Valorization of Pineapple Waste: a Review on How the Fruit's Potential Can Reduce Residue Generation

Pineapple is a fruit of unique appearance and flavor, consumed in natura or processed to obtain different products. However, the processing step generates a series of residues such as crown, stem, cylinder, leaves, and pomace, which have been widely studied due to the high amount of bioactive compounds, dietary fibers, and commercial enzymes found. Different government institutions already established laws detailing treatments required for fruits, like pineapple, and other food waste, either for reuse or disposal. Public policies and waste reuse are necessary to achieve sustainable development, expanding the possibilities for discovering new products and compounds. The current review analyzed different propositions from the literature on the application and valorization of pineapple waste, besides presenting industrial applications for these residues and legislative aspects related to residue treatment policies of different governmental institutions.
