The present investigation was conducted to figure out the releasing pattern and rate of five phthalates from the plastic bottles into the bottled beverages of fermented milk, fruit juice, and soft drink. The studied phthalates were di-methyl phthalate (DMP), di-ethyl phthalate (DEP), di-n-butyl phthalate (DBP), bis(2-ethyl hexyl) phthalate (DEHP), and di-n-octyl phthalate (DnOP). Phthalates were determined in fifty-four samples (eighteen samples from each beverage type) at the beginning, middle, and end of the shelf-life period in two different bottles sizes for from each beverage type. The resulted limits of detection and quantification for phthalates were in the range of 6.5±2.5 and 20±5 (ng), respectively. Recovery percentages ranged from 75.77±3.06 to 82.95±3.28 (%) in fermented milk, 77.68±4.54 to 80.51±3.06 (%) in fruit juice, and 80.09±5.57 to 88.70±6.72 (%) in soft drink. DnOP was the major detected compound in all the tested beverages, which had the highest concentrations (0.52 – 0.82 ppm) and releasing rates (85.5 – 2116.7 µg week-1) followed by DEHP in fermented milk, DMP in juice, and DBP in soft drink samples. The released phthalates in the big bottles were significantly higher than in the small bottles. The highest values of total phthalates for the three beverages were lower than the tolerable daily intake (TDI) for an adult person by 3 -135 times, which means that the detected amounts of phthalates in the three beverages were within the safe limits. © 2017 @ author (s).
