Compositional characteristics of Murcia al Vino goat's cheese made with calf rennet and plant coagulant

Abstract

The aims of the present study were to determine compositional characteristics of Murcia al Vino goat's cheese and to evaluate the effect of different types of coagulants (animal rennet and powdered vegetable coagulant obtained from the cardoon Cynara cardunculus) on the improvement of the technological quality of Murcia al Vino goat's cheese. Only the pH, TA and ash and Ca contents were affected in a significant way by the type of coagulant used. There was a decrease in the moisture and an increase in the sodium chloride during ripening, while other parameters were unchanged. The pH and titratable acidity (TA) values of the cheeses were affected significantly by the time of ripening. There was an increase of the Na as well as a significant decrease of the Ca, P, Zn, Cu and Fe components, as a consequence of the increase of the acidity of the cheese during ripening. The esterified fatty acids were not modified significantly by the type of coagulant or by the time of ripening. Those most abundant in this type of cheese were C16 and the C18: 1. © 2008 Society of Dairy Technology.
