Casar cheese studied in the present work is made from ewe raw milk coagulated with an aqueous extract of Cynara
cardunculus L. (cardoon) flowers.
The strong activity of cardoon enzymes, the raw milk microbiota and the high cheese pH values may cause over-ripening during refrigerated storage of ripe cheese.
In a previous work (Calzada et al.2013), we achieved a delay in proteolysis during refrigerated storage of Casar cheese by means of HPP treatments on days 21 and 35 after manufacture, at 400 or 600 MPa.
In the present work, we have investigated the influence of HPP treatments under the same conditions on the lipolysis, the formation of volatile compounds and the appearance of off-odours throughout ripening and refrigerated storage of Casar cheese
