Why Does Cottage Cheese Have So Much Protein?
Cottage cheese has been a staple in many cuisines for centuries, and its high protein content is one of its most notable characteristics. In this article, we will explore the reasons behind cottage cheese’s impressive protein profile, and examine the nutritional benefits of incorporating it into your diet.
Why does cottage cheese have so much protein?
Cottage cheese is made from the whey of milk, which is a byproduct of cheese production. The whey is rich in milk proteins, including casein and whey protein, which are responsible for its high protein content. The unique combination of these proteins and the way they are processed are the main reasons why cottage cheese has so much protein.
The Whey of Milk
Milk contains two main types of proteins: casein and whey protein. Casein makes up about 80% of milk protein, while whey protein makes up the remaining 20%. Whey protein is the liquid part of milk that separates from the curds during cheese production, and it is this liquid that is used to make cottage cheese.
Microfiltration and Protein Preservation
During the production process, the whey is microfiltered to remove the fat and lactose from the liquid. This leaves behind a concentrated liquid with a high protein content, which is then acidified to create the curds. The acidification process helps to preserve the whey protein, allowing it to retain its bioavailability and nutritional value.
The Role of Bacterial Fermentation
Another crucial step in the production process is bacterial fermentation. Bacteria such as Lactococcus lactis subsp. lactis and Lactococcus lactis subsp. cremoris are added to the whey to convert the lactose into lactic acid. This fermentation process not only helps to acidify the whey, but also breaks down some of the casein, releasing more whey protein and increasing the overall protein content of the final product.
