Abstract: The technological conditions of alkali treatment and chemical modification for extraction of high active dietary fiber (DF) from Eucheuma striatam were studied in the paper by orthogonal design method. The results showed that yields of Eucheuma striatam DF is 49.0%. The contents on dry basis of DF, calcium, expansion capacity and water holding capacity are 85.3%, 1.21%, 29.5ml/g and 17.5g/g respectively for Eucheuma striatam DF extracted under the optimum conditions.

Key words: Eucheuma striatam, dietary fiber, extraction
