Bigeye tuna () is an economically valuable ocean fish species. It is susceptible to contamination during storage and transportation. Having proper transportation packaging and stable temperature during transportation are critical to prevent quality deterioration. However, the influence of packaging on retaining freshness in transit remains unknown. Here, the impact of different transportation packaging on the quality and microbiological variation of bigeye tuna during the logistics process was investigated by measuring physical-chemical indexes and microbial diversity. It turned out that aluminum foil paper (AFP) group had minimum temperature fluctuation, exhibited preferable water retaining capacity and color protection effect. AFP packaging could efficiently prevent TVB-N increase and microbial growth. After 40 h, the TVB-N value was 21.28 mg/100 g and microbial total plate count was 3.53 lg CFU/g, which was within the acceptable range. Temperature fluctuations and packaging materials had a major effect on the microbial community structure of bigeye tuna. , and were dominant in the AFP group, while , and were dominant in the expanded polystyrene foam (EPSF) and European logistics (EUL) groups. AFP packaging could effectively slow down the growth and reproduction of , restraining the growth of microorganisms and preserve the quality of bigeye tuna. This study provides insights into understanding the effects of packaging material on maintaining quality during logistics transportation.
大眼金枪鱼（ ）是一种具有经济价值的海洋鱼类。它在储存和运输过程中容易受到污染。在运输过程中采用合适的运输包装并保持稳定的温度对于防止品质恶化至关重要。然而，包装对运输过程中保持新鲜度的影响尚不清楚。在此，通过测量理化指标和微生物多样性，研究了不同运输包装对大眼金枪鱼物流过程中品质和微生物变化的影响。结果表明，铝箔纸（AFP）组温度波动最小，具有较好的保水能力和护色效果。AFP包装能有效防止TVB-N值升高和微生物生长。40小时后，TVB-N值为21.28mg/100g，微生物总平板计数为3.53lg CFU/g，在可接受范围内。温度波动和包装材料对大眼金枪鱼的微生物群落结构有重大影响。AFP组中 、 和 占主导地位，而在发泡聚苯乙烯泡沫（EPSF）和欧洲物流（EUL）组中 、 和 占主导地位。AFP包装能有效减缓 的生长繁殖，抑制微生物生长，保持大眼金枪鱼的品质。本研究为理解包装材料在物流运输过程中对保持品质的影响提供了见解。
