    摘要:

    研究了CO2-冷海水浸泡處理技術(shù)對南美白對蝦保鮮貯藏過程中品質(zhì)的影響,。研究結(jié)果表明， CO2-冷海水浸泡處理后蝦的菌落總數(shù),、大腸桿菌數(shù),、產(chǎn)H2S菌數(shù)和嗜冷菌數(shù)均比對照組低,。同時，貯藏期間揮發(fā)性鹽基氮（TVB-N）,、pH值和K值的增加也顯著低于對照組,。CO2-冷海水中貯藏8 d的蝦仍在二級鮮度范圍內(nèi)，其TVB-N為19.5mg /（100g）和K值為20.3%,，而對照組蝦已嚴(yán)重腐敗,。貯藏期間蝦肉的剪切力略有下降，但無顯著性差異,。CO2-冷海水處理能有效抑制蝦內(nèi)PPO的活性,，延緩蝦體的褐變和感官品質(zhì)的下降。

    Abstract:

    The combined effects of CO2 and cold seawater on the quality of Pacific white shrimp (Penaeus vanmamei) during the storage were investigated. The results showed that the total bacterial count (TBC), Escherichia coli count, H2S producing bacteria count and psychrophilic bacteria count of shrimp preserved in CO2-cold seawater (4℃) were lower than that of control group (samples were not in CO2-cold seawater but cold stroge). As a result, total volatile basic nitrogen (TVB-N), pH value and K value increased more slowly than that of control during storage. Shrimp in CO2-cold seawater was second-grade freshness (TVB-N value of 19.5mg/(100g), K value of 20.3%) after storage eight days comparing to serious spoilage of control. The shear force of shrimp flesh decreased slowly during storage, but there was no obvious difference. Activity of polyphenol-oxidase (PPO) was significantly inhibited by CO2-cold seawater. Meanwhile, melanosis of shrimp and deterioration of sense quality was delayed.
