Abstract:
Ammonia has been found to reduce efficiently naturally occurring aflatoxins present in sunflower meal on pilot plant scale. One percent of ammonia detoxified 96.53 +- 2.52% of aflatoxins in 30 min at 100 +- 1oC under 10+- 0.5 psi of steam pressure. The levels of naturally occurring aflatoxins in sunflower meal ranged form 113 ug/kg to 3322 ug/kg. Not much variation was observed in the detoxification process with the increase in flatoxins content. Resultant detoxified product was found to be free of ammonical smell with an average ammonical nitrogen of 0.1% and average moisture content of 9.37%. The aflatoxins detoxified sunflower meal showed to toxic effect towards eff production in layer when incorporated in the rations at an inclusion rate from 8.5 to 15%, as a vegetable source of protein. The pilot-plant process demonstrated the effective way of destroying aflatoxins in sunflower meal.
