Arabinoxylans (AXs) and their derived arabinoxylooligosaccharides (AXOS) are valuable functional biomolecules with promising applications in the food, brewing, and packaging industries. However, inconsistencies in extraction techniques, structural characterization, and industrial applicability remain key challenges. This review comprehensively examines various AX extraction methods from brewer's spent grain (BSG), including chemical, enzymatic, steam explosion, ultrasound-assisted, and microwave-assisted techniques, emphasizing their impact on molecular characteristics such as molecular weight, monosaccharide composition, and structural features. Furthermore, the biological activities of AX, including prebiotic, immunomodulatory, hypoglycemic, and antioxidant properties, are analyzed in relation to their structural variations. Despite their potential, knowledge gaps persist regarding how different extraction techniques influence AX bioactivity and functionality. Additionally AX is increasingly explored in synbiotic formulations, food products, beer, and biodegradable films. This review addresses these gaps by consolidating current knowledge on AX extraction, characterization, and functionality, highlighting the need for standardized methodologies and further research to optimize its industrial applications.
阿拉伯木聚糖（AXs）及其衍生的阿拉伯木寡糖（AXOS）是有价值的功能性生物分子，在食品、酿造和包装行业有着广阔的应用前景。然而，提取技术、结构表征和工业适用性方面的不一致仍然是关键挑战。本综述全面考察了从啤酒糟（BSG）中提取各种AX的方法，包括化学法、酶法、蒸汽爆破法、超声辅助法和微波辅助法，强调了这些方法对分子量、单糖组成和结构特征等分子特性的影响。此外，还分析了AX的生物活性，包括益生元、免疫调节、降血糖和抗氧化特性，以及它们与结构变化的关系。尽管AX具有潜力，但关于不同提取技术如何影响AX生物活性和功能的知识空白仍然存在。此外，AX在合生元配方、食品、啤酒和可生物降解薄膜中的应用也越来越受到关注。本综述通过整合当前关于AX提取、表征和功能的知识，填补了这些空白，强调了标准化方法的必要性以及进一步研究以优化其工业应用的重要性。
