Integrated Biorefinery Strategy for Valorization of Pineapple Processing Waste into High-Value Products

The present study aims to recover value-added products from fresh pineapple processing wastes in an integrated biorefinery. Bromelain, a therapeutic protease, was extracted from pineapple by-products via an aqueous, low-temperature process. Bromelain-free biomass was rich in insoluble fibre and was further fractionated into hemicellulose, cellulose and lignin. The highest content of active bromelain was obtained from pineapple core waste of the...
