Abstract:

This study was carried out to explore the effect of high hydrostatic pressure (HHP) on quality changes
(microorganisms, enzymes and flavor components) of cultured yellow croaker. Through microbial analysis and enzymatic
characterization, it was found that HHP could inhibit bacterial growth and enzyme activities in yellow croaker. SPME
coupled with GC-MS was used to analyze the effect of HHP on the flavor components of yellow croaker. The results
indicated that the contents of flavor components, such as trimethylamine and indole, were (15.91 ± 1.02)% and (2.11 ±
0.23)%, respectively, without HHP after 12 days storage and they were reduced to (1.98 ± 0.02)% and 0, respectively, with
500 MPa HHP after 12 days.

Key words: Pseudosciaena crocea, high hydrostatic pressure, microorganisms, enzyme, flavor
