| 摘 要： | 为分析电子束辐照处理对真空包装章鱼制品冷藏过程中生物胺形成的抑制作用,以真空包装的新鲜章鱼腕足段为研究对象,分别进行0、0.5、1.0、1.5、2.0和2.5 kGy剂量的电子束辐照处理,于4℃下冷藏63 d,每隔7 d进行感官品评和生物胺含量检测。结果表明,冷藏期间真空包装的章鱼中共检测出精胺、亚精胺、腐胺、尸胺、组胺和酪胺6种生物胺。电子束辐照处理能抑制章鱼冷藏过程中腐胺、尸胺、组胺和酪胺的生成,且抑制作用与辐照剂量成正比,其中对组胺生成的抑制效果最佳,仅在少数样品中被检出。此外,电子束辐照也抑制了章鱼中亚精胺和精胺在冷藏后期的分解。冷藏过程中的腐胺、尸胺和酪胺含量变化与样品感官品质表现出较好的一致性,高感官品质章鱼样品中的腐胺、尸胺和酪胺含量均≤10 mg·kg-1。综合电子束不同剂量辐照对章鱼感官品质和生物胺的抑制作用,1.0 kGy的电子束辐照剂量是真空包装章鱼4℃冷藏保鲜的最适前处理,其能延长高品质新鲜章鱼货架期至35 d。本研究结果为章鱼加工企业生产高品质章鱼产品提供了理论依据。

| Abstract: | The effects of low-dose electron beam irradiation on biogenic amines formation were studied to prolong the shelf-life of vacuum-packed octopus during storage.Vacuum-packed octopus were irradiated at doses of 0,0.5,1.0,1.5,2.0 and 2.5 kGy,respectively.Formation of biogenic amines and organoleptic properties were examined every 7th day during 63-day storage at 4℃.Six biogenic amines including putrescine,cadaverine,spermidine,spermine,histamine and tyramine were detected.Putrescine,cadaverine,histamine and tyramine were decreased proportional to the irradiation dose.And irradiation exhibits the best inhibitory effect on histamine,which only detected in a few sample.Besides,electron beam irradiation inhibited the degradation of polyamines spermidine and spermine at the later storage.The changes of putrescine,cadaverine and tyramine under irradiation were commendably consistent with the high sensory quality,which were all less than 10 mg·kg-1.Based on the effect of electron beam irradiation,1.0 kGy is the best dose on extensing the shelf life of high quality octopus to 35 days.The appropriate electron beam irradiation has a significant role for the industrial production of high quality octopus products. |
