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
