General Stability

EC Number General Stability Organism
3.2.1.15 PG1 and PG2 are stable up to 300 MPa for 15 min at 25°C, nearly complete inactivation at 500 MPa. Thermal and high-pressure inactivation kinetics of purified PG2 at pH 4.4. High pressure processing is an alternative to inactivate the enzyme without the need for applying high temperatures Solanum lycopersicum
