【 摘 要 】

The incidence of the trichothecenes deoxynivalenol (DON), diacetoxyscirpenol (DAS), and T2 toxin (T2) in popcorn was investigated in 90 samples, belonging to 2 commercial and 28 experimental hybrids planted at experimental stations of the Agronomic Institute of Campinas at the locations of Campinas, Mococa, and Capão Bonito, and in 15 samples of popcorn, 9 branded and 6 unbranded, acquired from commercial outlets in the city of Campinas, SP. The samples were analyzed by gas chromatography with flame ionization detector combined with an alumina:carbon cleanup column. The detection limits were 30ng/g for DON, 50ng/g for DAS, and 40ng/g for T2. Five samples were contaminated with DON, four of them commercial and one from an experimental cultivar. The level of contamination in the commercial samples ranged from 30 to 40ng/g. The sample from the experimental cultivar contained 770ng/g DON. DAS and T2 were not detected in any of the popcorn samples analyzed.
