Toxic substances content in different varieties wheat flour

The purpose of the study is to analyze the content of mycotoxins and heavy metals for the safety of wheat flour of different varieties. The results of the study of the content of toxic substances (mycotoxins, heavy metals) in wheat flour of different varieties are presented. The objects of the study were samples of wheat flour of different varieties (higher, first and second). Detection and quantitative determination of mycotoxins (alphatoxin B1, deoxynivalenol, zearalenone, toxin T-2) was performed by gas-liquid chromatography. The content of heavy metals and their compounds in food products was determined by the atomic absorption method. Statistical data processing used correlation analysis, as well as Friedman's rank analysis of variance (Friedman test) with the calculation of Kendall's coefficient of concordance. Studies have shown that premium flour is of high quality and does not contain mycotoxins; flour of the first grade contains mycotoxin - alfatoxin B1; flour of the second grade contains mycotoxins - alfatoxin B1 and toxin T-2, the amount of which does not exceed the MPC. The lowest content of heavy metals was determined in premium flour, which indicates its high quality. Most of them are in flour of the second grade, although it also does not exceed the MPC.
