Goat cheeses were made from pasteurized (72 degrees C, 15 s) and high-press
ure (HP)-treated milk (500 MPa, 15 min, 20 degrees C). At 45 days of ripeni
ng, cheeses made from both types of milk were similar in moisture, quality,
electrophoretic profiles, water-soluble nitrogen, and total free fatty aci
d contents. Cheeses made from HP-treated milk had higher pH and salt, matur
ed more quickly, as determined by formation of total free amino acids, and
developed strong flavors. Reverse-phase high-performance liquid chromatogra
phy showed differences between the peptide profiles of the cheeses. Differe
nces in small peptides and free amino acids indicated a higher extent of pr
oteolysis in cheeses made from HP-treated milk.
