| 摘 要： | 为了探究冻结方式对中华管鞭虾(Solenocera melantho)肌肉差异蛋白质的影响,本试验运用非标记(label-free)定量蛋白质组学技术,研究液体浸渍冻结、真空包装结合浸渍冻结、静止空气冻结、真空包装结合空气冻结4种方式对中华管鞭虾差异蛋白表达的影响。结果表明,与新鲜中华管鞭虾相比,上述4种冻结方式处理后的虾肌肉中分别有269、162、299、289个差异蛋白,其中表达上调的蛋白分别有100、59、63、61个,表达下调的蛋白分别有169、103、236、228个。筛选出甘油-3-磷酸脱氢酶(NAD+)、β-胸腺素2个差异蛋白,有望成为与冻结中华管鞭虾品质变化相关的指示蛋白标志物。本研究为深入了解中华管鞭虾在不同冻结方式下的品质变化机制,以及寻找出与新鲜度相关的指示蛋白提供了理论依据,也为虾的冻结工艺技术提供了参考。

| Abstract: | In order to investigate the effect of freezing methods on muscular differential proteins of Solenocera melantho, the technology of label-free quantitative proteomics was used to study, the expression of differential proteins in Solenocera melantho treated by four freezing methods, including liquid immersion freezing, vacuum packaging combined with immersion freezing, still air freezing, and vacuum packaging combined with air freezing. The results showed that compared with fresh Solenocera melantho there were 269, 162, 299 and 289 differential proteins in shrimp muscles treated by four freezing methods, respectively. Among them, there were 100, 59, 63 and 61 proteins was up-regulated and 169, 103, 236 and 228 proteins was down-regulated. Two differential proteins, glycerol-3-phosphate dehydrogenase(NAD+) and thymosin beta, were screened to be the expected indicator protein markers related to frozen quality of Solenocera melantho. This study provides a theoretical basis for in-depth understanding of the quality change mechanism of Solenocera melantho under different freezing treatment and for finding indicator proteins related to freshness, and also provides a reference for the improving freezing process technology. |
