In this study, pectin was extracted by acid extraction method from pomegranate peel. The temperature, time and particle size which affected pectin yield were optimized using response surface method. As a result of optimization, optimum conditions for pectin extraction from pomegranate peel were determined as 468-568 µm for particle size, 82°C for temperature and 47,5 minutes for extraction time. After the extraction at optimum conditions pectin yield was found to be 25,96%. In addition, pectin that was produced had equivalent weight of 488,01 mg, methoxyl content of 5,74%, the degree of esterification of 47,43%and anhydrogalacturonic acid content of 68,64%. The results showed that the obtained pectin was low methoxyl pectin.
