Raw Milk vs Pasteurized Milk

The difference between Raw Milk and Pasteurized Milk is that Raw Milk is a less safe option when compared to Pasteurized Milk. RAW Milk also has some things that are not present in Pasteurized Milk, such as Lipase and Pathogenic Bacteria due to the heating process. And for the same reason, Pasteurized Milk has a longer shelf life in comparison. Except these some properties of Pasteurized Milk also changes.

Raw Milk is the milk that does not go under the process of heating for killing several bacteria to make it safer for consumption. It is also known as unpasteurized milk. Due to heat, few important nutrients inside the milk are destroyed, which is not in the case of raw milk. Its taste and color remain the same.

Pasteurized Milk is when cold raw milk is undergone through a process of heating. It results in terminating harmful bacteria present in the milk that can cause food poisoning or some allergy. After heating, the milk can be preserved for a longer duration, and it also comes in several forms.

What is Pasteurized Milk?

Following are the benefits of consuming Pasteurized Milk:
