Abstract

Biopolymer hydrogel particles provide a wide range of advantages to food applications due to their highly hydrophilic nature, the ability to tailor micro-/macro-structure, and their complex rheology as dispersions. In food, dispersions of cross-linked hydrogel particles are increasingly used to create unique appearances or textures, novel aroma experiences, and/or for controlled-release applications. Mastering food biopolymer particle dispersions requires understanding of biopolymer physicochemistry, controlled microstructure creation, particle interactions that govern flow behavior, and the characterization techniques that give insight into the structure-function relationships across the different length scales. In the present review, recent progress in cross-linked food biopolymer hydrogels across these domains is presented with a particular focus on fluid gel dispersions and controlled release. We highlight how emerging technologies/techniques might enable new microstructural understanding or designer biopolymer sequences. Finally, we highlight how these developments help to fully unlock biopolymer hydrogel dispersions for food applications.

设计生物聚合物水凝胶颗粒分散体的微观结构,以在食品中提供功能
生物聚合物水凝胶颗粒由于其高度亲水性、定制微观/宏观结构的能力以及作为分散体的复杂流变性,为食品应用提供了广泛的优势。在食品中,交联水凝胶颗粒的分散体越来越多地用于创造独特的外观或质地,新颖的香气体验和/或控释应用。掌握食品生物聚合物颗粒分散需要了解生物聚合物的物理化学,控制微观结构的创建,控制流动行为的颗粒相互作用,以及在不同长度尺度上洞察结构-功能关系的表征技术。本文综述了交联食品生物聚合物水凝胶在这些领域的最新进展,重点介绍了流体凝胶的分散和控释。我们强调新兴技术/技术如何能够实现新的微观结构理解或设计生物聚合物序列。最后,我们强调这些发展如何有助于充分解锁食品应用的生物聚合物水凝胶分散体。

期刊介绍: Current Opinion in Colloid and Interface Science (COCIS) is an international journal that focuses on the molecular and nanoscopic aspects of colloidal systems and interfaces in various scientific and technological fields. These include materials science, biologically-relevant systems, energy and environmental technologies, and industrial applications. Unlike primary journals, COCIS primarily serves as a guide for researchers, helping them navigate through the vast landscape of recently published literature. It critically analyzes the state of the art, identifies bottlenecks and unsolved issues, and proposes future developments. Moreover, COCIS emphasizes certain areas and papers that are considered particularly interesting and significant by the Editors and Section Editors. Its goal is to provide valuable insights and updates to the research community in these specialized areas.
