Description
Protease enzymes accelerate cheese aging by selectively cleaving milk proteins to mimic prolonged maturation.
Technical
Microbial proteases (e.g., from Aspergillus oryzae) hydrolyze casein into peptides and free amino acids, bypassing slow natural proteolysis. This triggers Maillard reactions and volatile compound formation characteristic of aged cheeses.
Culinary Significance
Enables rapid production of sharp-flavored cheeses while reducing storage costs, though may lack depth of traditional aging.
