Title: Optimization of extraction for pectin compounds from orange peel with ultrasonics by response surface method
Abstract: The pectin was extracted from orange peel with hydrochloric acid and ultrasonic,and precipitated with ethanol.The influences of the pH value,the ratio of solid and liquid,the ultrasonic time,the ultrasonic frequency and the ultrasonic temperature on the extraction efficiency were investigated.The L16(45)orthiogonal experiment and response surface method result showed that the optimum reaction condition was:pH value 1.0,ultrasonic frequency 20.7 kHz,extraction temperature 73℃.The best extraction content of pectin was 18.2%.
