中文摘要：为研究养殖大黄鱼低温流通期间的鲜度品质变化,该文模拟了冷链与断链流通的温度条件,分析了流通过程中大黄鱼感官、色差、质构、挥发性盐基氮(total volatile basic nitrogen,TVB-N)值、K值及菌落总数等鲜度指标的变化趋势,并结合低场核磁共振技术综合评价了流通各阶段大黄鱼各状态水分含量变化及迁移规律。结果表明,随着流通时间的延长,大黄鱼的感官评分、L^(*)值呈下降趋势,色差b^(*)值、TVB-N值、K值和菌落总数则逐渐增大;与冷链组相比,断链组在流通过程中各鲜度指标变化更为显著(P<0.05)。低场核磁共振结果显示,断链组结合水稳定性下降更快,说明断链流通中温度波动对鱼肉结合水影响较大,且加速了样品鲜度品质劣变。结合水峰面积(A_(2b)+A_(21))与菌落总数、感官品质、色泽(L^(*)值和b^(*)值)、咀嚼性的指标呈显著相关,不易流动水峰面积(A_(22))和自由水峰面积(A_(23))均与TVB-N值和K值呈显著相关。该研究结果反映了冷链流通过程中大黄鱼因温度波动产生潜在的质量安全风险,同时为低场核磁共振技术在冷链物流过程中的产品品质监测上的应用提供参考。

外文摘要：To investigate the changes of freshness and quality of cultured Pseudosciaena crocea during low-temperature circulation,this paper simulated the temperature conditions of cold chain and broken chain circulation and analyzed the trends of freshness indicators,such as sensory,color difference,texture,total volatile basic nitrogen(TVB-N)value,K value,and the total bacterial colony of P.crocea during the circulation process.Results showed that the sensory score and L^(*)value of P.crocea decreased with the extension of circulation time,while the values of color difference b^(*),TVB-N,K,and total bacterial colony increased gradually.The freshness indexes changed more significantly in the broken chain group compared to the cold chain group(P<0.05).The results of low-field nuclear magnetic resonance(LF-NMR)showed that the bound water stability of the broken chain group decreased rapidly,indicating that temperature fluctuations in the broken chain circulation had a greater impact on the bound water of fish and accelerated the deterioration of freshness quality of samples.The peak area of bound water(A_(2b)+A_(21))was significantly correlated with the indicators of total bacterial colonization,organoleptic quality,color(L^(*)and b^(*)values),and chewiness,while the peak area of less mobile water(A_(22))and the peak area of free water(A_(23))were significantly correlated with the TVB-N and K values.Results reflect the potential quality and safety risks of P.crocea due to temperature fluctuations during cold chain distribution and provide a reference for the application of low-field NMR technology in monitoring product quality during cold chain logistics.
