  • Patent number: 5082679
    Abstract: An improved method for de-toxifying aflatoxin contaminated foodstuffs is provided by pre-treating the contaminated foodstuff with a wetting agent prior to exposure to the de-toxicant. An aqueous solution of detergent or soap is a suitable wetting agent which can be applied to the foodstuff by spraying or immersion. Ammonia gas is the preferred de-toxicant. Once the wetting agent has been applied, the de-toxification reaction is exothermic so that little or no heat need be added to reach the elevated temperatures that facilitate rapid de-toxification. The process runs at atmospheric pressure in low cost vessels and may be accomplished in times of an hour or less without external heat sources.
