摘　　要：鸡蛋的新鲜度指标主要包括感官指标、气室高度、哈氏单位、pH值、蛋黄指数、蛋的比重和挥发性盐基总氮等,传统检测方法只能部分抽检,效率较低。文章综述了可见/近红外光谱、机器视觉、电子鼻、介电特性、低场核磁等无损检测新技术在鸡蛋新鲜度中的应用,分析了各项技术的优缺点。重点分析了用低场核磁检测鸡蛋品质存在的问题,探讨通过分析鸡蛋弛豫谱线和断层扫描图像建立低场核磁预测新鲜度的数学模型,更好地实现低场核磁无损检测鸡蛋新鲜度。Egg freshness indexes mainly include sensory indicators,air cell height,Haugh unit,pH value,yolk index,specific gravity of eggs and total volatile basic nitrogen(TVBN)content.Only part samples can be tested by traditional methods,and the efficiency is low.This paper reviewed the application of visible/near infrared spectroscopy,machine vision,electronic nose,dielectric properties and low-field nuclear magnetic resonance(LF-NMR)for new non-destructive testing(NDT)of egg freshness.Advantages and disadvantages of each technology were also analyzed,and the focus was placed on existing problems of LF-NMR application in the egg quality detection.Egg freshness prediction model was attempt to established by analysis of the relaxation spectra and nuclear magnetic resonance imaging for better non-destructive testing of egg freshness with LF-NMR.
