Food researchers are currently showing a growing interest in in vitro digestibility studies due to their importance for obtaining food products with health benefits and ensuring a balanced nutrient intake. Various bioactive food compounds are sensitive to the digestion process, which results in a lower bioavailability in the gut. The main objective of structured food delivery systems is to promote the controlled release of these compounds at the desired time/place, in addition to protecting them during digestion processes. This review provides an overview of the influence of structured delivery systems on the in vitro digestive behavior. The main delivery systems are summarized, the pros and cons of different structures are outlined, and examples of several studies that optimized the use of these structured systems are provided. In addition, we have reviewed the use of plant-based systems, which have been of interest to food researchers and the food industry because of their health benefits, improved sustainability as well as being an alternative for vegetarian, vegan and consumers suffering from food allergies. In this context, the review provides new insights and comprehensive knowledge regarding the influence of plant-based structured systems on the digestibility of encapsulated compounds and proteins/polysaccharides used in the encapsulation process.
由于体外消化率研究对于获得具有健康益处的食品产品和确保均衡的营养摄入具有重要意义，食品研究人员目前对其表现出越来越大的兴趣。各种生物活性食品化合物对消化过程很敏感，这导致在肠道中的生物利用度降低。结构化食品输送系统的主要目标是促进这些化合物在所需的时间/地点的控制释放，并在消化过程中对其进行保护。本综述概述了结构化输送系统对体外消化行为的影响。总结了主要的输送系统，概述了不同结构的优缺点，并提供了一些优化这些结构化系统使用的研究示例。此外，我们还回顾了基于植物的系统的使用，由于其健康益处、提高可持续性以及作为素食者、纯素食者和食物过敏消费者的替代品，这些系统引起了食品研究人员和食品行业的兴趣。在这种情况下，该综述提供了关于植物结构化系统对封装化合物和用于封装过程的蛋白质/多糖的消化率的影响的新见解和全面知识。
