| 摘 要： | 为探索伽马辐照对淡腌大黄鱼的保鲜效果,以感官、菌落总数(TVC)、总挥发性盐基氮(TVB-N)和硫代巴比妥酸反应产物(TBARS)为指标,探讨1kGy低剂量辐照对常温(25℃)贮藏淡腌大黄鱼品质和货架期的影响。结果表明,低剂量辐照处理可延长淡腌大黄鱼的货架期,对照组货架期分别为9和11d,而试验组的货架期可分别延长至16和20d;辐照处理后淡腌大黄鱼的菌落总数显著减少,在贮藏期间试验组数量始终比对照组少;辐照处理可显著减缓淡腌大黄鱼挥发性盐基氮的增加;对脂肪氧化的影响较小。研究结果为海产品辐照商业化应用提供了技术依据。

| Abstract: | To explore the preservation effect of γ irradiation on light salted Pseudosciaena crocea,the influence of 1kGy low-dose γ irradiation on sensory quality,microbiological and chemical quality including TVC,TVB-N and TBARS contents of light salted P.crocea stored at 25℃ was discussed.The results showed that the number of total viable counts significantly decreased after irradiation,during the whole storage,the bacteria numbers of light salted P.crocea treated with irradiation were still less than the control.The concentrations of TVB-N was significantly reduced after irradiation,whereas lipid oxidation was less accelerated.The shelf life could be remarkably prolonged after low-dose γ irradiation.While the shelf life of control group were 9 and 11 days,the shelf life of irradiated light salted P.crocea were extended to 16 and 20 days,respectively.The results can provide technical references for commercial application of seafood irradiation. |
