Abstract
Abstract A simple and rapid extraction procedure, based on a direct extraction introduced by Pons and a single liquid-liquid extraction proposed by Waltking, is described for peanuts and peanut products. Methanol is used as the extracting solvent. TLC, using the system described by Engstrom, yielded satisfactory results. The method is suitable for aflatoxin Bi levels of 8 μg/kg (or higher) in peanut butter and roasted peanut products. Aflatoxin B1 levels down to 3 μg/kg can be detected in raw peanuts and peanut shavings.
