The purpose of this research was to explore the fresh keeping effect of modified atmosphere packaging (MAP) with different gas ratios combined with gelatin active coatings containing eugenol on Chinese sea bass stored at -0.9 °C for 36 days. The results showed that MAP3 (60% CO/10% O/30% N), together with gelatin active coatings containing eugenol, could prevent water loss, which maintained high field NMR, MRI, and organoleptic evaluation results. This hurdle technology could also effectively delay the bacterial reproduction, protein degradation, and alkaline accumulation, so it showed the lowest K value, total volatile basic nitrogen, free amino acids, total viable count, spp., and HS-producing bacteria, which better maintain the quality of sea bass.
本研究旨在探索不同气体比例的改良气氛包装（MAP）与含丁香酚的明胶活性涂层相结合对中国鲈鱼在-0.9°C下冷藏 36 天的保鲜效果。结果表明，MAP3（60% CO/10% O/30% N）与含丁香酚的明胶活性涂层相结合，可以防止水分流失，保持高场 NMR、MRI 和感官评价结果。这种障碍技术还可以有效抑制细菌繁殖、蛋白质降解和碱性物质积累，因此表现出最低的 K 值、总挥发性碱性氮、游离氨基酸、总活菌数、 spp. 和产 HS 细菌，更好地保持鲈鱼的质量。
