Abstract: A novel storage technique combining low-frequency electric field (LFEF) and ice temperature was applied to extend the shelf life of Pacific white shrimp ( Penaeus vannamei ). Changes in microbial community composition was investigated in Pacific white shrimp treated with LFEF in combination with ice temperature. LFEF treatment increased diversity of microbial communities and reduced abundance of major spoilage bacteria in Penaeus vannamei . The spoilage microorganisms of shripm samples stored at ice temperature for 11 days included Aliivibrio, Pseudoalteromonas, Photobacterium, Moritella and Psychrobacter . However, Pseudoalteromonas and Psychrobacter were dominant in LFEF-treated samples. Furthermore, due to the modulation of the microbial community by LFEF and ice temperature storage, the microbial structure in shrimp muscle did not tend to be simplistic. In conclusion, LFEF as an auxiliary technology for low temperature preservation is a reliable and potential method for preserving the quality of aquatic products.
