REMOVAL OF AFLATOXIN B1 TOXICITY BUT NOT MUTAGENICITY BY 1 MEGARAD GAMMA RADIATION OF PEANUT MEAL

Abstract
The toxic and mutagenic effects of gamma‐irradiated peanut meal contaminated with aflatoxin B1 were studied in Salmonella typhimu‐rium strain TM 677, using forward mutation to 8‐azaguanine resistance. After treatment with 5 to 10 M‐rad gamma radiation, the contaminated peanut meal lost its toxic and mutagenic properties. Irradiation at 0.1 to 1.0 M‐rad removed 75–100% of the toxicity but not mutagenicity.
