The goal of this study is to use a simple approach to synthesize pectin from grapefruit peel, an agricultural waste common in tropical regions. Additionally, the study employed optimization techniques to identify the ideal conditions for the maximum extraction efficiency while also determining the importance of studying factors. Besides, extracted pectin characteristics are also presented in this research. Under several analysis, some chemical groups for pectin were presented in extracted pectin by Fourier transform infrared spectroscopy analysis (FTIR). For instance, C-H methyl groups at the peak 1442 cm^-1; methyl ester groups C=O appears at the wavelength 1747 cm^-1 and aliphatic C-H groups and hydroxyl groups. Furthermore, under three major conditions acid (%); temperature and time extraction, an optimization study was conducted to figure out the optimal conditions for pectin extraction efficiency. Under optimal conditions acid 10%; 77.5 °C and 80 mins is the favorable condition for obtaining pectin extraction efficiency. Basically, this study is the first one extracting pectin from rosy-pulp pomelo peel by sulfuric acid-ethanol precipitation method. This is a preliminary that lays the foundation for purifying extracted pectin from rosy-pulp pomelo, also solving this agricultural waste bring higher economic values.
