Abstract
|
:
|
A method is described for removal of aflatoxin from groundnuts by extraction with methoxymethane (dimethylether) at room temperature in an autoclave or in pressure-tight columns. Contaminated groundnuts are pulverized to pass through a 12 mesh screen, and extracted in stainless steel columns at approximately 6 kg/cm pressure. The extract can be used for preparation of groundnut oil, as aflatoxin is inactivated during refining, and methoxymethane is easily removed from the defatted product because of its low boiling point. The following compositions were obtained for raw and methoxymethane-treated groundnut samples, respectively : crude fat 54.8 and 0.1 percent : crude protein 19.7 and 54.7 percent : and total aflatoxins 1000 and 2.25-3.25 ppb. Duckling feeding tests showed no toxic effects of methoxymethane-treated groundnut powder.
