The concentration of aflatoxin in extracted oil was on average 10% of that in un-extracted oil which, in turn, had a concentration that was only 5% of the original contaminated peanuts. Therefore, aflatoxin concentration in the final product was 99.5% less than that found in the original peanuts, even without pre-filtration. Our extraction experiments testing laboratory-grade ethanol and clarin provide evidence that the latter can serve as a low-cost alternative to effectively reduce aflatoxin concentrations in oil pressed from high aflatoxin peanuts.
