Abstract

Background and purpose: Today, due to improvement and progress of human knowledge in food industry, plastic coatings such as PET (polyethylene terephthalate) that has unique characteristics are widely used for food and beverage packaging such as water and doogh. Phthalate esters are used in order to improve flexibility, efficiency and sustainability of materials. Chronic exposure with such materials play a role in incidence of many diseases and cancer in human. The aim of this study was to investigate the presence and concentration of phthalates in different brands of doogh. Materials and methods: In this study, we synthesized multi-walled magnetic carbon nanotubes using iron oxide. Then, the synthesized magnetic nanotubes were used for absorption and extraction of phthalate esters from doogh matrix. After sample preparation, the concentration of each phthalate esters was measured by GC-MS. Results: Concentration of phthalate esters in all samples were found to be lower than the standard levels but DEHP had the highest concentration. Statistical analysis showed no significant differences between the concentration of phthalate esters in different brands and storage time of doogh. Conclusion: According to these findings and low concentration of each phthalate ester compared with standard levels in different types of doogh, it has no health effect on consumers. © 2017, Mazandaran University of Medical Sciences.
