摘要:

以养殖大黄鱼为研究对象,研究超高压作用对养殖大黄鱼鱼肉中的微生物、酶和风味组分的影响。结果表明:在超高压作用下降低了鱼肉组织中酶的活力:超高压对微生物有杀灭和抑制效果;通过固相微苹取技术(SPME)及气相色谱-质谱联用法(GC-MS)分析贮藏过程中超高压处理对养殖大黄鱼风味组分的影响表明:无超高压作用下贮藏12d后养殖大黄鱼主要腥臭物质三甲胺和吲哚等的含量分别为(15.91±1.02)%和(2.11±0.23)%,但在贮藏12d后,超高压(500MPa)处理后的大黄鱼中主要腥臭物质三甲胺和吲哚等的含量为(1.98±0.02)%和0。

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
