To explore the use of starfish gelatin (SFG) films as a biodegradable material, SFG from starfish was extracted and used as a film material. In addition, to provide antimicrobial activity and enhanced flavor of SFG films, vanillin was incorporated. As the concentration of vanillin increased, the tensile strength of the films increased and water vapor permeability decreased. With regard to the structural characteristics of SFG films containing vanillin, the microstructure of the SFG films was not affected by the addition of vanillin. In addition, the SFG films containing vanillin exhibited antimicrobial activity against . As the application of the SFG films, crab sticks were packed with SFG films containing 0.05% vanillin. During storage, the populations of inoculated on crab sticks wrapped with SFG films containing vanillin were lower than those on the control sample, suggesting that SFG films containing vanillin can be useful in active food packaging.
为探索将海星明胶（SFG）薄膜用作可生物降解材料，从海星中提取了SFG并用作薄膜材料。此外，为赋予SFG薄膜抗菌活性并增强风味，添加了香草醛。随着香草醛浓度的增加，薄膜的拉伸强度增加，水蒸气透过率降低。关于含香草醛的SFG薄膜的结构特性，香草醛的添加未影响SFG薄膜的微观结构。此外，含香草醛的SFG薄膜对……表现出抗菌活性。作为SFG薄膜的应用，用含0.05%香草醛的SFG薄膜包装蟹棒。在储存期间，接种在包裹有含香草醛SFG薄膜的蟹棒上的……数量低于对照样品上的数量，这表明含香草醛的SFG薄膜可用于活性食品包装。
