Goats produce only approximately 2% of the world total annual milk supply. Goat milk differs from cow milk from its higher digestibility, alkalinity, buffer-ing capacity, and certain nutritional and therapeutic properties. The composition of goat milk is similar to cow milk, although it has a smaller fat globular size and a whiter color than cow milk, as goats convert all β-carotene into vitamin A. Goat milk fat contains more than 20 volatile branched-chain FA, including 4-methiloctanoic and 4-ethyloctanoic acid, which contribute to mutton-type and goat-type flavor, respectively.It is poor in ca-sein; casein micelles contain more calcium, inorganic phosphorus, and non-centrifugal caseins, they are less solvated, less heat stable, and lose β-CN more quickly than cow milk casein micelles. Ren-neting time for goat milk is shorter than for cow milk, and the weak consistency of the gel explains the low cheese yield
