Ultrasound-Assisted Extraction Process of Polysaccharides from Okra Assisted By Response Surface Methodology

The extraction of polysaccharides from okra pods by ultrasound-assisted heating extraction was investigated using response surface methodology (RSM).The optimized conditions were ultrasonic temperature 63.19 , ultrasonic time of 10.04 ℃ min, liquid/solid ratio of 47.39: 1 (mL:g).The experimental optimized yield was 6.375%, which was well matched with the predicted value (6.435%).monosaccharidecomposition has been analyzed by Gas chromatography(GC).
