Abstract
The analytical detection methods for the irradiation treatment of food are investigated recently as international projects as well as projects carried out in our country to resolve the problems on the international trade and labelling in the market. Several promising methods such as ESR, thermoluminescence, chemical luminescence, impedance, viscosity, gas-measurement, lipid-volatile hydrocarbon, lipid-volatile cyclobutanone, germination, microbiology and so on were proposed and reviewed on the international research program organized by FAO/IAEA.
