摘　　要：目的对纤维素纳米纤维的制备及其在食品包装领域的研究进行综述,以期为食品包装材料的发展提供理论支持。方法总结近几年纤维素纳米纤维的不同加工制造方法,关注食品包装材料的气体阻隔性能、抑菌性能、紫外线阻隔性能、疏水性能和新鲜度监测性能等,阐明纤维素纳米纤维在食品包装中的研究进展。结果可以通过化学法、化学法结合机械法和酶法等方法制备纤维素纳米纤维,但均存在产率低、能耗高、尺寸分布不均匀等问题。纤维素纳米纤维可以应用于气体阻隔、抗菌、防紫外线、疏水及智能包装材料,现阶段的纳米纤维制品很难兼顾多功能性。结论纤维素纳米纤维食品包装材料有望取代石油基塑料包装,在食品包装领域具有较大的应用前景。The work aims to review the preparation of cellulose nanofibers(CNFs)and their applications in food packaging,to provide theoretical support for development of food packaging materials.Different manufacturing methods of CNFs in recent years were summarized.This work focused on the gas barrier performance,antimicrobial properties,UV barrier function,hydrophobicity and freshness monitoring property of food packaging materials,and illustrated the research progress of CNFs in food packaging.The results indicated that CNFs could be fabricated by chemical method,chemical method combined with mechanical method,and enzymatic method,but there were some problems such as low yield,high energy consumption and uneven size distribution.CNFs could be used as gas barrier,antibacterial,UV protection,hydrophobic and smart packaging materials.However,the current nanofiber products were difficult to combine versatility.In summary,cellulose nanofibers-based food packaging materials are expected to replace petroleum-based plastic packaging,and have a great prospect in food packaging.
