| Abstract: | Polyphenols was extracted from pineapple peels by ethanol reflux method.The antioxidant level was determined by the color reaction of ferrous tartrate with the polyphenol extract.The best extraction conditions were obtained by orthogonal experiments.The results showed that the optimum extraction conditions were obtained with ethanol concentration of 70%,extraction temperature of 50 ℃,the ratio of material to liquid of 1∶8(g∶mL)and extraction time of 45 min.The amount of Polyphenols extracted from Pineapple Peel was12.65mg/g. |
