纳米技术在食品科学中的应用研究进展

Research Progress on Applications of Nanotechnology in Food Science

纳米技术是一门研究纳米材料的特性及其应用的新学科,已经迅速发展成为21世纪三大支柱科学领域之一。纳米技术具备促进包括食品行业在内的传统工业快速发展的巨大潜力。综述了纳米技术在食品应用领域中的若干研究热点;着重介绍了其在食品包装材料与营养物运送体系方面的应用,前者包括不可降解性、可生物降解性与可食性纳米复合材料等食品包装材料,后者包括纳米乳剂、脂质体与聚合物纳米粒等营养物运送体系;最后提出了该新领域亟待研究的重要问题和今后的发展方向。

Nanotechnology,the science and technology that focuses on special properties and applications of a material which emerge from nanometer size,is regarded as one of the three most promising technologies of the 21st century.Nanotechnology will accelerate the development of traditional industries including the food industry.This paper expounded several research focuses on nanotechnology used in food,of which,food packaging materials and nutriment delivery systems were introduced emphatically.The former included non-degradable,biodegradable and edible nano-composites,and the latter included nanoemulsions,liposomes,biopolymeric nanoparticles et al..Finally,important problems and future perspective for this new research area were put forward.
