摘要:

目的:研究复合保鲜剂结合冰温贮藏对南美白对虾的保鲜作用,避免其腐败变质,从而延长其货架期。方法:将复合生物保鲜剂处理过的南美白对虾贮藏在不同温度(4 ℃和-2.2~-1 ℃)条件下,通过pH值、感官评分、菌落总数、挥发性盐基氮含量、Ca2+-ATP酶比活力和硫代巴比妥酸含量指标的测定,对实验结果进行方差分析,确定最佳保鲜贮藏组合。结果:复合生物保鲜剂结合冰温贮藏延长了南美白对虾的货架期。结论:复合生物保鲜剂结合冰温贮藏对南美白对虾保鲜效果更佳,能使南美白对虾货架期达到21 d。

Abstract:

Objective: To explore the effect of composite biological preservative combined with ice temperature storage on
preventing deterioration and prolonging the shelf-life of Penaeus vannamei. Methods: Penaeus vannamei were treated with
a composite biological preservative consisting of nano-TiO2, chitosan, lysozyme, and propolis and then stored at different
temperatures. pH, sensory evaluation, total plate count, TVB-N value, Ca2+-ATPase activity, and TBA value were measured
during storage periods, and the experimental data were analyzed by analysis of variance. Results: The composite biological
preservative combined with ice temperature storage could prolong the shelf-life of Penaeus vannamei. Conclusion: The
shelf-life of Penaeus vannamei stored at ice temperature can be prolonged to 21 days by treatment with the composite
biological preservative.

Key words: Penaeus vannamei, composite biological preservative, ice temperature storage, preservation
