Mongolian nomads raise sheep, goats, cattle, horses and camels, and milk from these domestic animals is used to make various dairy products. Camels are raised in only a few areas of Mongolia, and there have been few reports on camel's milk and products made from camel's milk by nomads in Mongolia. We therefore carried out a survey on camel's milk and camel milk products in Mongolia. Analysis of camel's milk and cheese (Mongolian nomad called aaruul) made from camels' milk showed that the fat content of camel's milk is higher than that of milk from cows raised by Mongolian nomads. Milk from cows, sheep and goats is used for manufacturing dairy products after fat has been removed from the milk, but products are made from camel's milk without removal of the fat. Aaruul produced from camel's milk was found to have less water content and higher contents of protein, fat and calcium. An alcoholic beverage is also made by fermenting camel's milk. Raw wild plants are sometimes added to camel's milk during the process for producing aaruul. Aaruul made from camel's milk is very hard, but it was found that aaruul made from camel's milk was crushed more quickly by application of pressure of a tensile tester than was aaruul made from cow's milk. The difference in stress strain curve between camel's aaruul and cow's one is dependent on the content of fat.
