Abstract

This research was carried out to investigate and estimate aflatoxins in hard and soft Syrian wheat, under realistic storage conditions in concrete silos (Dokma) for three consecutive years. Wheat samples were taken after harvesting in 2011 during purchases in Silos Center of Qal’at al-Madiq. The standard samples were classified into two species: hard wheat (grade 2) (S2/) 2) and soft wheat (grade 2) (S4/2). Each wheat species was stored separately in a large cell of 1200 tons. The wheat species included Exsad 65, Duma (a hard wheat), Sham 6 and Sham 8. A sample of 50 gm was used in experiment (every three months) with a total 52 sample. The aflatoxins were analysed via HPLC. The results showed that samples of hard and soft Syrian wheat were free of aflatoxins (after harvest). After 9 months of storage the aflatoxins were detected and continuo to increase significantly (p< 0.05) for all wheat species. At the final storage period the species Sham 6 recorded high level of aflatotoxins (1.895ppb) followed by Sham 8 (1.685ppb), Douma (1.5246ppb) and Exsad 65(1.452ppb).

Key words: Aflatoxins, Wheat Storage, Syrian wheat, HPLC.
