The residual activity of many enzymes is detrimental to the
quality of foods, resulting in effects such as browning, off-flavour and loss of vitamins.
In certain cases, validation of processing conditions can only be achieved when the critical parameters of plasma processes assure inactivation of not only micro-organisms but also enzymes (Mastwijk & Groot, 2010). Through this review we provide a firm foundation for future investigation of cold plasma effects on food enzymes and the associated consequences
on food quality. We discuss the concerned literature highlighting the effects of cold plasma on enzyme activity in various model and real food systems, the kinetics of inactivation, and the future research needs.
