Anthocyanins (ACNs) are natural pigments broadly used in the food industry due to their color, antioxidant, and antimicrobial properties, however, these pigments are degraded when exposed to high temperatures, light, oxygen, and alkaline conditions. Encapsulation of ACNs using native starches, modified starches, and their derivatives such as maltodextrins and starch nanoparticles is an alternative to increase the stability of these natural pigments. Thus, this review aims to comprehensively analyze the state of the art regarding the encapsulation of ACNs with native starches, modified starches, and their derivatives, with a special interest in the ACNs properties, 3 the main chemical treatments used to modify starches to be applied as encapsulants of ACNs, the main encapsulation techniques of ACNs using starches and derivatives, and the potential applications of these materials as active ingredients and colorants of food products, as well as additives to manufacture intelligent food packaging. ACNs can be encapsulated using starches, modified starches, and derivatives as wall materials by spray and freeze drying, the resulting materials have high encapsulating efficiency (> 80%). Particularly, maltodextrins are the main material used as encapsulants of ACNs. It is expected that the current review can reveal the fundamental aspects that should be considered for the encapsulation of ACNs with native starches, modified starches, and their derivatives, encouraging their use by the food industry.

包裹花青素的淀粉基材料：综述

花青素 (ACN) 是一种天然色素，因其颜色、抗氧化和抗菌特性而广泛用于食品工业，然而，这些色素在暴露于高温、光照、氧气和碱性条件下会降解。使用天然淀粉、改性淀粉及其衍生物（如麦芽糖糊精和淀粉纳米颗粒）封装 ACN 是增加这些天然色素稳定性的替代方法。因此，本综述旨在全面分析 ACNs 与天然淀粉、改性淀粉及其衍生物包封的最新技术，特别关注 ACNs 的性质，3 用于改性淀粉的主要化学处理方法作为 ACNs 的封装剂，ACNs 的主要封装技术是使用淀粉和衍生物，以及这些材料作为食品的活性成分和着色剂以及制造智能食品包装的添加剂的潜在应用。ACNs可以使用淀粉、改性淀粉及其衍生物作为壁材通过喷雾和冷冻干燥进行包封，所得材料的包封率高（> 80%）。特别是，麦芽糖糊精是用作 ACN 包封剂的主要材料。预计当前的审查可以揭示用天然淀粉、改性淀粉及其衍生物封装 ACN 应考虑的基本方面，鼓励食品工业使用它们。ACNs可以使用淀粉、改性淀粉及其衍生物作为壁材通过喷雾和冷冻干燥进行包封，所得材料的包封率高（> 80%）。特别是，麦芽糖糊精是用作 ACN 包封剂的主要材料。预计当前的审查可以揭示用天然淀粉、改性淀粉及其衍生物封装 ACN 应考虑的基本方面，鼓励食品工业使用它们。ACNs可以使用淀粉、改性淀粉及其衍生物作为壁材通过喷雾和冷冻干燥进行包封，所得材料的包封率高（> 80%）。特别是，麦芽糖糊精是用作 ACN 包封剂的主要材料。预计当前的审查可以揭示用天然淀粉、改性淀粉及其衍生物封装 ACN 应考虑的基本方面，鼓励食品工业使用它们。
