Although complex coacervation could improve the water solubility, thermal stability, bioavailability, antioxidant activity and antibacterial activity of essential oils (EOs). However, some wall materials (such as proteins and polysaccharides) with water solubility and hydrophobic nature limited their application in complex coacervation. In order to improve the properties of EO complex coacervates, some efficient physical field technology was proposed. This paper summarizes the application and functional properties of EOs in complex coacervates, formation and controlled-release mechanism, as well as functions of EO complex coacervates. In particular, efficient physical field technology as innovative technology, such as high pressure, ultrasound, cold plasma, pulsed electric fields, electrohydrodynamic atomization and microwave technology improved efficient and quality attributes of EO complex coacervates are reviewed. The physical fields could modify the gelling, structural, textural, emulsifying, rheological properties, solubility of wall material (proteins and polysaccharides), which improve the properties of EO complex coacervates. Overall, EOs complex coacervates possess great potential to be used in the food industry, including high bioavailability, excellent antioxidant capacity and gut microbiota in vivo, masking the sensation of off-taste or flavor, favorable antimicrobial capacity.
虽然复杂凝聚可以提高精油（EOs）的水溶性、热稳定性、生物利用度、抗氧化活性和抗菌活性。然而，一些具有水溶性和疏水性的壁材（如蛋白质和多糖）限制了它们在复杂凝聚中的应用。为了提高 EO 复合凝聚物的性能，提出了一些有效的物理场技术。本文总结了 EOs 在复合凝聚物中的应用和功能特性、形成和控制释放机制以及 EO 复合凝聚物的功能。特别是，作为创新技术的高效物理场技术，如高压、超声、冷等离子体、脉冲电场、电动力学雾化和微波技术，改善了 EO 复合凝聚物的高效和质量特性。物理场可以修饰凝胶、结构、质地、乳化、流变特性、壁材（蛋白质和多糖）的溶解度，从而改善 EO 复合凝聚物的性能。总的来说，EO 复合凝聚物具有很大的潜力应用于食品工业，包括高生物利用度、体内优异的抗氧化能力和肠道微生物群、掩盖不良味道或风味的感觉、良好的抗菌能力。
