What to add to milk to prevent it from souring: useful tips

Keeping milk fresh and preventing it from souring can be challenging. However, SSPDaily has prepared some proven methods to help extend its freshness.

1. Sterilization or boiling

An effective way to prevent milk from souring is to sterilize or boil it. By treating milk this way, you can extend its shelf life by up to a week. Store sterilized milk in glass or porcelain containers.

2. Sugar

If you want to prolong the freshness of boiled milk, add a small amount of sugar before boiling. This simple addition can help inhibit bacterial growth and delay souring.

3. Salt

Adding a pinch of salt while boiling milk can act as a natural preservative and prevent souring. This method can effectively increase the shelf life of milk.

4. Baking soda

Surprisingly, adding a small amount of baking soda to boiling milk can help prolong its freshness. This tip is useful when you need milk to stay fresh for an extended period.

5. Salt for unsterilized milk

Remarkably, even unsterilized milk can benefit from a pinch of salt in the fridge. Adding a small amount of salt to a bottle or carton of milk after opening it can significantly extend its freshness. However, be sure to add the salt right away, as adding it later may not have the same effect.

6. Mint leaves

Adding mint leaves to the milk container can help prevent souring. The refreshing aroma of mint leaves also adds a pleasant flavor to the milk.
