The need to control vegetable oils, packaged in PET on the content of phthalates, features of determining phthalates in vegetable oils is shown in the paper. The data on the migration of phthalates from packaging material is given, the need to monitor the content of phthalates in vegetable oils that come into contact with plastic packaging is shown. The procedure of purifying contaminated samples was developed and introduced. Adsorption purification of sunflower oil samples using inorganic adsorbent floricil was used. It is shown that the effectiveness of the proposed solid-phase purification of samples is caused by the need to control "internal laboratory contamination". Principle possibility of determining phthalates and their derivatives by gas-liquid chromato-mass spectroscopy was experimentally confirmed. Based on the research and analysis of scientific and technical literature, necessity to monitor the content of phthalates in vegetable oils for the purpose of food safety and specifying the appropriate control critical points of oil and fat production was proved.
