The traditionally made yoghurt (n: 20) and sour buttermilk (n:20) samples which made from ewe milk, were also collected from the same area. Fig.1 shows the preparation operation of yoghurt and sour buttermilk. As indicated, the samples are prepared in a traditional device known as Mashk, which is made from hide (sheepskin) and is used for making butter and buttermilk from yoghurt. This device is also used widely for preservation of fermented dairy products for 10-20 days at temperatures not exceeding 20 C.
