摘要
随着石油基聚合物的过度消耗、地球资源的日渐减少,能源枯竭、环境污染等问题逐渐显现。为了解决这些问题,寻求可持续资源、开发低成本材料的研究迫在眉睫。纳米纤维素复合水凝胶在兼具传统水凝胶良好的柔韧性、高比表面积的基础上结合了纳米纤维素具有的独特纳米级结构以及相容性好、可再生、可降解等优点,同时表现出机械增强和许多其他理想的性能,从而被广泛应用于生物医药、组织工程、药物递送等领域,近年来其在食品工业中的研究也逐渐兴起。本文总结了纳米纤维素复合水凝胶的不同制备方法,介绍其在食品活性包装、智能包装和食品安全传感等方面的应用,并对纳米纤维素复合水凝胶未来的发展进行展望,为纳米纤维素复合水凝胶在食品工业中的实际应用提供参考。
With the excessive consumption of petroleum-based polymers and the decreased earth resources,problems such as energy depletion and environmental pollution have gradually emerged.In order to solve these problems,it is urgent to seek sustainable resources and develop low-cost materials.Nanocellulose composite hydrogel combine the advantages of nanocellulose’s unique nanoscale structure,good compatibility,renewability and degradability on the basis of good flexibility and high specific surface area of traditional hydrogel.At the same time,they also show mechanical enhancement and many other ideal properties,so they are widely used in biomedicine,tissue engineering,drug delivery and other fields.In recent years,research on them in the food industry has gradually emerged.This review article starts with a summary of dif-ferent preparation methods of nanocellulose composite hydrogel,followed by an introduction of their applications in food active packaging,intelligent packaging and food safety sensing.At the end of the article,we further predict the future development of nanocellulose composite hydrogel,in order to provide reference for the practical application of nanocellulose composite hydrogel in food industry.
