Inactivation of polyphenol oxidase using 254 nm ultraviolet light in a model system

2015-06-01

Abstract excerpt

Ultraviolet light (254 nm) induced inactivation of mushroom tyrosinase (polyphenol oxidase or PPO) was evaluated. Effect of typical fruit and vegetable juice components such as sugars (glucose, sucrose and fructose at 10 g/100 mL level), pH (3.5–6.8) and suspended particles (844 NTU) on UV induced PPO inactivation was also studied. PPO activity was measured spectroscopically using catechol as a substrate. UV proce...
