SYNTHESIS AND CHARACTERIZATION OF pH SENSITIVE HYDROGEL USING EXTRACTED PECTIN FROM DRAGON FRUIT PEEL

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… (More)
