The quality detection of poultry egg is an important safeguard for food safety and consumer rights.Traditional methods of detection mainly rely on manual labor,which has disadvantages including high intensity of work,low efficiency,and large fluctuations in accuracy.Spectral detection technology has the advantages of fast,safe,non-destructive,so it has developed rapidly in detecting internal quality of poultry eggs in recent years.This article summarizes the progress of near-infrared spectroscopy,visible-near-infrared spectroscopy,hyperspectral imaging technology and Raman spectroscopy in the non-destructive detection of poultry eggs internal quality including freshness,protein content,fat content,blood spot and meat spot,information of fertilization,sex of breeding egg and viability of egg embryo.The characteristics and difficulties of applying spectral detection technology in non-destructive testing of poultry eggs are analyzed.The development trend of spectroscopic technology is prospected.It will provide technical support for supervising the quality and safety of egg industry in China.
