Analysis on storage quality and risk factors of wheat from different regions and varieties in Xinjiang
Wheat quality is closely related to wheat varieties and risk factors affecting wheat quality.Through taking 100 wheat samples of 10 different varieties in 5 different regions of Xinjiang,the conventional quality indexes,storage quality indexes,pesticide residues and heavy metal contents of different varieties of wheat in Xinjiang were determined to determine the quality indexes of different varieties of wheat and analyze the risk factors affecting the quality of different wheat.The results showed that the detection rate of black embryo grain in wheat was 31%;the detection rates of total arsenic,cadmium and chromium were higher,but the values were within the safety standard range;58 pesticide residues were not detected,indicating that the risk of pesticide residues was low;deoxynivalenol,aflatoxin B1 and zearalenone were not detected.Strict quality control measures should be taken in the process of wheat growth,storage and processing,and quality and safety inspection and monitoring should be carried out in the process of wheat storage and transportation.At the same time,regulatory authorities should continue to strengthen monitoring and management to ensure the quality and safety of wheat.
