Results present mean values of six measurements (three cheese-makings and duplicate analyses)±standard error. Mean values of the same age and the same row with different lower case letters (a-c) are significantly different (p<0.05). Mean values of each parameter in the same row of the same type of milk with different capital letters (A, B) are significantly different (p<0.05). SCFFA=short-chain fatty acids (C2-C10), MCFFA=medium-chain fatty acids (C12-C14), LCFFA=long-chain fatty acids (C16-C18:3), TFFA=total free fatty acids
