Active coating could improve the fish quality and extend the shelf life. This study investigates the effect of locust bean gum (LBG) and sodium alginate (SA) active coatings containing lemon verbena ( Kunth.) essential oil (LVEO) emulsions on microbiological, physicochemical and organoleptic evaluation of large yellow croaker () samples during refrigerated storage at 4°C. Results showed that LBG-SA coatings incorporated with 0.30 or 0.60% LVEO emulsions significantly inhibited the growth of mesophile bacteria, spp., HS-producing bacteria, lactic acid bacteria (LAB) and psychrophilic bacteria, and reduce the productions of trimethylamine (TMA), total volatile basic nitrogen (TVB-N) and ATP-related compounds. Further, the LVEO treatments also retarded the water migration and maintained the organoleptic evaluation results of large yellow croaker during storage at 4°C. In conclusion, the LBG-SA active coatings incorporated with LVEO emulsions maintained the quality and extended the shelf life of large yellow croaker during refrigerated storage.
活性涂层可以改善鱼肉品质并延长货架期。本研究考察了含有柠檬马鞭草（Kunth.）精油（LVEO）乳液的刺槐豆胶（LBG）和海藻酸钠（SA）活性涂层对大黄鱼（）样品在4°C冷藏储存期间的微生物、理化和感官评价的影响。结果表明，含有0.30%或0.60%LVEO乳液的LBG-SA涂层显著抑制了嗜温菌、 spp.、产HS菌、乳酸菌（LAB）和嗜冷菌的生长，并减少了三甲胺（TMA）、总挥发性盐基氮（TVB-N）和ATP相关化合物的产生。此外，LVEO处理还延缓了水分迁移，并在4°C储存期间保持了大黄鱼的感官评价结果。总之，含有LVEO乳液的LBG-SA活性涂层在冷藏储存期间保持了大黄鱼的品质并延长了其货架期。
