87. Effect of Milk Source on Quality of Mozzarella Cheese (2006)<br />

Hamid Mohand Kaci\ Jordan University of Science & Technology<br />

Supervisor: Dr. Reyad Shaker<br />

Mozzarella cheese belongs to the pasta filata or pulled curd category, which<br />

includes other types of cheese like Provplone and Scarmoza. It is a mild white cheese<br />

with a semi-soft and elastic texture. Mozzarella is best used for cooking and is popular<br />

for pizza because of its excellent melting qualities.<br />

The objective of this study was to compare among the compositions and<br />

functional properties of Mozzarella cheese made from unstandardized bovine, ovine<br />

and caprine milks. In addition, standardization of milk at 3% fat content and mixing<br />

equal portions of milks were also investigated. Cheeses were stored at 4 °C and<br />

evaluated at 1, 8, 15, 22, 29, 36, 43, 50 and 56 days of age.<br />

Meltability and stretchability were significantly lower in mozzarella cheese made<br />

from unstandardized caprine milk, compared with unstandardized bovine and ovine<br />

mozzarella. Moreover, mozzarella made from unstandardized bovine and ovine milks<br />

formed a significantly higher amount of free oil throughout storage. The results<br />

indicated that bovine and ovine mozzarella cheeses underwent a greater structural<br />

degradation of casein matrix, than that of caprine cheese during ripening.<br />

Pizza topped with unstandardized caprine mozzarella cheese showed significantly<br />

lower browning than pizza topped with bovine and ovine cheeses, whereas<br />

pizza topped with bovine mozzarella cheese led to more intense brown color than<br />

pizza of ovine cheese. Meltability, stretchability and free oil were significantly higher<br />

in mozzarella made from standardized bovine and ovine milks compared with<br />

mozzarella made from standardized caprine milk. Pizza made from bovine and ovine<br />

mozzarella showed a significantly higher browning potential than caprine cheese.<br />

The results showed no significant differences between mozzarella cheeses made<br />

from mixing equal portions of bovine/ovine and bovine milks. Meltability of<br />

mozzarella made from bovine/caprine and ovine/caprine milks was lower than that of<br />

bovine mozzarella cheese.<br />

Stretchability was significantly lower in mozzarella made from bovine/caprine<br />

and ovine/caprine compared with mozzarella cheese made from bovine milk. In<br />

addition, no significant difference was found in stretchability between mozzarella<br />

cheeses made from bovine/ovine and bovine milks. Free oil was slightly lower in<br />

mozzarella made from bovine/caprine and ovine/caprine milks compared with<br />

mozzarella cheese made from bovine milk, whereas no significant difference was<br />

found between mozzarella cheeses made from bovine/ovine and bovine milks.<br />

Browning was significantly higher in pizza made from bovine/ovine and bovine<br />

mozzarella cheeses compared with mozzarella cheese made from bovine/caprine and<br />

ovine/caprine milks.<br />
