The current study is aimed at fortifying Barbari bread with different levels (

The fiber of the defatted olive pomace powder was extracted by an enzymatic process as a green extraction method (α-amylase, protease, amyloglucosidase, and cellulase; incubation time: 4.5 h, 40°C). The effect of ODF addition on the thermal (based on differential scanning calorimetry (DSC)), rheological, physical, textural, and sensory properties of samples was investigated. The DSC curves of samples were a broad endothermic transition peak (
