الملخص EN

The aim of this study was to extract and evaluate the functional properties of the Total dietary fibers (TDF) from three varieties of Date palm (Phoenix dactylifera L.), namely, Zahdi, Ashrasi and Ibrahimi.

Pomace was obtained as by product of treacle or dibs production.

Total Dietary fibers (TDF) were extracted by Enzymatic method and Soluble Dietary Fibers, SDF and Insoluble Dietary Fibers, IDF were extracted too.

Extracted Dietary fibers were investigated for yield extraction and Bulk density (BD), Water holding capacity (WHC), Oil holding capacity (OHC), Cholesterol Adsorption Capacity (CAC) and Emulsifying Properties (EP) and compared with those of commercial cellulose (CC).

The results show that: The quantity of TDF extracted from Zahdi, Ashrasi and Ibrahimi pomace were 75.28, 84.41 and 72.23 g / 100 g, respectively.

Bulk density of TDF were 0.298, 0.271 and 0.335 g/ml extracted for Zahdi, Ashrasi and Ibrahimi pomace, respectively, comparing with 0.5 g / ml for CC.
