In addition to direct damage to crops, reduced quality and yield losses, the infected grains can accumulate mycotoxins (toxic metabolites originating from prior fungal growth), especially deoxynivalenol (D DN). Wheat crops harvested in 2014/2015 in southern Brazil were affected by high levels of Fusarium head blight. In this context, the aim of this study was evaluate the mycotoxicological quality of Brazilian wheat grains and wheat products (wheat flour and wheat bran for D DN. D DN contamination was evaluated in 1,504 wheat and wheat product samples produced in Brazil during 2014. It was determined by high performance liquid chromatograph fitted to a mass spectrometer (LC-MS / MS). The results showed that 1,000 (66.5%) out of the total samples tested were positive for D DN. The mean level of sample contamination was 1047 μg.kg -1 , but only 242 samples (16.1%) had contamination levels above the maximum permissible levels (MPL) - the maximum content allowed by current Brazilian regulation. As of 2017, MPL will be stricter. Thus, research should be conducted on D DN contamination of wheat and wheat products, since wheat is a raw material widely used in the food industry, and D DN can cause serious harm to public health. Keywords: Fusarium; mycotoxins; fungal diseases; scab; fusarium head blight. Practical Application: The paper presents an overview of deoxynivalenol contamination in wheat and wheat products affected by Fusarium head blight. Contamination is compared with the maximum permissible limits set by current law in Brazil in order to warn consumers about the levels of this contaminant found in the study samples. 2017 artículo científico 0101-2061 https://www.redalyc.org/articulo.oa?id=395949992002 en http://www.redalyc.org/revista.oa?id=3959 Ciência e Tecnologia de Alimentos application/pdf Sociedade Brasileira de Ciência e Tecnologia de Alimentos Ciência e Tecnologia de Alimentos (Brasil) Num.1 Vol.37 |
