Hey there, in this question, let's say we are starting with a glass of milk.
00:12
And what i want to do is to add an organic acid to this milk.
00:23
An organic acid doesn't necessarily mean something complex.
00:27
It can be something like lemon juice.
00:32
It could be vinegar, et cetera.
00:38
So any type of organic acid.
00:41
When we do that, there is a protein in milk called casein.
00:53
And the acid interferes with that protein.
00:58
It does what is called denaturing it.
01:02
So it is denatured by the acid, which causes that casein to clump together through a process called curdling.
01:23
So this is also considered coagulation.
01:36
That's what clumping together means, is coagulation.
01:42
So we get these clumps, very much like cottage cheese...
