Research Status of Edible Packaging Film Made from Cellulose and its Derivatives

天然高分子纤维素具有优异的生物兼容性、无毒、易降解等特点。纤维素及其衍生物制作可食性包装的研究一直是研究的热点。针对纤维素及其衍生物(如醋酸纤维素、纳米纤维素、纤维素纳米晶、微纤化纤维素、硫酸纤维素、羧甲基纤维素、甲基纤维素、乙基纤维素和再生纤维素等)的特性,以及在可食性包装膜中的应用现状及潜力进行了综述,并对纤维素基可降解抑菌食品包装的发展方向提出展望。

Natural polymer cellulose has the characteristics of excellent biocompatibility,non-toxic,easy to degrade and so on.The research on the edible packaging of cellulose and its derivatives has been a hot topic.This paper reviewed the properties of cellulose and its derivatives(cellulose acetate,nanocellulosic,cellulose nanocrystalline,microfibrillated cellulose,cellulose sulfate,carboxymethyl cellulose,methyl cellulose,ethyl cellulose and regenerated cellulose,etc.)and their application status and potential in edible packaging films.The development direction of cellulose-based biodegradable and bacteriostatic food packaging was prospected.
