摘要

天然色素为花朵、水果和蔬菜提供了一系列吸引人的颜色,同时显示出潜在的有益健康效果。相比之下,合成食用色素通常被认为与不良健康影响有关,但已知在加工和储存过程中具有相对较高的颜色稳定性。与人工色素不同,天然色素有些不稳定,容易受到化学和酶的降解,导致颜色损失加剧。因此,它们作为颜料的使用受到限制,并且正在探索水胶体的稳定性。水胶体除了具有织构性外,还会与天然色素相互作用,影响其稳定性。因此,水胶体可以提高颜料的化学和物理稳定性,从而增强颜色的稳定性。本文综述了利用水胶体稳定天然色素(花青素、甜菜素、胡萝卜素、c -藻青素和叶绿素)的最新研究进展,包括水胶体的性质、色素结构、稳定方法和机理。

Utilization of hydrocolloids for the stabilization of pigments from natural sources

Natural pigments provide a range of appealing colors to flowers, fruits, and vegetables while exhibiting potential beneficial health effects. In contrast, synthetic food colorants are often suggested to be associated with adverse health effects yet are known to have relatively high color stability during processing and storage. Unlike artificial colorants, natural pigments are somewhat unstable and susceptible to chemical and enzymatic degradation, leading to enhanced color loss. Therefore, their use as pigments is constrained, and stabilization by hydrocolloids is being explored. In addition to the texturizing properties of hydrocolloids, they can interact with natural pigments, affecting their stability. Therefore, hydrocolloids can improve the chemical and physical stability of pigments, resulting in enhanced color stability. This review summarizes up-to-date information regarding the stabilization of natural pigments such as anthocyanins, betalains, carotenes, C-phycocyanins, and chlorophylls, using hydrocolloids, in relation to the hydrocolloid properties, pigment structure, and stabilization methods and mechanisms.

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.
