Effect of pasteurization on the residues of tetracycline antibiotics in milk
Original language description
The main aim of this work was to determine the effect of high pasteurization of milk (85oC/3 seconds) on the residues of tetracycline and oxytetracycline. The samples of raw cow's milk, purchased from a vending machine, were spiked with standard solutions of tetracycline and oxytetracycline. The content of the residues of tetracycline antibiotics was measured before and after heating. Pre-cleaned samples were extracted by a Mixed-Mode Solid Phase Extraction technique and analyzed using High Performance Liquid Chromatography/Diode Array Detection. Whereas the residues of tetracycline decreased only by 5.74% and were not significantly different (P 0.05), the residues of oxytetracycline decreased by 15.3% and this distinction was highly significant (P LESS-THAN OR EQUAL TO 0.01). Based on the results of our study, the tetracycline antibiotics were proved to have differences in the thermostability of particular substances at pasteurization temperatures.
