Special Issue Information

Dear Colleagues,

Currently, food losses represent a severe imbalance in the availability and accessibility dimensions of the short-term global food system. Therefore, food waste management plays a central role in this system since food waste is expected to rise to about 126 Mt by 2020, and the slogan “from waste to resources” is being promoted in order to inject food waste back into the economy as new raw materials, thus increasing the security of supply. Because up to 42% of food waste is produced by household activities and 39% by the food manufacturing industry, the circular economy is focused on the revalorization of those food losses (low-cost raw materials). These "secondary raw materials" can be traded and shipped just like primary raw materials from traditional extractive resources, thus accentuating certain properties (nutritional, functional, antimicrobial, etc.) through different recycling systems such as green extraction methods, which make this byproduct treatment economically attractive to the food industry and environmentally friendly promoting the sustainability. Hence, the main topic of this Special Issue is directed towards the application of various biotechnological techniques that manage to transform and improve the obtaining of bioactive compounds so they can be revalued and so their valuable properties can be used in food and even nutraceuticals and cosmeceuticals. Short communications, original articles, and reviews are welcome.

A large proportion of broccoli biomass is lost during primary production, distribution, processing, and consumption. This biomass is rich in polyphenols and glucosinolates and can be used for the production of bioactive rich ingredients for food and nutraceutical applications. This study evaluated thermosonication (TS) (18 kHz, 0.6 W/g, 40–60 °C, 3–7 min) for the pre-treatment of broccoli florets to enhance enzymatic conversion of glucoraphanin into the bioactive sulforaphane. TS significantly increased sulforaphane yield, despite a decrease in myrosinase activity with increasing treatment intensity. The highest sulforaphane yield of ~2.9 times that of untreated broccoli was observed for broccoli thermosonicated for 7 min at 60 °C, which was 15.8% higher than the corresponding yield for thermal processing without sonication (TP) at the same condition. This was accompanied by increase in the residual level of glucoraphanin (~1.8 and 2.3 time respectively after TP and TS at 60 °C for 7 min compared to control samples) indicating that treatment-induced release of bound glucoraphanin from the cell wall matrix and improved accessibility could be at least partially responsible for the enhanced sulforaphane yield. The result indicates the potential of TS for the conversion of broccoli biomass into high sulforaphane broccoli-based ingredients. Full article
