What happens when lemon juice added to milk? When lemon juice is added to milk it curdles, a process of coagulation. The pH of milk is 6.8 and that of lemon is 3.5 due to the presence of citric acid. As the pH of the milk drops upon adding lemon, the milk curdles i.e the casein protein molecules attract one another forming curdles.
What happens if you mix milk and lemon juice? When milk becomes too acidic, like when we add lemon juice or when it goes sour, the negative charge on the casein groupings becomes neutralized. Now instead of pushing each other apart, the casein starts to clump together.
What does putting lemon in milk do? As lemon is citric in nature and milk is acidic, when drops of lemons juice are added to the milk, it increases the acidic property of milk and the PH content of milk becomes low. As a result, the calcium in it results in precipitation of casein and milk gets curdled.
Can lemon mix with milk? When you mix milk and lemon juice, the result is buttermilk— or rather, the homemade version. Another term for it is “soured milk” because of its tart flavor. However, “soured milk” is frequently associated with spoiled dairy. When you add lemon to milk, its citric acid disrupts the milk’s casein micelles.

Why does acid curdle milk?
If you add acid (lemon juice, vinegar, . . . whatever) to milk, the positive hydrogen atoms get attracted to the negative micelles, making them neutral. When milk goes sour, bacteria turn the main sugar in milk – lactose – into lactic acid, which does the curdling.
What happens if you drink curdled milk?
Risks of drinking spoiled milk
It can cause food poisoning that may result in uncomfortable digestive symptoms, such as stomach pain, nausea, vomiting, and diarrhea. You don’t need to worry if you accidentally ingest a small sip of spoiled milk, but avoid drinking it in large — or even moderate — quantities.
What does citric acid do to milk?
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.
Does citrus and dairy make you sick?

If the milk becomes lumpy or gooey after being heated, that’s a sign that it’s gone bad. Milk curdles because the high acidity in the soured milk causes proteins in the milk to bond together, creating lumps. It’s normal for the milk to have a thin skin on top when heated. That doesn’t necessarily mean the milk is bad.

The processes for making many other dairy products such as cottage cheese, ricotta, paneer and cream cheese start with milk curdling.
What is the pH of milk?
Milk — pasteurized, canned, or dry — is an acid-forming food. Its pH level is below neutral at about 6.7 to 6.9. This is because it contains lactic acid. Remember, though, that the exact pH level is less important than whether it’s acid-forming or alkaline-forming.
