No, mozzarella is not plastic. While the process of making mozzarella, especially the pasta filata type, involves stretching and manipulating the curd in hot water, giving it unique "plastic" properties in terms of malleability, it's still a natural cheese made from milk.
Here's a breakdown:
-
What gives mozzarella its stretchy texture? The texture comes from the way the cheese is made.
- The curd is coagulated and then immersed in hot water.
- It's then stretched and kneaded (like pasta), which aligns the protein structures. This process is called pasta filata.
- This alignment is what allows the cheese to melt and stretch so well. The pH level (around 5.2, as noted in the reference) is crucial for this.
-
Plastic vs. Plasticity: It's important to distinguish between the material "plastic" (a synthetic polymer) and the physical property of "plasticity" (the ability of a material to deform without breaking). Mozzarella exhibits plasticity during its manufacture and when melted.
-
Mozzarella's Composition: Mozzarella is made from milk, rennet (or another coagulant), and citric acid (or another acidulant). It's a natural food product.
-
Summary: The "plasticization" referenced describes the process of making the cheese pliable, but mozzarella is not made of plastic. It is a dairy product whose proteins are altered for texture.
