Citrus fruit peels are used as the primary source for pectin production, effectively
transforming fruit waste into a valuable resource and making a significant contribution to
fostering a circular economy. This study aimed to extract pectin from locally available citrus
fruits such as Elephant Apple, inner peel (IP), and outer peel (OP) of Pomelo. Pectin was
extracted using acid hydrolysis and sodium-hexa-meta-phosphate extraction, and its
physiochemical properties, including moisture, ash, methoxyl content, equivalent weight …
