curdling
Quick Summary
Curdling is a crucial step in dairy production, particularly in cheese making. It involves the separation of milk proteins, primarily casein, into solid curds and liquid whey. This process is typically initiated by adding lactic-acid-producing bacteria and rennet to high-quality milk. The bacteria convert lactose into lactic acid, and rennet, an enzyme, aids in coagulating the casein. Some cheeses, like cottage cheese, are produced solely through acid coagulation. Curdling is essentially a form of food preservation through milk fermentation.123

cheese makingInoculation and curdling…of solution—a process known as curdling, or coagulation. Coagulated casein assumes a solid or gel-like structure (the curd), which traps most of the fat, bacteria, calcium, phosphate, and other particulates. The remaining liquid—the whey—contains water, proteins resistant to acidic and enzymatic denaturation (e.g., antibodies), carbohydrates (lactose), and minerals.
