Нygienic assessment of the influence of pesticides on the fatty composition of sunflower seed lipids.

Abstract

Introduction: A necessary component of modern sunflower growing technologies is a reliable system of chemical protection of crops from a complex of diseases and pests. However, the effects of pesticides on the nutritional and biological value of sunflower seeds have not yet been studied. Aim. Evaluation of the influence of plant protection chemicals on the fatty acid composition of sunflower seeds. Materials and methods: study of the effects of pesticides, study of the effects of pesticides on the fatty acid composition (lipid) of sunflower seed by gas-liquid chromatography was studied. Results: It was found that the content of oleic and linoleic unsaturated fatty acids did not differ significantly from the control. The content of linolenic and arachidonic acids was at the level of the control group. A similar pattern was observed in relation to the content of saturated fatty acids, in particular myristic, pentodecanoic, palmitic, margaric, stearic. The total content of fatty acids (unsaturated fatty acids and saturated fatty) selected under different seed protection schemes did not differ significantly from control. Conclusions: It is proved that the application of the investigated pesticides in various schemes of chemical protection of sunflower crops does not affect the nutritional and biological value of the seeds.
