In this study, the microbiological, physicochemical, and flavor changes of turbot (Scophthalmus maximus) coated with a composite active coating of locust bean gum (LBG) and sodium alginate (SA) supplemented with daphnetin emulsions (0.16, 0.32, 0.64 mg·mL) were determined during 18 days of refrigerated storage (4 ± 1 °C). Results showed that LBG-SA coatings containing 0.32 mg·mL daphnetin emulsions could significantly lower the total viable count (TVC), psychrophiles, Pseudomonas spp. and HS-producing bacteria counts, and inhibit the productions of off-flavor compounds including the total volatile basic nitrogen (TVB-N), trimethylamine (TMA) and ATP-related compounds. 32 volatile compounds were identified by solid phase microextraction combined with gas chromatography-mass spectrometer method (SPME-GC/MS) during refrigerated storage and the treated turbot samples significantly lowered the relative content of fishy flavor compounds. Further, the LBG-SA coatings containing daphnetin could also delay the myofibril degradation of the turbot samples. These results indicated that the LBG-SA coatings with 0.32 mg·mL daphnetin were a potential alternative way to improve the quality of turbot during refrigerated storage.
在这项研究中，研究了在冷藏（4±1°C）期间，添加了瑞香素乳液（0.16、0.32、0.64mg·mL）的槐豆胶（LBG）和海藻酸钠（SA）复合活性涂层对牙鲆（Scophthalmus maximus）的微生物学、物理化学和风味变化。结果表明，含有 0.32mg·mL 瑞香素乳液的 LBG-SA 涂层可以显著降低总活菌数（TVC）、嗜冷菌、假单胞菌和产 HS 细菌的数量，并抑制包括总挥发性碱性氮（TVB-N）、三甲胺（TMA）和 ATP 相关化合物在内的异味化合物的产生。通过固相微萃取结合气相色谱-质谱联用（SPME-GC/MS）在冷藏期间鉴定了 32 种挥发性化合物，经处理的牙鲆样品显著降低了腥味化合物的相对含量。此外，含有瑞香素的 LBG-SA 涂层还可以延缓牙鲆样品肌原纤维的降解。这些结果表明，含有 0.32mg·mL 瑞香素的 LBG-SA 涂层是一种在冷藏期间改善牙鲆品质的潜在替代方法。
