Abstract

Background and Objective: Today with progress and improvement of knowledge of human in the food industry field, plastic coatings owing to their unique properties, is extensively applied for a package of beverages and food like water and milk. Phthalate esters (PAEs) are applied to increase e sustainability, efficiency and flexibility of materials. Chronic exposure to stated compounds has a role in the occurrence of several types of human illnesses and cancer. The purpose of this study is to investigate the presence and amount of phthalate esters in different types of milk supplied in Tehran city by using magnetized nanotube crane with magnetic iron oxide and through GC-MS device. Materials and Methods: In this research, multi-walled magnetic carbon nanotubes were synthesized by applying iron oxide and then synthesized magnetic nanotubes were applied for absorption and extraction of PAEs from the matrix of milk samples. The number of samples is 60 and has been selected from Tehran, which has been repeated twice. After the preparation of sample, by using GC-MS, each PAEs concentration was assessed. SPSS software was used for data analysis (Kruskal-Wallis and Kolmogorov–Smirnov tests). Results: The outcomes of this study indicated the mean of total phthalates and DEHP in all samples was 5.26 (ranged from 2.94-8.39) and 0.97 (ranged from nd-2.05) µg/L, which were lower than the existing standards (DEHP standard in water is equal to 6 µg/L). Conclusion: According to the current results and with regard to the lower concentration of each PAEs compared with the standard levels in different types of Iranian consumed milk, it can be concluded that there is no hazardous effect for consumers.
