摘　　要：为了验证复合生物保鲜剂对冷藏红鳍东方鲀的保鲜效果,本实验选择水浓度为0.68%的柠檬酸、1.45%的百里酚以及1.94%的海藻酸钠的复合生物保鲜剂处理红鳍东方鲀,将其贮藏在冷藏(4±1)℃条件下,并设置未经保鲜剂处理的鱼肉为对照组,以pH、挥发性盐基氮(TVB-N)、硫代巴比妥酸值(TBA)、菌落总数、假单胞菌数及汁液流失率为指标,评价复合生物保鲜剂的保鲜效果。结果表明:保鲜组可以显著减缓pH和TVB-N值的上升,延缓鱼肉的氧化,抑制菌落总数和假单胞菌属的生长繁殖,贮藏12 d时接近食用上限。对照组在贮藏6d时已腐败变质,货架期大约在5d左右;保鲜组在贮藏12d时汁液流失率为1.63%,与对照组贮藏6d时无差异(p>0.05)(1.63%),显著低于气调保鲜法的汁液流失率。结论:综合各指标的测定,复合生物保鲜剂对冷藏红鳍东方鲀保鲜效果显著,可以将货架期由5d延长至12d左右。In order to verify the preservation effect of the complex biological preservatives on the Takifugu rubripes during cold storage, the experiment selected complex biological preservatives made by 0.68% citric acid, 1.45% thymol and 1.94% sodium alginate to deal with Takifugu rubripes stored under the condition of（4±1 ） ℃ .The pH value ,TVB-N ,TBA ,total plate counts, pseudomonas sp counts and drip loss were investigated as an indicator to evaluate the preservation effect of composite biological preservatives.The result showed that the complex biological preservatives treatment could delay the rise of pH and TVB- N value, and slow down the oxidation of fish, and inhibit the total plate counts and Pseudomonas reproduction. The untreated control samples had been corrupted and deteriorated on the 6th day of storage, and the shelf life was about 5 days.As well as the drip loss was 1.63% significantly lower than modified atmosphere preservation on the 12th day of storage（p 〉 0.05 ） ,which had no significant difference with untreated control samples stored for 6 days.The conclusion was that the complex bio-preservatives had a significant effect on refrigerated Takifugu rubripes, which could extend the shelf life of the Takifugu rubripes from 5 d to about 12 d.
