Peptide　self-assembly,　due　to　its　diverse　supramolecular　nanostructures,　excellent　biocompatibility,　and　bright　application　prospects,　has　received　wide　interest　from　researchers　in　the　fields　of　biomedicine　and　green　life　technology　and　the　food　industry.　Driven　by　thermodynamics　and　regulated　by　dynamics,　peptides　spontaneously　assemble　into　supramolecular　structures　with　different　functional　properties.　According　to　the　functional　properties　derived　from　peptide　self-assembly,　applications　and　development　directions　in　foods　can　be　found　and　explored.　Therefore,　in　this　review,　the　regulatory　mechanism　is　elucidated　from　the　perspective　of　self-assembly　thermodynamics　and　dynamics,　and　the　functional　properties　and　application　progress　of　peptide　self-assembly　in　foods　are　summarized,　with　a　view　to　more　adaptive　application　scenarios　of　peptide　self-assembly　in　the　food　industry.　©　2024　American　Chemical　Society
