Screening Method for Zearalenone., Aflatoxin, and Ochratoxin

Abstract

A rapid and sensitive procedure has been developed for detecting aflatoxin, ochratoxin, and zearalenone. This procedure uses a water-chloroform extraction combined with sequential elution of the mycotoxins from a silica gel column. Applicability to a wide variety of products was demonstrated by analysis of 31 different commodities. Three commodities (cottonseed, green coffee, and capsicum peppers) contained serious interferences for all three toxins.
