What You Need to Know
Mechanical piercing (5-20mm diameter) introduces oxygen channels that regulate Penicillium roqueforti growth while allowing localized casein hydrolysis by plasmin enzymes (EC 3.4.21.7).
Creates pockets of intensified umami through concentrated glutamic acid formation near tunnel walls.
