摘要:The aim of this work is to determine the sodium benzoate, potassium sorbate , nitrate and nitrite contents of commercially available dairy products in Turkey. Seventy-four per cent samples of strained yoghurt, seventy per cent samples of kasar cheese, eighty-five per cent samples of tulum cheese and eighty per cent samples of ayran had sodium benzoate. All cheese samples had potassium sorbate levels inside the legal limits (1000 mg/kg in the sample). All values for nitrates and nitrites that have been found were fairly low. According to Turkish Food Codex, the presence of sodium benzoate and potassium sorbate (except cheese) in dairy products is prohibited. It is clear that new training and checking programs for the most of dairy producers are necessary.
