1. A method for detecting the presence of at least one aflatoxin in a crop or crop product,
wherein
the aflatoxin is produced by an aflatoxigenic Aspergillus species, and whereinthe aflatoxigenic Aspergillus species is co-existent with other fungal species in a natural fungal bouquet, the method comprising:
(i) determining a volatile emission profile of the crop or crop product, and(ii) comparing the volatile emission profile of the 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(iii) 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,wherein
the presence of the 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,wherein
the at least one unique volatile indicator species is a member selected from the group consisting of (E)-2-octenal, (E)-2-nonenal, and (E)-2-decenal. |
