Production of Sensorily Acceptable Pasta Filata Cheese with Partial Substitution of Sheep’s Milk Powder in Different Forms

Abstract

The presented study analyzed the possibility of pasta filata cheese production using sheep’s milk powder in different forms and substitution amounts with fresh cow’s milk. For the production of the pasta filata cheeses that were analyzed in the research, sheep’s milk powder and reconstituted sheep’s milk were used for partial substitution with fresh cow’s milk in the amount of approx. 20, 30 and 40 percent (v/v). The obtained results showed that the more sheep’s milk in the form of powder in the mixture, the lower the cheese’s moisture content. The fat and protein content in the whey after the production of cheeses from mixtures was lower than after the production of cheeses from reconstituted sheep’s milk only. Cheeses produced entirely from reconstituted sheep’s milk displayed the highest fat loss. The greatest cheese yield was observed for cheeses from mixtures with sheep’s milk powder and entirely from reconstituted sheep’s milk. Pasta filata cheeses made from a mixture of cow’s milk and sheep’s milk powder that was not reconstituted were much less acceptable to consumers than reconstituted milk powder cheeses, especially those with 40% and 30% added powder. Sensory profile analysis showed that the addition of sheep’s milk to the mixture, regardless of the form, affected the appearance, consistency, and flavor of the produced pasta filata cheeses. Mixing cow’s milk with sheep’s milk powder created the possibility of modeling the final cheese quality and yield.

“…The cheese was produced using fresh, raw cow's (CS) milk and sheep's milk powder after reconstitution (SR) in a ratio of 70:30 (CS:SR). A detailed description of the milk used for the production of the cheese was described by Biegalski and Cais-Sokoli ńska [21]. The procedure of making pasta filata cheese was described by Biegalski et al [22].…”
