Orange juice residues as dietary fiber source for foods

Food snacks using powdered residues from the orange juice industry as a source of dietary fiber were formulated. Six formulations utilizing powdered orange residues with three different moisture levels (25%, 15% and 10%) were elaborated. There were used two basic blends. The first one was 33.3% of orange dry powder, 33.3% of honey, 16.6% of roasted peanut, 16.6% of raisins; the second one was 28.6% of orange powder, 35.7% of honey, 17.85% of roasted peanut, 17.85% of raisins. Snacks had spherical shape with 2.5 cm diameter and a weight close to 10g. The snack moisture was between 12.6 and 17.4%, and their aw between 0.65 and 0.71. The snack chemical composition, on dry matter basis, was 1.6 and 1.9% of ash; 12.3 and 15.2% of lipids; 6.1 and 7.1% of proteins; and 56.2 to 59.6% of carbohydrates; the caloric contribution (calculated) was between 326.8 and 342.9 kcal/100g. The powdered orange residue had 64% of total dietary fiber, 54% of insoluble dietary fiber and 10% of soluble dietary fiber. In the snack the fiber amount fluctuated between 20 and 26% of total dietary fiber; 18 and 22% of insoluble dietary fiber, and 3.0 and 4.5% of soluble dietary fiber. The snack with the higher content of orange residue presented the higher content of dietary fiber. The snacks were well accepted by a sensory panel, without showing differences among treatments.
