How milk type, coagulant, salting procedure and ripening time affect the profil...
Freitas, A. C.; Fresno, J. María; Prieto, Bernardo; Franco, Imaculada; Malcata, F. Xavier; Carballo, JavierThe concentration of total free amino acids (FAA) in Picante cheese increased with ripening time irrespective of the particular protocol used for manufacture (ie ratio of caprine to ovine milks, animal or plant rennet and number of salting steps). The experimental cheeses manufactured with 20% (v/v) caprine milk, coagulated with animal rennet and salted only once exhibited the highest content of total FAA by 12...
Influence of milk source and ripening time on free amino acid profile of Picant...
Freitas, A. Cristina; Fresno, J. María; Prieto, Bernardo; Franco, Inmaculada; Malcata, F. Xavier; Carballo, JavierThe evolution of concentration of free amino acids in Picante cheese throughout ripening was studied for several volumetric ratios of ewe's and goat's milks. The concentrations of all free amino acids, except asparagine, γ-aminobutyric acid, and cysteine, generally increased as ripening time elapsed. Analyses of variance have indicated that ripening time and, to a lesser extent, milk composition have significan...
Effects of ripening time and combination of ovine and caprine milks on proteoly...
Freitas, A. Cristina; Fresno, J. Maria; Prieto, Bernardo; Malcata, F. Xavier; Carballo, JavierProteolysis in Picante cheese was characterized by assaying for breakdown products throughout a 180 day ripening period using different combinations of ewe's and goat's milks. Parameters analysed were total nitrogen (TN), water-soluble nitrogen (WSN) and non-protein nitrogen (NPN) using Kjeldahl and spectro-photometric methods, and casein profile by electrophoresis. WSN at 180 days of ripening was 25–29% TN. Th...
