An　active　film　from　silver　carp　skin　gelatin　incorporated　with　green　tea　extract　(GTE)　was　developed.　The　effects　of　GTE　concentrations　including　0.3　and　0.7%　(w/v)　on　the　film　properties　were　determined　by　measuring　total　polyphenolic　content,　antioxidant　activity　and　physical　properties.　The　findings　of　this　study　showed　that　the　incorporation　of　GTE　into　gelatin　films　enhanced　the　total　phenolic　content,　DPPH　radical　scavenging　activity　and　reducing　power.　However,　DPPH　radical　scavenging　activity　and　reducing　power　decreased　during　storage.　As　regards　the　physical　properties,　higher　GTE　content　incorporated　into　gelatin　films　revealed　significantly　higher　tensile　strength　and　lower　elongation　at　break,　water　solubility　and　water　vapor　permeability,　but　no　difference　in　thickness.　Gelatin-GTE　films　exhibited　lower　light　transmission　in　UV　light,　lower　percent　transmittance　and　higher　transparency　value　compared　to　control　film.　Moreover,　protein　patterns　of　gelatin-GTE　films　had　no　changes.　The　thermal　stability　of　gelatin-GTE　films　was　improved　and　grew　with　the　increasing　concentration　of　GTE.　FTIR　spectra　indicated　that　protein-polyphenol　interactions　were　involved　in　the　gelatin-GTE　films.　Smooth　and　homogeneous　surface　and　compact-structure　were　observed　in　gelatin-GTE　films.　Thus,　the　addition　of　GTE　into　gelatin　film　improved　the　antioxidant　activity　and　directly　affected　the　properties　most　likely　due　to　the　interactions　between　gelatin　and　GTE.　(c)　2012　Elsevier　Ltd.　All　rights　reserved.
