This　study　investigated　the　impacts　of　growth　seasons　and　maturity　stages　on　the　processing　properties　of　starch　isolated　from　‘Dwarf　Cavendish’　banana.　The　analysis　revealed　that　seasonal　variations　and　maturity　stages　had　significant　impacts　on　the　characteristics　of　the　starch.　Summer　banana　starch　(SBS)　demonstrated　a　more　ordered　structure,　enhanced　thermal　stability,　higher　viscosity,　and　increased　content　of　resistant　starch　(RS)　compared　to　winter　banana　starch　(WBS).　Moreover,　several　parameters　of　starch　significantly　increased　during　the　maturity　stage　progressed　from　60　to　90　%.　Specifically,　the　relative　crystallinity　rose　from　27.50　to　32.13　%　in　SBS　and　from　17.05　to　22.19　%　in　WBS.　The　peak　viscosity　increased　from　5064　to　5354　cP　in　SBS　and　from　4992　to　5086　cP　in　WBS.　Additionally,　RS　content　increased　from　85.20　to　90.71　%　in　SBS　and　from　80.55　to　86.99　%　in　WBS.　Principal　component　analysis　showed　that　SBS　at　90　%　maturity　exhibited　high　thermal　stability,　viscosity,　and　RS　content,　positioning　it　as　a　multifunctional　source　suitable　for　starch-derived　food　products.　This　research　presented　an　understanding　of　the　variations　in　properties　of　banana　starches　during　different　growth　seasons　and　maturity　stages,　providing　valuable　insights　for　their　application　in　food　products.　©　2025　The　Authors
