Nanomaterials for fresh-keeping and sterilization in food preservation

Abstract

Food sterilizing and antistaling technologies are very important to the public's health and safety and have been attracting more and more attentions. In the past several years, new development chance was created by the introduction of nanomaterials to this critical field. Nanomaterials possess lots of outstanding properties, such as unique quantum size effect, large surface area and catalytic properties, which jointly facilitate high effective fresh-keeping, and thus were considered as promising materials in food sterilization and antistale. This review article focuses on the patented applications of nanomaterials as food biocidal agents, bacteriostatic agents, catalysts and carriers for antistaling agents.
