In this study, the effect of temperature and power intensity of ultrasound in the pectin extraction from passion fruit peel was evaluated. All the independent parameters presented significant effect on the extraction yield. The highest yield (12.67%) was ob- tained when the power intensity and temperature were 664 W/ cm2 and 85 C, respectively, however the GalA content and DE showed minimum values. Furthermore, the DE and GalA were affected by both variables tested. It was also observed that the extraction yield increased 1.6 fold when the extraction was assisted by ultrasound. The results obtained demonstrated that ultrasound was an efficient and time saving technique for extraction of pectin from passion fruit peel. A future studies concerning the energy efficiency of the processes have to be performed in order to compare the ultrasound and conventional techniques applied to pectin extraction.
