Influence of ripening on proteolysis and lipolysis of Murcia al Vino cheese

Abstract

The aim of this study was to evaluate the influence of five different manufacturers and two ripening periods on the proteolysis and lipolysis patterns of Murcia al Vino goat cheese. The manufacturers significantly affected the water activity ( a w ), pH , dry matter and fat content, several nitrogen fractions: water soluble nitrogen (WSN), trichloroacetic acid (12% w/v) soluble nitrogen (TCASN) and phosphotungstic acid (5% w/v) soluble nitrogen (PTASN); also the free amino acid (FAA) and free fatty acid (FFA) contents, with the exception of C 4:0 , C 16:0 and C 18:0 . Different ripening periods significantly affected the dry matter content, WSN and PTASN and all FAA, except serine.
