Description
Penicillium roqueforti molds naturally colonize cheese in limestone caves, creating characteristic blue veins without mechanical piercing.
Technical
The mold's extracellular enzymes (lipases like Roquefortine C and proteases) hydrolyze milk fats and proteins, producing methyl ketones (2-heptanone, 2-nonanone) and free fatty acids that create sharp, peppery flavors. The cave's natural ventilation (fleurs) provides optimal oxygen diffusion.
Culinary Significance
Produces the intense umami and piquant qualities of traditional Roquefort, with texture modification from casein breakdown.
