چکیده

Abstract Gluten-free bakery products are usually deficient in dietary fiber and inferior sources of protein. Studies that have assessed sensory characterization prepared with orange pomace scarce. This study evaluated the employment 30% rice-based pregelatinized composite flours (containing 15, 25 or 35% blended 5% soy protein isolate) on gluten-free biscuits. The target was investigation nutritional profile consumer’s acceptance three short dough sweet biscuit samples. Thermoplastic extrusion an efficient unit operation for elaboration a new ingredient which by-product rich total component high level were employed. All this can be labeled as claimed content, well two samples source. Also, all biscuits presented low moisture water activity, being microbiologically stable to room temperature (25 ± 2 °C). Complementarily, results microbiological evaluations [(coagulase-positive Staphylococcus , thermotolerant coliform (45 °C) Salmonella sp. (absence g)] their comparison Brazilian standards legislation attested safety. Concerning analysis, adults’ showed flavor attribute might responsible increasing overall impression score sample. In contrast, children’s they did not distinguish ( p ≥ 0.05) analyzed.

Physicochemical Properties of Gluten-free Pancakes from Rice and Sweet Potato Flours

Gluten-free pancakes were prepared using rice flour and rice flour replaced with various amounts, at 10, 20 and 40%, of sweet potato flour. Textural properties of the cooked pancakes, such as hardness and chewiness generally increased with time after cooking, whereas they decreased with increased sweet potato flour replacement. On the other hand, cohesiveness decreased with time, but increased ...
