The study used hemp protein isolate to make hemp protein hydrolysates (HPHs), which were combined with ferrous chloride to make hemp protein peptide iron chelates (HPH\u2010Fe). The HPH\u2010Fe were structurally characterized and analyzed for stability. The strongest ferrous ion\u2010binding fraction HPH\u2010I (&lt;3\u00a0kDa) was isolated by ultrafiltration, and Sephadex G\u201015 was used to obtain fractions with high ferrous ion\u2010binding capacity (82.47%), identified by amino acid sequences as QASSDGFEWVSFK (1482.31\u00a0Da), ARVDWKETPE (1223.53\u00a0Da), ILLPSF (719.34\u00a0Da), and WLNGGP (643.32\u00a0Da). Aspartic acid, lysine, glutamic acid, glycine, and histidine in HPH\u2010Fe were involved in the chelation reaction. HPH\u2010Fe maintained a good chelation rate at 25\u201365\u00b0C, pH\u00a0=\u00a04.0\u20137.0, stability during 35 days of storage at ambient temperature, and in vitro digestion tolerance. This study presents HPH\u2010Fe as a potential alternative to chemical iron supplements in food.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
