Xylo-oligosaccharides (XOS) are considered as functional oligosaccharides and have great prebiotic potential. XOS are the degraded products of xylan prepared via chemical, physical or enzymatic degradation. They are mainly composed of xylose units linked by β-1, 4 bonds. XOS not only exhibit some specific physicochemical properties such as excellent water solubility and high temperature resistance, but also have a variety of functional biological activities including anti-inflammation, antioxidative, antitumor, antimicrobial properties and so on. Numerous studies have revealed in the recent decades that XOS can be applied to many food and feed products and exert their nutritional benefits. XOS have also been demonstrated to reduce the occurrence of human health-related diseases, improve the growth and resistance to diseases of animals. These effects open a new perspective on XOS potential applications for human consumption and animal production. Herein, this review aims to provide a general overview of preparation methods for XOS, and will also discuss the current application of XOS to human and animal health field.
低聚木糖（XOS）被认为是功能性低聚糖，具有巨大的益生元潜力。低聚木糖是通过化学、物理或酶促降解制备的木聚糖的降解产物。它们主要由通过β-1,4键连接的木糖单元组成。低聚木糖不仅具有一些特定的物理化学性质，如优异的水溶性和耐高温性，还具有多种功能性生物活性，包括抗炎、抗氧化、抗肿瘤、抗菌等特性。近几十年来的大量研究表明，低聚木糖可应用于许多食品和饲料产品，并发挥其营养益处。低聚木糖还被证明可以减少与人类健康相关疾病的发生，提高动物的生长和抗病能力。这些作用为低聚木糖在人类消费和动物生产中的潜在应用开辟了新的前景。在此，本综述旨在对低聚木糖的制备方法进行概述，并讨论低聚木糖目前在人类和动物健康领域的应用。
