In our third extraction experiment, we treated an oil containing
152 mg/kg total aflatoxins using 50% ethanol solution prepared from
HPLC grade ethanol. The oil: solvent ratios (g:ml) of 1:3, 1:2, 1:1,
5:3, and 5:1 were used. For all extraction experiments, the oil and
solvent were hand shaken for 1 min. A clean phase separation was
observed following approximately 10 min, after which 25 g of oil
were removed for aflatoxin analysis.
