Cheese Production: The Biochemistry of Matrix Transformation

Cheese production is a rigorous exercise in biochemical engineering, transforming a colloidal suspension into a stable viscoelastic gel.

1. Coagulation: Destabilizing the Micelle

Milk's stability relies on the electrostatic repulsion of **Casein Micelles**. Coagulation is achieved via:

* **Enzymatic**: Chymosin targets the $\kappa$-casein bond.

* **Acid**: Lowering pH to the isoelectric point ($\approx 4.6$).

2. Fermentation: The Metabolic Engine

Cheesemaking is the controlled fermentation of lactose into lactic acid by **Lactic Acid Bacteria (LAB)**.

3. Precision Fermentation (PF)

The frontier of the field is producing recombinant casein and whey analogues using genetically engineered microorganisms.
