Why Does Milk Curdle In The Refrigerator?

If you’ve ever opened your fridge and found your milk had turned into a lumpy, sour mess, you’re not alone. It is a common problem that can be annoying and hard to understand. So, Why does milk curdle in the refrigerator? where it is supposed to be kept?

Milk can go bad in the fridge for a number of different reasons. First, milk is a dairy product, and proteins in dairy products break down over time. Since heat speeds up this process, when milk is chilled, the proteins have more time to break down. They will break down over time, though, which will make the milk thicken and smell sour.

Milk can also go bad in the refrigerator because of bacteria. Bacteria like warm, moist places to live, so the refrigerator is a great place for them to grow. If there are already bacteria in the milk when it goes in the fridge, they can grow quickly and make the milk curdle.

If milk is kept in a container with no air holes, it can turn sour. This is because milk goes bad faster when it doesn’t get enough oxygen. If your milk starts to get thick and smell bad, put it in a container with a loose lid so it can air out.
