Peptides　are　functional　active　fragments　of　proteins　which　can　provide　nutrients　needed　for　human　growth　and　development,　and　they　also　have　unique　physiological　activity　characteristics　relative　to　proteins.　Bioactive　peptides　contain　a　great　deal　of　development　potential.　More　specifically,　food-derived　bioactive　peptides　have　the　advantages　of　a　wide　variety　of　sources,　unique　structures,　high　efficiency　and　safety,　so　they　have　broad　development　prospects.　This　review　provides　an　overview　of　the　current　advances　regarding　the　preparation,　functional　characteristics,　and　structure-　activity　relationships　of　food-derived　bioactive　peptides.　Moreover,　the　prospects　for　the　future　development　and　application　of　food-derived　bioactive　peptides　are　discussed.　This　review　may　provide　a　better　understanding　of　foodderived　bioactive　peptides,　and　some　constructive　inspirations　for　further　research　and　applications　in　the　food　industry.
