植物纤维素基阻隔性改性材料在食品包装上的应用研究进展

Application of Plant Cellulose-Based Materials with Improved Barrier Property in Food Packaging

解决石油基食品包装造成的环境污染问题,纤维素是理想的替代材料。由于纤维素的高密度氢键使其具有较强的亲水性,提高纤维素的阻隔性刻不容缓。本文介绍植物基纤维素绿色制备的方法,详细阐述其在阻隔性改性方面的措施,为该类材料的生产、加工提供了借鉴;重点收集纤维素基阻隔性包装材料在生鲜食品和加工食品上的应用实例,为高阻隔纤维素包装的实际应用提供了理论依据;最后总结纤维素阻隔性包装目前面临的挑战,希望能为未来的工业化生产增添助力。

Cellulose is an ideal alternative material to solve the environmental pollution problem caused by petroleum-based food packaging.Due to the high-density hydrogen bond that makes cellulose highly hydrophilic,it is urgent to improve the barrier property of cellulose.This paper reviews the green preparation methods of plant-based cellulose,and elaborates the measures to improve the barrier property of the cellulose.This paper focuses on some examples of the application of cellulose-based barrier packaging materials in fresh and processed foods.Finally,this paper summarizes the current challenges faced by cellulose barrier packaging,hoping to provide impetus for future industrial production.
