High pressure treatments (100-500 Mpa/4 °C/10 min) were carried out on freshly sliced mushrooms ( Agaricus bisporus ) and on liquid extract. Pressure above 200 MPa led to respiratory activity loss, significant enzymatic browning and polyphenoloxidase (PPO) activation in treated mushrooms. Increasing pressure from 200 to 500 MPa enhanced the PPO activation (in whole tissue and in liquid extract). Stabilization of mushroom by high-pressure (HP) alone cannot be considered. A combination of HP with thermal or chemical treatments is found necessary.Read less <
