Beta-lactoglobulin (BLG) is the most common protein in cow's milk serum, accounting for 50% of the total protein in the whey fraction. This protein has no homologous counterpart in human milk, making it an important marker for diagnosing allergic reactions to milk.
BLG is a major allergenic component of cow's milk and plays a key role in the development of allergic reactions in children and adults. Although modern infant formulas try to mimic human milk, BLG remains the dominant protein in the formula, which can trigger allergies in sensitive children. Measuring BLG levels helps assess sensitization risk, monitor treatment, and adjust diet to reduce allergic symptoms.
