Abstract:The article conducts research on the, concerning utrasonic-assisted pectin extraction from passionflower peel, examining the impact of the power and the lasting time of ultrasonic, viscosity, extraction temperature and pH value to the extraction, arranging orthogonal test through L16(45 ). The results show the best condition for pectin extraction: ultrasonic power: 200 W, ultrasonic lasting time: 35 min, mix ratio: 1:19 (g:mL), extraction temperature: 40 Celsius, PH value: 1.8. Compared with the traditional acid method, extraction ratio has grown from 2.22% to 2.51% and extraction time has reduced from 3.5 h to 35 min.
Keywords:ultrasonic  pectin  passionflower peel  extraction
