Abstract: The experiment studied about the effect of chemical method and enzymic method on the physicochemical properties of dietary fiber from Passionflora edulis seed, including swelling capacity, water-holding capacity, water-bonding capacity, fat-bonding capacity, cholesterol sorption capacity and sodium cholate sorption capacity. Then the yield, appearance and physiochemical properties were compared between them. Results showed that the dietary fiber prepared by enzymic treatment had a pure yield of 60. 31%, higher purity and homogeneous particle diameter, being superior in water-holding capacity, saturated fat-bonding capacity, and sodium cholate sorption capacity. But the dietary fiber prepared by chemical treatment, which dominated in swelling capacity, water-bonding capacity and unsaturated fat-bonding capacity, had a pure extraction rate of 50. 21%.
