摘要: A lamb rennet paste preparation was studied to determine its suitability for the manu- facture of three main Spanish raw ewe's milk cheeses with Protected Designation Origin (Manchego, Idiazabal and Zamorano) from hygienic sensory points view. Cheeses were manufactured or commercial rennets (bovine powder Man- chego cheese liquid Zamorano cheeses) at identical levels coa- gulating strength. Free fatty acids partial glycerides also analysed study lipolysis relate them properties. No statistically significant differences detected in microbiological counts any species between non-paste rennet. We conclude that quality made this comparable showed a higher level than Sensory either type mainly cheese, whereas profile rather similar Manchego cheeses. highest scores odour flavour intensities, sharp odour, flavour, butyric pungent character. On other hand, had buttery attributes paste. / properties
