外文摘要：NOVELTY - Method for detecting the presence of at least one aflatoxin in a crop, preferably almond crop or crop product, involves (a) determining a volatile emission profile of the crop or crop product, (b) comparing the emission profile of crop or crop product to a volatile emission profile of a control crop or crop product that is known or designated as aflatoxin free, and (c) detecting the presence of at least one unique volatile indicator species in the volatile emission profile of the crop or crop product that is not present in the volatile emission profile of the control crop.
USE - The method is useful for detecting presence of at least one aflatoxin in a crop, or crop product. The crop, or crop product is almond crop or cotton. The aflatoxin is produced by an aflatoxigenic Aspergillus species, and the aflatoxigenic Aspergillus species is co-existent with other fungal species in a natural fungal bouquet (all claimed).
ADVANTAGE - The method detects presence of at least one aflatoxin in a crop, or crop product in a reliable manner.
DETAILED DESCRIPTION - Method for detecting the presence of at least one aflatoxin in a crop or crop product, involves (a) determining a volatile emission profile of the crop or crop product, (b) comparing the emission profile of crop or crop product to a volatile emission profile of a control crop or crop product that is known or designated as aflatoxin free, and (c) detecting the presence of at least one unique volatile indicator species in the volatile emission profile of the crop or crop product that is not present in the volatile emission profile of the control crop, where the crop is almond crop, the presence of at least one unique volatile indicator species in the volatile emission profile of the crop or crop product that is not present in the volatile emission profile of the control crop or crop product, indicates that the crop or crop product is contaminated with aflatoxins, and at least one unique volatile indicator species is chosen from (E)-2-octenal, (E)-2-n! onenal, and (E)-2-decenal, the aflatoxin is produced by an aflatoxigenic Aspergillus species, and the aflatoxigenic Aspergillus species is co-existent with other fungal species in a natural fungal bouquet.
