What You Need to Know
Milk proteins (caseins) are enzymatically cleaved by rennet, causing micelle aggregation and curd formation while lactic acid bacteria lower pH and promote casein destabilization. Heat treatment above 80 °C denatures whey proteins, influencing moisture retention, and subsequent proteolysis and lipolysis during ripening generate peptides, free amino acids, and fatty acids that define flavor. Salt addition modulates water activity and microbial activity, while controlled temperature and humidity during aging drive enzymatic and microbial reactions that mature the cheese matrix.
Steps
- 1.
Fondue Savoyarde (Swiss Alps): Aged Gruyère and Emmental provide melting properties and flavor depth
- 2.
Pasta alla Carbonara (Lazio, Italy): Pecorino Romano's salty crystallinity creates sauce texture
- 3.
Queso Fundido (Northern Mexico): Asadero cheese's stretchability comes from specific pH development
