Abstract (EN): The breakdown of ¿s-caseins and ß-caseins (in the form of ¿s-caseins, the form of ß-caseins, and the form of a mixture of ¿s- and ß-caseins in Na-caseinate) by cardosin A, one of the major two proteinases present in the flowers of Cynara cardunculus L., was experimentally studied via urea polyacrylamide gel electrophoresis. In Na-caseinate, ¿s- and ß-caseins were degraded up to 46 and 76 %, respectively, by 10 h of hydrolysis. In separated form, ¿s-caseins reached a level of degradation up to 67 % while ß-caseins were quickly and extensively degraded up to 76 %. In general, ß-caseins seemed to be more susceptible to proteolysis than ¿s-caseins. © Inra/Elsevier, Paris.
