The phrase ‘homogenized’ appears on milk and yoghurt packages. What is this homogenization, why is it done? What does homogenized milk and yoghurt mean? Let’s see together.

We know that the cream accumulated on the milk is due to milk fat. Milk fat is found in milk in the form of fat globules and in emulsion. The process of breaking these fat globules into smaller oil globules is called homogenization. This process is done in machines called homogenizers.

So what do homogenized milk and yoghurt mean?

First, let me explain the concept of homogenized milk. After the homogenization process, the fat globules, which are divided into small pieces, are dispersed in the milk. In this way, a homogeneous milk is obtained. In addition, fat globules do not come together and collect on the upper surface. Therefore, cream does not form in ready-made milk. Homogenized yoghurts, on the other hand, are made from milk that has undergone homogenization. It is also called skim yoghurt.

Is this yoghurt and milk harmful to health?

When it comes to foods, when we encounter words or definitions that we do not know, we immediately think that they are harmful. However, nowadays, it is possible to reach many sources to research and learn. Homogenization is a purely mechanical process. No substance is added to the ingredient or a reaction takes place. Milk fat is physically broken down into fragments. This situation does not create a harmful situation in terms of health.
