Determination of Polycyclic Aromatic Hydrocarbons Level in Commercial Turkish Milks
Journal Title: Cumhuriyet Science journal - Year 2018, Vol 39, Issue 3
Abstract
In the present study, the presence of polycyclic aromatic hydrocarbons (PAHs) in commercial Turkish Milks was investigated. A total of 27 samples consisting of raw milk (n = 2), pasteurized milk (n = 5), UHT milk (n = 17) and also plant milk (n = 3) were analyzed for four EU marker polycyclic aromatic hydrocarbons (PAHs) by using a reversed phase high-performance liquid chromatography with fluorescence detection (HPLC-FLD).The method was in house validated using the validation parameters such as linearity, precision (repeatability and intermediate precision), limit of detection (LOD) and limit of quantification (LOQ), recovery percentages, and also measurement uncertainty. The mean concentrations of the sum of 4 EU marker PAHs were found 0.10 ±0.06 µg kg-1, 0.71 ±0.33 µg kg-1, 0.84 ±0.57 µg kg-1 and 0.20 ±0.28 µg kg-1 for raw, pasteurized, UHT whole and plant milks, respectively. The analyzed milk samples did not exceed the maximum limits of 1.0 µg kg-1, that was regulated for both BaP and 4 EU marker PAHs (4 PAHs) by the European Union.
