This article is about research on technological conditions for extraction of high active dietary fiber from Eucheuma. The optimum technological conditions for alkali treatment and bleaching of Eucheuma have been chosen by orthogonal design method.The high active dietary fiber have been produced from Eucheuma by the optimum conditions.The functional property of Eucheuma dietary fibers was tested by human body taking orally.The results showed that the yield of high active dietary fiber of Eucheuma was 32.41%,and the color was nearly white.The contents of dietary fiber,calcium and phosphorus were 82.57%,2.13% and 0.013% respectively.The expansive capacity and water holding capacity were 24.5 mL/g and 1450% respectively.The functional property of Eucheuma dietary fiber was better than wheat bran fiber,and Eucheuma dietary fibers had a good curative effect for constopation patient.
