What You Need to Know
During ripening, casein‑specific enzymes such as chymosin, plasmin, and bacterial proteases cleave casein into peptides and free amino acids, which then undergo further transformations to form flavor compounds. Lipases from starter cultures and ambient molds hydrolyze triglycerides into short‑chain fatty acids (e.g., butyric, caproic) that contribute to sharpness and buttery notes. Moisture loss concentrates proteins and salts, lowering water activity and enhancing texture and flavor intensity.
