AbstractSecondary varieties of date from Tunisia are underutilized due to their low commercial quality. Fiber concentrates (DFC) can be obtained from these fruits after a steam pretreatment. DFCs were evaluated as a source of antioxidant dietary fiber for bakery products. Muffins were prepared with 2.5 and 5% flour substitution with DFCs obtained by treatments at 165 and 180C. The DFC-doughs presented a similar yield to the control but the muffins reached a lower volume. The density increase did not imply an increase in texture. In fact, the muffins with DFC-165 were the softest tested, although they had lower cohesiveness and springiness. The proximate composition was similar among samples. The DFC-muffins had higher antioxidant capacity than the control, and obtained good scores in the sensory evaluation. DFC-165 is a valuable ingredient for baked goods, but its effect on fat rancidity and staling delays should be confirmed.
