Cocoa liquor, butter, and powder represent derived products from a small portion of the fruits, compared with the cocoa pod husk (CPH) which accounts for ~70 % of fresh weight. CPH, improperly disposed in plantations, can cause diseases threatening worldwide chocolate production. However, this biomass can be a potential source of bioactive compounds aligned with the circular economy. An overview on the different methods for extracting pectin, resulting in variable extraction yields with a critical discussion on the obtained physicochemical characteristics, is presented. Additionally, the potential applications of the extracted pectin for food and biomedical application are discussed, including thickener, stabilizer, excipient, drug-release modifier, macrophage activator, etc. Despite these potential outputs, new extraction methods need to be considered for improving efficiency and sustainability. Finally, potential approaches are introduced that can help to minimize the environmental impact, making the extraction cost-and time-efficient, and, therefore, more ssustainable for a further successful translation to industry.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
