How to reduce the quality loss of aquatic products during storage is a topic worth exploring. This study proposed a method combining orthogonal dual-frequency ultrasound-assisted treatment (20 kHz vertically, 40 kHz horizontally, 400 W) with bioactive coating ( L. essential oil-carboxymethyl chitosan-locust bean gum) and discussed the effects of this combined treatment on the quality, lipid, and protein of large yellow croaker during cold storage (4 °C). The results showed that both ultrasound-assisted treatment (US) and bioactive coating (CMCS) significantly inhibited microbial growth and quality deterioration in the fish, with the combined treatment group (US+CMCS) showing the best effect. The shelf life of large yellow croaker in the control group (CK) was 6 d, while the shelf life for US, CMCS, and US+CMCS treatments was 12 d, 12 d, and 18 d, respectively. Additionally, the combined treatment inhibited lipid oxidation and effectively delayed the oxidative degradation of protein in the large yellow croaker during cold storage. Therefore, the method of orthogonal dual-frequency ultrasound-assisted treatment (20 kHz vertically, 40 kHz horizontally, 400 W) combined with bioactive coating ( L. essential oil-carboxymethyl chitosan-locust bean gum) proposed in this study was a promising approach for the preservation of aquatic products during storage.
如何减少水产品在储存过程中的品质损失是一个值得探索的课题。本研究提出了一种将正交双频超声辅助处理（垂直20kHz、水平40kHz、400W）与生物活性涂层（罗勒精油-羧甲基壳聚糖-刺槐豆胶）相结合的方法，并探讨了这种联合处理对大黄鱼在冷藏（4℃）期间品质、脂质和蛋白质的影响。结果表明，超声辅助处理（US）和生物活性涂层（CMCS）均能显著抑制鱼体中的微生物生长和品质劣变，联合处理组（US+CMCS）效果最佳。对照组（CK）大黄鱼的货架期为6天，而US、CMCS和US+CMCS处理组的货架期分别为12天、12天和18天。此外，联合处理抑制了脂质氧化，并有效延缓了冷藏期间大黄鱼蛋白质的氧化降解。因此，本研究提出的正交双频超声辅助处理（垂直20kHz、水平40kHz、400W）与生物活性涂层（罗勒精油-羧甲基壳聚糖-刺槐豆胶）相结合的方法是一种很有前景的水产品储存保鲜方法。
