Abstract

The aim of this study is to synthesis pectin-based hydrogel from the dragon fruit peel. The pectin was extracted using acid extraction (pH 3.5) that carried out at 60 °C for 30 minutes. The extracted compound conformation was analyzed by calculating the degree of esterification (DE) and the analysis was confirmed by the FTIR analysis spectrum. The dragon fruit peel pectin (PcDF) and acrylic acid (AA) hydrogel (AA-PcDF) was fabricated using a free radical polymerization in aqueous solution. Its uptaking efficiency was determined in different pH buffer solutions and their swelling percentage was calculated. Futher characterizations were made by using FTIR and SEM to examine the AA-PcDF hydrogel physicochemical properties. Results obtained showed that this new material has a high potential to be used as biomaterial in pharmaceutical and medical purposes.
