摘要
综述了气/液态氮在食品加工的应用机制与研究进展,主要包括利用其环境调节性、电离性、相变结晶性、气化吸热性的气调包装、低温等离子体杀菌/改性、气体水合物浓缩、液氮速冻技术。简述了氮气和液氮的理化性质,分析了各项技术的应用原理、现状与挑战。其中低温等离子体杀菌/改性和水合物浓缩是新兴技术,需扩展技术研究对象、扩大适用范围、研发稳定的新装备,未来应用前景可观。气调包装和液氮速冻已工业化应用,但由于食品物料的复杂性和消费者需求的升级,这两项技术仍需不断进行改进,而重点在于技术的强强联合、设备多元化与工厂化。
This paper reviewed the application mechanism and research progress of gaseous and liquid nitrogen in food processing,including modified atmosphere package,cold plasma and modification,gas hydrate concentrating,and liquid nitrogen freezing,according to the properties of environment adjustment,ionization,crystallization,and gasification.The physical and chemical characteristics of gaseous and liquid nitrogen were introduced.The application mechanism,current state,and future challenge of the above technologies were analyzed.Cold plasma and modification and gas hydrate concentrating were belonged to novel technique and mainly stay in the lab the research stage,but with the wonderful prospect;the emphasis of future work was to enlarge the research objects,expand the application scope and develop stable devices.Modified atmosphere package and liquid nitrogen freezing have been applied in the industrial process,however,due to the complicated properties of food and upgrade requirements of consumers,both of them still need to be improved,which include the combination of other techniques and diversification and scale of equipment.
