Food Science and Technology QUESTION #5896
Question 1
Mozzarella cheese is a pasta filata (stretched curd) cheese. The stretching step requires curd to be heated to approximately:
  • \(25^{\circ}\text{C}\)
  • \(45^{\circ}\text{C}\)
  • \(55\text{–}65^{\circ}\text{C}\)✔️
  • \(80^{\circ}\text{C}\)
Correct Answer Explanation
Pasta filata curd must be heated to \(55\text{–}65^{\circ}\text{C}\) (in hot water \(\approx 75\text{–}80^{\circ}\text{C}\) or hot whey). At this temperature casein fibers become thermoplastic and align upon stretching, creating the characteristic fibrous elastic structure.
