从大麦中提取的β-葡聚糖主要含有β-（1，3 - 1，4）-D-葡聚糖，由于其广泛的生物活性，包括降低血脂水平，被广泛用作补充剂和食品添加剂。在这项研究中，研究了β-葡聚糖的抗氧化活性，以评估与β-葡聚糖相关的潜在新益处，因为氧化应激被认为是各种疾病和衰老的主要原因之一。从大麦中提取的β-葡聚糖具有显著的抗氧化活性。抗氧化活性的量受不同生理特性的影响（例如，β-葡聚糖的结构和分子大小），这取决于来源和所用的提取方法。β-葡聚糖的抗氧化活性明显高于用作食品添加剂的各种聚合物。这些结果表明，β-葡聚糖有希望作为补充剂和食品添加剂的聚合物赋形剂，具有抗氧化和其他益处，这可能有助于增强健康和美容。
β-Glucans extracted from barley, which mainly contains β-(1,3-1,4)-D-glucan, are used extensively as supplements and food additives due to their wide biologic activities, including a reduction in blood lipid level. In this study, the antioxidant activity of β-glucan was examined to assess potential new benefits associated with β-glucan, because oxidative stress is considered one of the primary causal factors for various diseases and aging. β-Glucan extracted from barley was found to possess significant antioxidant activity. The amount of antioxidant activity was influenced by different physiologic properties (e.g., structure and molecular size) of β-glucan, which varied depending on the source and extraction method used. The antioxidant activity of β-glucan was significantly higher than that of various polymers that are used as food additives. These results indicate that β-glucan has promise as a polymeric excipient for supplement and food additive with antioxidant and other benefits, which may contribute to enhancing health and beauty.
