Why does curdling happen if milk is not kept in the fridge after a delay in boiling it? Know the reason!


We all use milk every day. Along with drinking milk, many people also use it to make tea. But the problem of curdling is also seen in the summer season. That's why it is very important to heat it and keep it in the fridge. But have you ever wondered why milk breaks down? Today we are going to tell you about this.


Milk does not burst quickly at high and low temperatures,

I there is a delay in boiling the milk coming home, then curdling happens. You should know that milk always bursts at room temperature. If the milk is to be used for a long time, then it should be boiled every 4-5 hours or kept in the fridge.


Curdling is also a recognition of its purity. Adulterated milk does not break easily. Pure milk is made up of many things. Milk contains fat, protein, and sugar. For information, let us tell you that the protein present in milk is suspended in a colloidal solution. Small particles of protein float freely inside the milk and are kept at a distance from each other. As long as they stay away, the milk does not break. But when milk is not boiled or kept in the refrigerator for a long time, its pH level starts decreasing.

As the pH level of milk decreases when it comes to room temperature, the protein particles also start coming closer to each other. This makes it acidic. This is the reason for curdling.
