Starch, a natural storage polysaccharide of plant kingdom, has many industrial applications. However, native starch has some inherent shortages, which can be overcome by structural modification. Dialdehyde starch, one kind of oxidized starch produced by periodate oxidation, has good physical properties and bioactivities with wide applications in different fields. Dialdehyde starch is typically achieved by oxidizing native starch slurry through periodate oxidation under controlled reaction conditions. Several factors including the source of starch, the type of oxidant, the molar ratio of oxidant to starch, reaction temperature, reaction time and solution pH value can influence the synthesis of dialdehyde starch. Dialdehyde starch shows different spectroscopic/chromatographic characters and physicochemical properties from native starch. Moreover, dialdehyde starch exhibits good antioxidant activity, antimicrobial activity and cross-linking property. Based on these functional properties, dialdehyde starch has shown application potentials in food packaging, thermoplastic production, enzyme immobilization, heavy metal ion adsorption, drug delivery, wood adhesion and leather tanning. In this review, the preparation conditions, structural characteristics, physicochemical properties, functional properties and potential applications of dialdehyde starch are summarized for the first time. The future research and development prospects of dialdehyde starch are also discussed.
淀粉是植物王国中一种天然的储存多糖，具有许多工业应用。然而，天然淀粉存在一些固有缺陷，可以通过结构修饰来克服。双醛淀粉是通过高碘酸盐氧化在受控反应条件下氧化原淀粉浆而得到的一种氧化淀粉，具有良好的物理性质和生物活性，在不同领域有广泛的应用。双醛淀粉的合成通常是通过高碘酸盐氧化在受控反应条件下氧化原淀粉浆来实现的。包括淀粉来源、氧化剂类型、氧化剂与淀粉的摩尔比、反应温度、反应时间和溶液 pH 值在内的几个因素都会影响双醛淀粉的合成。双醛淀粉在光谱/色谱特征和物理化学性质方面与原淀粉不同。此外，双醛淀粉还表现出良好的抗氧化活性、抗菌活性和交联性能。基于这些功能特性，双醛淀粉在食品包装、热塑性生产、酶固定化、重金属离子吸附、药物输送、木材粘合和皮革鞣制等方面显示出应用潜力。本文首次综述了双醛淀粉的制备条件、结构特征、物理化学性质、功能性质和潜在应用。还讨论了双醛淀粉的未来研究和发展前景。
