粮食抗菌抗虫包装研究进展

Advances in antibacterial and insect-resistant packaging for grain

我国是粮食的生产大国,同时也是粮食的消费大国,粮食作物从收获到被消费者购买,最后被消化系统所吸收,是一个相对漫长的过程。如果粮食在包装方面存在问题或者储存方式不当,会造成微生物和储粮害虫的污染,从而影响粮食的营养价值,带来食品安全问题。优异的抗虫抗菌粮食包装,在粮食储存与流通环节中起着十分重要的作用。首先,论述了我国传统粮食包装的变迁及各自的优缺点;其次,介绍了3种粮食新材料包装,包括高阻隔抗菌包装、纳米抗菌包装、气调抗菌包装等新型粮食包装的抗菌抗虫原理、优缺点以及研究进展;再次,针对包装材料对粮食品质的影响进行简单介绍;最后,指出现阶段粮食包装存在的问题,并对未来粮食包装的发展趋势提出新思路。

China is a large country of grain production and consumption.It is a relatively long process from harvesting to being purchased by consumers and finally being absorbed by the digestive system.If there are problems in the packaging of grain or the storage method is improper,it will cause the pollution of microorganisms and stored grain pests,which will affect the nutritional value of grain and bring food safety problems.Excellent insect resistant and antibacterial grain packaging plays a very important role in grain storage and circulation.First,it discusses the changes of traditional grain packaging in China and their advantages and disadvantages;Secondly,three kinds of new material packaging for grain were introduced,including the principle,advantages and disadvantages and research progress of high barrier antibacterial packaging,nano antibacterial packaging and modified atmosphere antibacterial packaging;Then,the impact of packaging materials on grain quality is briefly introduced;Finally,it points out the existing problems of grain packaging at the emerging stage,and puts forward new ideas for the development trend of grain packaging in the future.
