Proteins and polysaccharides have been widely used as wall materials to prepare novel carriers for the encapsulation of a single bioactive component or co-encapsulation of different bioactive components. Emulsion-filled gel beads generally contain three essential components: oil droplets, interface membrane of emulsifier, and gel matrix. In this study, emulsion-filled gel beads were prepared by the combination of heat-denatured whey protein isolate (WPI)'s emulsification and alginate's gelation at various protein and oil contents, in order to discuss simultaneous encapsulation, protection and release of hydrophobic α-tocopherol and amphiphilic resveratrol. High efficiency for the co-encapsulation of resveratrol and α-tocopherol was achieved for the emulsion-filled gel beads containing 1% WPI and 1%–4% oil. WPI content was more important than the content of oil for the protection of resveratrol while the content of oil was more important for the encapsulation and protection of α-tocopherol during storage. The release of α-tocopherol was <20% while resveratrol was rapidly released during digestion. Resveratrol remained 73% after released from the emulsion-filled gel beads containing 1% WPI and 1%–2% oil for 6 h. These results should be useful for the development of biopolymer-based carriers for the delivery of different bioactive components.

蛋白质和多糖已被广泛用作墙壁材料，以制备用于封装单个生物活性成分或共同封装不同生物活性成分的新型载体。乳液填充的凝胶珠通常包含三个基本成分：油滴，乳化剂的界面膜和凝胶基质。在这项研究中，结合热变性乳清蛋白分离物（WPI）的乳化作用和藻酸盐在各种蛋白质和油含量下的胶凝作用，制备了乳液填充的凝胶珠，以讨论疏水性α的同时包封，保护和释放-生育酚和两亲白藜芦醇。含有1％WPI和1％–4％油的乳液填充凝胶珠实现了白藜芦醇和α-生育酚的共包封的高效率。对于保护白藜芦醇，WPI的含量比油的含量更重要，而在存储过程中油的含量对α-生育酚的包封和保护更重要。α-生育酚的释放<20％，而白藜芦醇在消化过程中迅速释放。白藜芦醇从含有1％WPI和1％–2％油的乳液填充凝胶珠中释放6小时后仍保持73％。这些结果对于开发用于递送不同生物活性组分的基于生物聚合物的载体应该是有用的。白藜芦醇从含有1％WPI和1％–2％油的乳液填充凝胶珠中释放6小时后仍保持73％。这些结果对于开发用于递送不同生物活性组分的基于生物聚合物的载体应该是有用的。白藜芦醇从含有1％WPI和1％–2％油的乳液填充凝胶珠中释放6小时后仍保持73％。这些结果对于开发用于递送不同生物活性组分的基于生物聚合物的载体应该是有用的。
