A critical analysis of the cold plasma induced lipid oxidation in foods
2018
Abstract Background Cold plasma is an emerging, economical and environment-friendly technology with potential applications in food and bioprocessing industry, including microbial decontamination, enzyme inactivation, shelf-life extension, and physicochemical modification. These advantages stem from the cocktail of reactive species and the physical processes that are associated with gaseous electrical discharges. However, when oxygen is present as a component of the gas in which plasma discharges are made, the reactive oxygen species (ROS) could result in decreased food quality. The lipids oxidation induced by an oxygen-containing cold plasma process can eventually affect the acceptability a…
Emerging macroscopic pretreatment
2021
Macroscopic pretreatment of food waste aims at the preparation of the food matrix for subsequent processing and recovery steps. The preparatory steps involve the adjustment of the phase content and properties (water, solid, fats content), the moderation of enzyme activity as well as prevention and control of any microbial growth (Galanakis, 2012; Galanakis et al., 2010a). In recent times, several emerging technologies have been researched, developed, and/or adapted from other fields for drying, sterilization, enzyme inactivation, and enhancing mass transfer in food and biomaterials. This chapter focuses on these upcoming technologies with potential applications to food waste recovery and in…
