Abstract:
Milk protein represents an important source of amino acids and peptides in the human diet. In recent years, whey has gained immense recognition as a protein source in functional foods, infant formulas, and bakery products.

The objectives of this study were to investigate some functional properties of whey protein hydrolysates obtained with chymotrypsin as a function of pH and thermal treatment. The extent of hydrolysis and conformational changes induced by pH and temperature were monitored using intrinsic fluorescence intensity and anisotropy.
