Tejsavófehérje

Tejsavófehérje, commonly known as whey protein in English, is a complete protein derived from milk. It is one of the two primary proteins found in milk, the other being casein. Whey protein is extracted during the cheesemaking process as a byproduct when milk is curdled and strained. It is valued for its high biological value, meaning it is easily digested and absorbed by the body and contains all nine essential amino acids that cannot be synthesized by the body.

Whey protein exists in several forms, including whey concentrate, whey isolate, and whey hydrolysate, each differing in its protein content and processing. Whey concentrate typically contains around 70-80% protein, with some lactose and fat remaining. Whey isolate undergoes further processing to remove most of the fat and lactose, resulting in a higher protein concentration, often exceeding 90%. Whey hydrolysate is pre-digested, meaning the protein chains are broken down into smaller peptides, which allows for even faster absorption.

Due to its nutritional profile and rapid absorption, whey protein is frequently used as a dietary supplement. It is popular among athletes and fitness enthusiasts for its role in muscle repair and growth following exercise. It is also incorporated into various food products, including protein bars, shakes, and infant formulas. Research has also explored its potential benefits in areas such as weight management and immune support, though more extensive studies are ongoing.
