Escopo e aplicabilidade

This standard applies to fresh fruits and vegetables treated with ionizing radiation for the purpose of inhibiting sprouting, preserving freshness, or delaying ripening. It covers products irradiated using 60Co or 137Cs gamma rays, X-rays with energy below 5MeV, or electron beams with energy below 10MeV. It is mandatory for all manufacturers and processors utilizing irradiation on these specified produce categories. It replaces several previous standards including GB 9980-88 and GB 14891.5-94.

Requisitos técnicos

The standard outlines the technical requirements for irradiated fresh produce, starting with raw material selection, which must exclude spoiled or unsuitable items before irradiation. It establishes strict dose limitations, specifying that the overall average absorbed dose must not exceed 1.5kGy, with a dose uniformity ratio of less than or equal to 2. Furthermore, the standard defines sensory requirements, mandating that irradiated fruits and vegetables retain their original color, aroma, taste, and shape without any spoilage or off-odors. It also sets physicochemical limits for pesticide residues and heavy metals. Compliance with these chemical limits requires adherence to referenced national standards for substances like BHC, DDT, and arsenic.

Métodos de ensaio

Testing methods involve evaluating chemical residues and contaminants according to specific referenced GB standards. This includes the determination of BHC and DDT residues following GB 5009.19, organophosphorus pesticide residues per GB 5009.20, fluorine according to GB 5009.18, and total arsenic as specified in GB 5009.11.
