Abstract

Food waste, accounting for about one-third of the total global food resources wasted each year, is a substantial challenge to global sustainability, contributing to adverse environmental impacts. The utilization of food waste as a valuable source for bioactive extraction can be facilitated through the application of DES (Deep Eutectic Solvents). Acknowledging the significant need to tackle this issue, the United Nations integrated food waste management into its Sustainable Development Goals, hence, the present review explores the role of DES in bioactive compounds extraction from food waste. Various extraction processes using the DES system are thoroughly studied and the application of bioactive components as antioxidants, antimicrobials, flavourings, nutraceuticals, functional ingredients, additives, and preservatives is investigated. Most importantly, regulatory considerations and safety aspects of DES in food applications are discussed in-depth along with consumer perception and acceptance of DES in the food sector. The key hypothesis of the review is to evaluate emerging DES systems for their efficiency in bioactive extraction technologies and various food applications. Overall, this review provides a comprehensive understanding of utilizing DES for synthesizing valuable food waste-derived bioactive components, offering a sustainable approach to waste management and the development of high-value products.
