Abstract

This study evaluated the effects of incorporating spirulina algae powder (SAP) at 3%, 6%, and 9% into quinoa flour (QF) blends to produce gluten-free biscuits and snacks, compared to a 100% QF control. The chemical composition, mineral and amino acid content, antioxidant capacity, starch gelatinization, color, baking quality, sensory properties, and texture were analyzed. SAP was found to have high protein (62.50%), fat (5.92%), and ash (12.90%) content. Increasing the SAP concentration in QF blends resulted in a dose-dependent enhancement in the nutritional value of the biscuits and snacks. Farinograph analysis indicated a positive relationship between SAP percentage and water absorption. The inclusion of SAP significantly altered differential scanning calorimetry (DSC) and viscoamylograph parameters. Biscuit weight, volume, and specific volume decreased with increasing SAP levels. Hunter color measurements showed a SAP concentration-dependent darkening effect, which was supported by sensory assessments. The 9% SAP biscuits and snacks exhibited the greatest antioxidant activity, with DPPH values of 50.18 and 43.6 µmol/g, respectively, and reducing power values of 41.49 and 36.58 µmol/g, respectively. Overall, while all samples were deemed acceptable, the 3% and 6% SAP formulations generally demonstrated better sensory characteristics and improved nutritional profiles, suggesting their potential as suitable options for individuals with gluten sensitivities.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
