Kaymak is a kind of concentrated cream, which is traditionally manufactured from buffalo or cow's milk in Turkey. It is generally consumed with honey at breakfast and some traditional Turkish desserts. The aim of this study was to determine some chemical and microbiological properties of kaymak. The samples were obtained from different dairy plants producing kaymak from cow's milk and local markets located in Izmir. They were examined for total solids and fat contents, acidity, pH and peroxide values, as well as counts of coliform bacteria, E. coli, yeast and moulds, and Staphylococci.
