Abstract

Aflatoxin B1 was added to preparations of groundnut cake flour, groundnut protein isolate or casein at 0.5 mug toxin/g sample. The preparations were suspended in buffer (pH 5.4 or 7.4) and subjected to sunlight for 6 h; some samples were dialysed in light or shade for 6 h. Sunlight destroyed 23-33% of aflatoxin added to groundnut cake or protein isolate, vs. 83-88% of that added to casein. Dialysis results suggested that although both casein and groundnut proteins bound aflatoxin, that bound to groundnut proteins was in some way protected against the effect of sunlight.
