WebAug 27, 2015 · Curdling Milk Is a Matter of pH. Acidifying milk — essentially lowering its pH — causes the milk proteins, like casein, to unwind and unfold in a process known as protein denaturing. The unfolded proteins are then free to interact with each other and clump together in a way they could not do when they were properly folded.
