Abstract
Glucose oxidase (GOD) produced by a strain of Penicillium (Penicillium
variabile P16) was employed, in a model system, to control the activi
ties of tomato lipoxygenase (LPO), polyphenoloxidase (PPO), and peroxi
dase (POD). GOD inhibited all three enzymes, at the typical pH of toma
to fruit (4.3), i.e., the LPO was inhibited up to ca. 88%, the PPO up
to ca. 63% and the POD rtp to ca. 50%. GOD also prevented p-carotene b
leaching caused by these enzymes.
