In spread cheese nitrate level was between6.988 mg/kg to 37.934 mg/kg, with an average 15.112 mg/kg, in cream cheese nitrate level was between 20.46 mg/kg to 174.20 mg/kg ,with an average 48.32, in mozzarella cheese nitrate level was between 3.49mg/kg to 40.18 mg/kg, with an average 23.17mg/kg, while nitrate level in feeta cheese was between 151.24 mg/kg to 171.20 mg/kg, with an average 158.22mg/kg and in semi soft cheese nitrate level was between 20.59mg/kg to 50.16 mg/kg,with an average 33.55 mg/kg.
