Abstract：

The　effects　of　freeze–thaw　(F-T)　cycles　on　the　shape　retention　of　antifreeze　peptides-based　surimi　ink　(ASI)　3D　structures　were　analyzed.　The　results　showed　that　the　ASI　3D　structure　has　good　shape　retention　ability,　and　the　width,　height,　weight,　and　water　holding　capacity　were　22.42　mm,　21.07　mm,　9.99　g,　and　68.30　%　even　after　F-T　4　times,　respectively.　The　average　area　and　equivalent　diameter　of　ice　crystals　in　ASI　3D　structures　only　expand　from　0.001　mm2　and　0.040　mm　to　0.015　mm2　and　0.139　mm,　respectively.　The　α-helix　and　β-sheet　of　myofibrillar　protein　in　ASI　3D　structure　were　slightly　decreased　by　44.16　±　0.98　%　to　33.33　±　0.92　%　and　increased　by　18.28　±　4.45　%　to　24.43　±　1.60　%,　respectively.　The　chemical　bond　and　protein　interaction　have　changed　to　some　extent.　AFPs　can　prevent　denaturation　and　juice　loss　of　surimi　3D　structures　after　F-T.　The　results　provide　theoretical　guidance　for　maintaining　the　shape　retention　of　frozen　3D　food　structures.　©　2022　Elsevier　Ltd
