Abstract

Non-starch polysaccharides recovery from overripe bananas is challenging due to the high quantities of soluble sugars accumulated during the ripening process. Non-starch polysaccharides isolated from overripe bananas may be used as a functional ingredient. Kinetic extraction of soluble sugars from ripe banana (Musa cavendishii) using ethanol as solvent is presented. Different extraction methods (mechanical stirring and ultrasound-assisted), solid/solvent ratio (1:3 and 1:5) gmL(-1) and temperature (25 and 65) degrees C were investigated. Process efficiency was evaluated through the extraction index (EI), defined as the percentage of sugar extracted after 30 min. Soluble solid extraction curves were adequately represented by Patricelli and Peleg models, but only the Patricelli model represented the water extraction adequately. The condition that maximizes the soluble solids extraction and minimizes energy consumption was 1:5 g.mL(-1) of solid/solvent ratio, 25 degrees C under mechanical stirring (EI = 87 +/- 1 g(ss) (extract)/100 g(ss) (banana)).
