The pyrethroids and carbamate pesticides in apple juice were treated by 60Co-γ irradiation. The effect of irradiation dose on degradation rate of pesticides and changes of main chemical and physical indexes of apple juice were researched on system. The result shows that 6Co-γ irradiation can degrade both pyrethroids and carbamate pesticides effectively: when the irradiation dose was 9kGy, the degradation rate of pyrethroids is Permethrin 65.72%, Cyfluthrin 94.14%, Flucythrinate 72.41% and Deltamethrin 67.84%; when the irradiation dose is 7?kGy, the degradation rate of carbamate pesticides is Lannate 61.64%, Primicarb 76.55% and Carbofuran 63.17%. 60Co-γ irradiation could affect main chemical and physical indexes of apple juice to some extent, the soluble solid concentration and the total sugar content decrease slightly, the total acid content increases slightly, the transmittance and the color value significantly increase.
