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.
