【 摘 要 】

A preliminary approach to achieve compatible simultaneous extraction of aflatoxin and residual oil from pressed oil meals was conducted to determine the minimum amount of water to be added to ethanol versus necessary time to achieve complete removal of aflatoxin. Commercial anhydrous, 96, 93 and 90°GL ethanol were utilized in trials with Soxhlet extractors. Commercial anhydrous ethanol did not remove aflatoxin completely and the extraction efficiency in minutes was directly proportional to the amount of water present in the ethanol, as expected. Although 96°GL ethanol was efficient, alcoholic strengths between 96 and 99°GL need be evaluated to improve oil extraction, provided they do not decrease aflatoxin removal efficiency.
