Spray-drying is known as a common and economical technique for the encapsulation of various nutrients and bioactive compounds. However, shear and thermal tensions during atomization and dehydration, as well as physicochemical instability during storage, result in a loss of these compounds. As a solution, bioactives are stabilized into different carriers, among which proteins and peptides are of particular importance due to their functional properties, surface activity, and film/shell formability around particles. Given the importance of stabilization of bioactive compounds during spray drying, this paper focuses on the role of composition and type of carriers, as well as the characteristics and efficiency of various protein-based carriers in the encapsulation and maintaining of physicochemical, structural, and functional properties, along with biological activity of bioactive compounds (e.g., oleoresins, sterols, polyphenols, anthocyanins, carotenoids, probiotics, and peptides), and nutrients (e.g., vitamins, fatty acids and minerals) alone or in combination with other biopolymers.
喷雾干燥是一种常见且经济的技术，用于封装各种营养物质和生物活性化合物。然而，在雾化和脱水过程中会产生剪切和热张力，并且在储存过程中会发生物理化学不稳定性，导致这些化合物的损失。作为一种解决方案，生物活性物质被稳定到不同的载体中，其中蛋白质和肽由于其功能特性、表面活性以及在颗粒周围形成膜/壳的能力而尤为重要。鉴于在喷雾干燥过程中稳定生物活性化合物的重要性，本文重点介绍了载体的组成和类型、以及各种基于蛋白质的载体的特性和效率在封装和维持生物活性化合物（例如，精油、固醇、多酚、花青素、类胡萝卜素、益生菌和肽）以及营养物质（例如，维生素、脂肪酸和矿物质）的物理化学、结构和功能特性以及生物活性方面的作用，单独或与其他生物聚合物结合使用。
