摘要

Milk can be efficiently processed into a variety of dairy foods with a little help from acid-producing bacteria and/or food-grade acidulants. Indeed, milk, an almost neutral fluid with a pH in the range of 6.4 to 6.8, can become hard cheese when it drops about one pH point; a soft, fresh cheese when it drops another; and yogurt when it drops a bit more. Milk is an ideal substrate for the growth of microorganisms. Some are inherently present in milk, while others are selectively added for their specific functionalities, many of which rely on the process referred to as fermentation.
