Title: Total Phenolic Content and Antioxidant Activity of Local Fruit Wastes in Malaysia
Abstract: The purpose of this study is to investigate the antioxidant properties and total phenolic content in local fruit wastes. Watermelon rinds, mango and banana peels were selected in the experiment. Two parameters involved were the extraction time and temperature. All samples had undergone drying process in an oven at 40°C for 24 hours before being extracted with 80%, v/v methanol on a hot plate together with magnetic stirrer. The extraction time was ranged from 20 to 40 minutes and the extraction temperature was from 30 to 60°C. Ferric Reducing Antioxidant Power (FRAP) assay and Folin-Ciocalteu reagent were used for antioxidant analysis and phenolic content determination, respectively. UV-Vis spectrophotometer was used to detect the antioxidant activity at 593 nm and 765 nm for phenolic content. Response Surface Method was used to find the best extraction condition. The best extraction conditions were found at extraction temperature and time of 58.93°C and 37.86 minutes, respectively.
