As a result of these studies, the composition of the reaction mixture was optimized for the detection and quantification of GE potato event AV43-6-G7 in food. Oligonucleotide primers and fluorescent probes were selected. The compositions of reaction mixtures and temperature-time parameters of PCR were tested 2.5-fold reaction buffer for PCR-RT in the presence of ROX (carboxy-X-rhodamine), specific to the GE component primers (AV43-6-G7-f/AV43-6-G7-r) and target taxon (GRF3/ GRR3) at 300 nM/300 nM and 100 nM/100 nM, probes at 200 nM and 200 nM, respectively; bovine serum albumin - 0.04%; MgCl2 - 3.5 mM, deoxynucleoside triphosphates - 0.3 mM, as well as the temperature-time profile of the reaction (initial denaturation of 95 °C - 5 min, followed by 45 cycles 95 °С - 20 sec, 58 °С - 20 sec, 62 °С - 40 sec). Conclusion. The validity of the developed method is confirmed by laboratory studies and testifies to its reliability.Tropane alkaloids (TA) are metabolites of various plant species in the families Brassicaceae, Solanaceae and Erythroxylaceae. Seeds of these weeds are found in flax, soy, sorghum, millet, sunflower, buckwheat and food products obtained from them, in herbals used as a part of food supplements and herbal teas. Despite the fact that the contamination of grain seeds by various parts of weeds reduces by sorting and clean up, a certain amount of TA gets into processed foods. An analysis of the consumption of TA with all types of foods, conducted by the European food safety Agency (EFSA), showed that TA intake with ration of various population groups can exceed the established level of single safe intake (ARfD) - 0.016 μg/kg of body weight (by 11-18% for adults, and by 5-25% for children depending on the age). The aim of the research was to justify the need to introduce regulations for the safe content of TA in grain products. Material and methods. The study process used hygiene, analytical meth
