The extraction of pectin from the ripe Okra using Al2(SO4)3 as precipitation were studied. The orthogonal matrixexperiments showed that the best pH value in acidic extraction stage, extraction temperature and the extraction time were 4, 60 ℃ and 90min, respectively, under which the extraction rate of pectin from Okra was be up to 25.96%. This research confirmed that Okra is an excellent source of pectin.
