Phytochemicals are plant-derived chemicals that have a number of protective or health-promoting properties. However, their health benefits and thus commercial potential can be restricted due to their instability to environmental factors such as moisture, heat, light, oxygen etc. A common approach to improve stability is via encapsulation whereby the phytochemical is encased inside a wall material, thereby forming a protective barrier between the phytochemical and the external environment. The impact of a wide range of wall materials and their combinations on the stability of various phytochemicals has been studied in the last twenty years. This review focuses on the specific inherent physicochemical characteristics of the wall material as well as the encapsulation process dependant physical characteristics that has shown to have the greatest impact on the stability of encapsulated phytochemicals. The information contained in this review could assist researchers in addressing some of the most important considerations when designing a wall material for increased phytochemical stability.
植物化学物质是源自植物的化学物质，具有多种保护或促进健康的特性。然而，由于它们对环境因素（如水分、热量、光照、氧气等）的不稳定性，其健康益处和因此的商业潜力可能会受到限制。提高稳定性的常用方法是通过包封，即将植物化学物质封装在壁材料内部，从而在植物化学物质和外部环境之间形成保护屏障。在过去的二十年中，已经研究了各种壁材料及其组合对各种植物化学物质稳定性的影响。本综述重点介绍了壁材料的特定固有物理化学特性以及封装过程相关的物理特性，这些特性已被证明对封装植物化学物质的稳定性有最大的影响。本综述中包含的信息可以帮助研究人员在设计用于提高植物化学物质稳定性的壁材料时，解决一些最重要的考虑因素。
