Abstract
The extraction conditions of polyphenols from the peel residue of pineapple by Ultrasound process were studied in this paper.The effects of seven factors including organic solvent and its concentration,extraction time,temperature,extraction times,the ratio of raw materials and solution and particle size of pineapple peel residue on extraction amount of polyphenols were investigated.The best technical conditions for polyphenols extraction were obtained through orthogonal experiments based on single factor as follows: 50% ethanol was used as a modifier,ratio of raw materials and solution was 1∶40,extraction time 20 min for per gram material and the yield is 7.98 mg/g.
