Bilayer pouches were fabricated with chitosan (CS)-fish gelatin (FG) mixture containing epigallocatechin gallate (EGCG) deposited over the poly lactic acid (PLA) film through solvent casting and electrospinning techniques. Pickering emulsions (PE) of Asian seabass depot fat oil stabilized by zein colloidal particles were packed in bilayer pouches and stored at 28 ± 2 °C. The PE packed in pouch containing EGCG had higher emulsion and oxidative stability after 30 days of storage as witnessed by the smaller droplet size and lower values of thiobarbituric acid reactive substances, peroxide, conjugated diene and volatile compounds in comparison with control (PE packed in monolayer PLA pouch) ( < 0.05). EGCG incorporated pouch retained more linoleic acid (C18:2 n-6) and linolenic acid (C18:3 n-9) in emulsion than PLA pouch. Therefore, pouch from bilayer PLA/CS-FG films comprising EGCG could serve as active packaging and extended the shelf life of Pickering emulsion.

亚洲鲈鱼水包油皮克林乳液的储存稳定性，该乳液装在由含有表没食子儿茶素没食子酸酯的聚乳酸/壳聚糖-明胶混合物制成的静电纺丝和溶剂浇铸双层膜制成的小袋中
通过溶剂浇铸和静电纺丝技术，将含有表没食子儿茶素没食子酸酯（EGCG）的壳聚糖（CS）-鱼明胶（FG）混合物沉积在聚乳酸（PLA）薄膜上，制成双层袋。将玉米醇溶蛋白胶体颗粒稳定的亚洲鲈鱼储存脂肪油的皮克林乳液 (PE) 包装在双层袋中并储存在 28 ± 2 °C 下。与对照（单层 PE 包装）相比，含有 EGCG 的袋装 PE 在储存 30 天后具有更高的乳化稳定性和氧化稳定性，表现为较小的液滴尺寸和硫代巴比妥酸反应物质、过氧化物、共轭二烯和挥发性化合物的含量较低。 PLA 袋）（< 0.05）。与 PLA 袋相比，掺有 EGCG 的袋在乳液中保留了更多的亚油酸 (C18:2 n-6) 和亚麻酸 (C18:3 n-9)。因此，含有 EGCG 的双层 PLA/CS-FG 薄膜制成的袋子可以作为活性包装并延长 Pickering 乳液的保质期。
