THE INFLUENCE OF ULTRAFILTRATION OF EWE´S MILK ON SOFT CHEESES PROPERTIES

ABSTRACT



Ewe's milk non-concentrated and concentrated by ultrafiltration to 60% of initial volume, was processed into soft cheese. The cheese were stored, in 4°C, for 14 days. The milk, retentate and fresh cheese were analyzed and also cheese after 7 and 14 days of storage were estimated. Organoleptic assessment, yield, physico-chemical properties and texture analyses were done in cheese. It was observed that cheese yield made from ultrafiltrated milk was higher than from non-concentrated milk. The fresh cheese made from concentrated milk contained more: water, total nitrogen compounds and free fatty acids and less fat. These cheese were softer and had higher cohesiveness than cheese made form non-concentrated milk. The ultrafiltration enchanced the cheese properties. All cheese were edible after 14 days of storage.

Key words: ewe´s milk, ultrafiltration, retentate, fresh cheese, physico-chemical properties, texture.
