Abstract

Exploring microalgae-based functional ingredients for food preservation and quality enhancement meets the consumers' demand for healthier staple food. This study developed nutrient-fortified composite systems (SP@Cur) by loading curcumin (Cur) onto Spirulina platensis (SP) as bread improvers to enhance storage stability and flavor attributes. The results showed that as the Cur concentration in composite systems increased from 200 μg/mL (L-SP@Cur) to 800 μg/mL (H-SP@Cur), the loading capacity of SP@Cur increased from 23.22 % to 57.02 %. After the addition of SP@Cur to bread, H-SP@Cur improved the bread's textural properties, and effectively extended bread's shelf life from 6 to 10 days during storage at room temperature. Furthermore, gas chromatography–mass spectrometry (GC–MS) and molecular docking analysis further confirmed Cur reduced the fishy odorants caused by SP via competitive inhibition with Hexanal and 1-Octen-3-ol, thereby improving the sensory palatability of bread. This work provides the feasibility of employing SP@Cur as multifunctional ameliorant in shelf-stable staple foods. • Spirulina platensis -curcumin system (SP@Cur) was built and added to bread. • H-SP@Cur improved bread's microstructure, texture and delayed starch digestion. • Addition of H-SP@Cur enhanced bread's nutrition and extended its shelf life. • H-SP@Cur reduced fishy odorants (Hexanal and 1-Octen-3-ol) in SP-fortified bread. • SP@Cur endowed nutritional fortification and flavor improvement with bread.

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.
