Developing　emulsifier-free　intelligent　films　constitutes　a　dependable　strategy　for　securing　food　supply　chain　safety.　Here,　zinc-binding　peptides　derived　from　Crimson　Snapper　scales　(CSSP-Zn)　and　Jufeng　grape　pomace　anthocyanin　(JGA)　were　incorporated　into　a　gelatin　(GL)　matrix　to　fabricate　three　types　of　films:　GL　film,　GL　film　with　CSSP-Zn　and　GL　film　with　both　JGA　and　CSSP-Zn.　The　GL　film　is　a　pure　GL　film,　while　the　GL　film　incorporating　CSSP-Zn　exhibits　antimicrobial　activity,　and　the　GL　film　containing　both　JGA　and　CSSP-Zn　functions　as　an　antimicrobial,　pH-responsive　intelligent　film.　Compared　with　the　pure　GL　film,　incorporating　CSSP-Zn　and　JGA　enhanced　mechanical　strength,　water　resistance　and　barrier　properties　via　hydrogen　bonding　and　Zn2+　ligand　interactions.　The　intelligent　film　exhibited　long-lasting　antimicrobial　activity,　maintaining　potent　microbicidal　efficacy　even　after　3　months　of　storage.　Additionally,　it　demonstrates　excellent　antioxidant　properties　(DPPH　and　ABTS　scavenging　rates　＞　83　%),　pH-responsive　color　changes,　cytocompatibility　(cell　viability　＞　80　%)　and　biodegradability　(degradable　within　15　days　in　soil).　When　applied　to　Penaeus　orientalis,　the　intelligent　film　effectively　shields　the　shrimp　from　UV　light,　free　radicals　and　microbes,　delaying　melanosis　and　spoilage　while　preserving　texture,　sensory　attributes　and　nutrient　profile,　ultimately　extending　shelf　life.　Overall,　incorporating　CSSP-Zn　and　JGA　can　prepare　a　high-performance,　eco-friendly　GL-based　intelligent　film,　providing　valuable　insights　for　sustainable　food　packaging.　©　2025
