Occurrence of Diethyl Phthalate (dep) in Food Using Different Packaging: Detection and Traceability
Summary
Diethyl phthalate (DEP) migration from flexible plastic packaging into food was detected and traced using a methodology that avoided simulants and organic solvents during sample preparation. Brazil, one of the largest flexible plastic producers, was the study context, with DEP identified as a migrant contaminant of concern particularly for fatty foods.
The objective of this work was the detection and traceability of the occurrence of diethyl phthalate (DEP) migrating from flexible packaging to food. Brazil is one of the largest producers of flexible plastics widely used in food. The evaluation of migrations of contaminants for food, mainly fatty foods, elucidates the possible transmission of diseases through the daily consumption of migrant contaminants from packaging. Throughout an accurate and highly specific methodology, with no use of simulants or organic solvents during sample preparation, the proposal of this study obtained a direct DEP ranking through migration traceability via headspace: HS-GC-MS. Of the 9 samples of flexible packaging and packaged foods analyzed, DEP was identified in 100%, thus confirming its occurrence in foods. Despite the storage conditions: temperature, shelf life, fat content of the products and the manufacturer’s assessment of use. It is urgent to review official standards to promote intense restrictions on the occurrence of DEP in food and encourage the benefits of reflecting daily consumption habits.
