中文摘要: 为探究冷冻贮藏期间烤鱼品质的变化,考察-18 ℃冻藏过程中冷冻烤鱼的色泽、质构、持水力、水分分布、硫代巴比妥酸(thiobarbituric acid reaction substances,TBARS)含量、挥发性盐基氮(total volatile base-nitrogen,TVB-N)含量、感官评分的变化。结果表明,冷冻贮藏期间,随冻藏时间的延长,烤鱼产品的硬度、咀嚼度分别由30 d 时的461.32、343.15 g 降至210 d 时的204.66、134.71 g,感官评分由45.37 降至24.73,烤鱼内部水分流动性受限,导致持水力不断降低;而a*值、b*值、TBARS 含量、TVB-N 含量呈增加趋势,TVB-N 含量从3.57 mg/100 g 增加至23.10 mg/100 g,在第196天时,TVB-N 含量达到国家标准中的最大限量(20 mg/100 g)。因此,冻藏过程中烤鱼品质不断劣变,在冻藏196 d 后烤鱼品质劣变严重,不宜继续冷冻贮藏及食用。
Abstract:The aim of this study was to investigate the changes in the quality of roasted fish during frozen storage.The color,texture,water holding capacity,water distribution,thiobarbituric acid reaction substances(TBARS)content,total volatile base-nitrogen(TVB-N)content,sensory scores of frozen roasted fish were examined during freezing at -18 ℃.The results showed that during the frozen storage period,as the storage time increased,the hardness and chewiness of the roasted fish products decreased from 461.32 and 343.15 g at 30 d to 204.66 and 134.71 g at 210 d,respectively,and the sensory score decreased from 45.37 to 24.73.The movement of water within the roasted fish was restricted,leading to a continuous decrease in water holding capacity.Moreover,the a* value,b* value,TBA content,and TVB-N content demonstrated an increasing trend.The TVB-N content increased from 3.57 mg/100 g to 23.10 mg/100 g,reaching the maximum allowable limit(20 mg/100 g)according to national standards on the 196th day.Therefore,the quality of roasted fish deteriorated continuously during the freezing process,and after 196 d of freezing,the quality of roasted fish deteriorated seriously,which made it unsuitable for further frozen storage and consumption.
