High-protein products are on trend. Yogurt and high-protein drinks are extremely popular. But how does the additional protein get into these products?
Young, dynamic, sporty, fit, active: these adjectives all describe an approach to life that many people identify with nowadays. Exercising regularly often goes hand in hand with a healthy diet. One nutritional component in particular has become the focus of attention here: protein. Proteins are key building blocks in our body and are required for the proper functioning of the entire body. Milk is a good source of protein due to the high quality of its proteins, which means they are well absorbed by the body.
The protein content of normal milk is around 3.5 %. How can this be more than doubled? In yogurt, this is surprisingly easy to do: liquid is removed from part of the milk. Similar to quark and fresh cheese production, a liquid milk serum is produced as a by-product. If this is removed, the protein content increases.
Dried and filtered
Liquid removal is also important in Energy Milk and High Protein Milk, although it is not removed from the drinks themselves. Instead, milk protein that has undergone an additional drying process is added to them. Skimmed milk goes through a filtration process to remove the milk serum, increasing the protein content in the dry matter to more than 50 %. This milk protein is then dried and added to the drinks to increase their protein content.
High protein content in demand
It is important to consume enough protein, particularly before and after sports. The recommendation is around 0.8 g per kilogram per day, although older people and those doing a lot of sport may need up to 1.2 g – even more in some cases. Proteins not only provide the components for building muscle but are also important for regeneration. There are therefore a number of products with a high protein content, including Emmi High Energy Milk with 8 % protein and Emmi good day High Protein Milk with 7 % protein and only 0.1 % fat. The product with the highest protein content is YoQua yogurt, with 10 % protein.
Anyone who wants to consume even more protein can count on a traditional product of the dairy industry: cheese, which contains around 20 % protein. Removing liquid plays a role here too: ten kilograms of milk are needed to make one kilogram of cheese. Bon appétit!
