Onion powder, irradiated at average doses of 15, 950, and 1360 krad, was investigated using the Salmonella/mammalian‐microsome mutagenicity assay and the in vivo sister chromatid exchange (SCE) test. Cold‐water and hot‐water extracts of nonirradiated and irradiated onion powder did not show any mutagenic effect when tested with or without metabolic activation in the Ames test. Neither were differences between irradiated and unirradiated onion powder observed in the SCE test.
