ABSTRACT A new method to stabilize ferulic acid (FA) in the aqueous phase by encapsulating FA into β-cyclodextrin was developed to prepare ferulic acid-β-cyclodextrin inclusion complexes (FCICs), and the potential applications of FCIC as a preservative in hairtail (Trichiurus lepturus) were tested. The antibacterial properties of specific spoilage bacteria in hairtail were analyzed. FCIC possessed significantly higher efficacy (p < .05) of scavenging DPPH and H2O2 radicals. In the antibacterial assessment, several strains isolated from hairtail after ten days of storage were selected. FCIC showed significantly higher antibacterial activities (p < .05) against these bacteria. To further validate whether the antioxidant and antibacterial activities of hairtail remained throughout storage, the physiological properties of hairtail were analyzed. It was shown that hairtailtreatment with FCIC inhibited the spoilage of hairtail throughout storage at 4°C. FCIC with an FA:β-CD ratio of 1:2 (IC1:2) could prolong the shelf life of refrigerated hairtail for 3–5 days. This study provided an enormous potential for applying FA in the shelf-life extension of hairtail.

阿魏酸-β-环糊精包合物：在带鱼保存中的应用（Trichiurus lepturus）

摘要 开发了一种通过将 FA 包裹在 β-环糊精中来稳定水相中阿魏酸 (FA) 的新方法来制备阿魏酸-β-环糊精包合物 (FCICs)，以及 FCIC 作为带鱼防腐剂的潜在应用。 Trichiurus lepturus) 进行了测试。分析了带鱼中特定腐败菌的抗菌特性。FCIC 具有明显更高的清除 DPPH 和 H2O2 自由基的功效 (p < .05)。在抗菌评估中，选择了储存十天后从带鱼中分离的几种菌株。FCIC 对这些细菌显示出显着更高的抗菌活性 (p < .05)。为了进一步验证带鱼的抗氧化和抗菌活性是否在整个储存过程中保持不变，对带鱼的生理特性进行了分析。结果表明，在 4°C 的整个储存过程中，用 FCIC 处理的带鱼抑制了带鱼的腐败。FA:β-CD 比例为 1:2 (IC1:2) 的 FCIC 可以延长冷藏带鱼的保质期 3-5 天。这项研究为将 FA 应用于带鱼保质期延长提供了巨大的潜力。
