Alginate is a biopolymer with film‐forming properties that can be used as food packaging material. Norbixin is a carotenoid with antioxidant properties, commonly used as a natural food coloring. The research objective was to create calcium‐crosslinked alginate films and incorporated with norbixin concentrations (N%) of 0.05%, 0.10%, and 0.50% (g norbixin/g alginate). The polymer matrix helped to retard the thermal degradation of norbixin during the drying process and decreased leaching losses during the crosslinking process. The addition of norbixin influenced film opacity in ultraviolet light (all N%) and visible light (higher N%), causing an increase in red‐yellow coloration. Only the higher N% influenced the water vapor permeability of film. Norbixin thus improved the overall barrier properties of the crosslinked sodium alginate film, with a 0.50 N% showing the most promising results. When used as sunflower oil packaging, films with a N% above 0.10 provided pro‐oxidant activity during storage.

将诺必信掺入与Ca2 +交联的可生物降解藻酸盐薄膜中：促氧化剂作用
海藻酸盐是具有成膜特性的生物聚合物，可用作食品包装材料。Norbixin是一种具有抗氧化特性的类胡萝卜素，通常用作天然食用色素。研究目标是制造钙交联的藻酸盐薄膜，并掺入0.05％，0.10％和0.50％（克诺比辛/克藻酸盐）的去甲毒素浓度（N％）。聚合物基质有助于在干燥过程中抑制降冰片毒素的热降解，并减少交联过程中的浸出损失。诺必信的加入影响了紫外线（全部N％）和可见光（更高的N％）中膜的不透明度，导致了红黄颜色的增加。仅较高的N％影响膜的水蒸气渗透性。因此，诺必信改善了交联海藻酸钠薄膜的整体阻隔性能，值为0。50 N％显示最有希望的结果。当用作葵花籽油包装时，N％高于0.10的薄膜在储存过程中具有促氧化活性。
