A Study on Relativities of T-Toxin and Fumonisin in Wheat Flours in Iran

Abstract

Wheat is one of the most important grains consumed in the world. Food contamination with toxicogenic moulds increased attention over the last three decades, which impact on food safety. Fumonisins, the TCs and ZEA are hazardous for human and animal health during normal food processing. Therefore, a rapid and sensitive technique for routine assay of mycotoxins in foods is necessary.Attention to this subject that bread is one of the most widely used food substances in cereal series, it is important to continue to monitor the occurrence of these mycotoxins in cereals and cereal products. Since Fusarium species are commonly associated with cereals can produce several secondary toxic metabolites the samples collected from provincial premier and preparation of cell extracts then toxin estimation were done by ELISA (Kits and Rida Screen T-toxin / Fumonisin analysis R-Bio-Pharm GmbH )on the samples so that T-toxin/Fumonisin to be analyzed. According to the amount of fusarium toxins measured in grain and fluor samples comparing to the amount of toxin observed in bread flour maintain compliance found that the amount of FT/FFum(NPar-Wilcoxon Signed Ranks Test for Ftox - FFum;Z; -2.480a,Asymp-Sig; 0.013,Pearson Correlation ;0.266, Sig;0.358)for T-toxin correlations in wheat flour incomparison have no significant correlation despite reverse relations for the both,but not statistically significant was supporting by the Pearson statistical determinations a significant correlation for the two variables in contrast were statistically meaningful in numerical differences(P< 0/05 ). The determinative pollutions of wheat flour samples were in the Mean;28.764 ppb,Range; 30.100 (Min; 11.100,Max; 41.200 ppb),Var; 65.922,Std.Dev.; 8.119,Skewness; -0.614,Kurtosis; 0.590 for T toxin and for Fumonisin (Mean; 21.422 ppb, Range; 5.670 (Min; 19.290,Max; 24.960 ppb),Var; 2.623,Std.Dev.; 1.620;Skewness; 0.712,Kurtosis; 0.209) as statistic definitions were showed a considerable disalignmented correlation specialy at a Pearson Correlation ; 0.408/0.266, Sig;0.358, Sig; 0.001-0.013 values.Thus according to the standard values for feed and food could be serious attention to the cumulative effects of toxins, a serious risk andthat should not be overlooked about the cities and provinces where conducted .The maximum values of found respectively were more than standards 50% up to 100%, so a serious risk are considered.DOI: http://dx.doi.org/10.3126/ijls.v9i5.12703
