纳米纤维素复合水凝胶的制备及其在食品工业中的研究进展OA

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 flexibil-ity 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 devel-opment of nanocellulose composite hydrogel,in order to provide reference for the practical application of nanocellulose composite hydrogel in food industry.
