Zusammenfassung
Es wurde der Wechsel in der Zusammensetzung der Textur, der Stickstofffraktionen, der Fettbestandteile und eine Caseinhydrolyse des „Cabrales”-Käses während viermonatiger Reifelagerung studiert. Zusätzlich gibt es auch eine starke Lipolyse. Ungefähr 88% des gesamten Stickstoffs und fast 79% des löslichen Stickstoffs waren Nicht-Protein-Stickstoff. Der Abbau des αs-casein undß-casein war am Ende der Reifung vollständig und in dieser Zeit war der Gehalt an freien Fettsäuren 33 153 mg/kg. Der Korrelationskoeffizient wurde für alle Variable bestimmt und die Diskriminationsanalyse wurde angewandt, um alle Cabrales-Käse entsprechend der Reifungszeit zu klassifizieren.
Summary
Changes in the global composition, textural parameters, nitrogen fractions, fats characteristics and casein breakdown in Cabrales cheese were studied over a maturation period of four months. Extensive proteolysis and lipolysis occurred. Approximately 88 % of the total nitrogen in the mature cheese was water-soluble and nearly 79% of the water-soluble nitrogen was non-protein nitrogen. Degradation of αs- andß-caseins was complete at the end of ripening, and at this stage the total free fatty acid (FFA) content was 33 153 mg/kg. Correlation coefficients were calculated for all variables and stepwise discriminant analysis was applied in order to classify Cabrales cheeses according to ripening time.
