Passion fruit is one popular fruits in Brazil, and its annual production represents 70 % of the world production. About 60 % of fruit is mesocarp and epicarp (peel) and contains high levels of pectin that can be extracted using heating or alternative technologies. The purpose of the present work was to investigate the potential of high pressure to extract the pectin from passion fruit peel. The results showed that the extraction yield almost doubled (from 7.4 to 14.34 %) when high pressure was used as a pretreatment. The esterification degree and galacturonic acid of the pectin extracted were higher by 50 and 65 %, respectively. High pressure as a pretreatment was found to be an effective, time-saving, and eco-friendly method for the extraction of pectin from passion fruit peel.
