Tóm tắt

 Iron deficiency is a widespread global issue that leads to nutritional disorders and iron deficiency anemia (IDA). In this study, quinoa protein peptide (QPP) was selected to design a novel iron supplement, quinoa protein peptide‑iron chelate (QPP-Fe). Notably, QPP with a molecular weight of <
 2000 Da, prepared using Alcalase, exhibited the highest iron chelation ratio of 79.2 ± 0.36 mg/g. Furthermore, FTIR, UV-Vis, CD, and fluorescence spectroscopy results indicated that the addition of Fe
