The chemical composition and factors affecting the rennet coagulation of camel's milk were studied in comparison to cow's and buffaloe's milk. The total solids of camel milk was slightly higher while its fat and protein content were slightly less than that of cows' milk. Camel's milk had less casein and slightly higher whey proteins than cow's milk. The increase in chymosim   concentration, addition of increasing concentration of Ca⁺⁺, decrease of pH and increase in temperature enhanced the coagulation of camel's milk in a similar way to cow's milk. However in all cases the rennet coagulation time ( RCT ) of camel's milk was higher than that of cow's and buffaloe's milk.
