    摘要:

    為延長南美白對蝦貯藏期,，對8種天然化合物的抑菌和南美白對蝦多酚氧化酶(PPO)抑制活性進行了對比試驗，發(fā)現(xiàn)肉桂醛同時兼具抑菌和抑制多酚氧化酶活性的雙重效果,。經(jīng)酶反應動力學分析,，證明肉桂醛是多酚氧化酶的非競爭性抑制劑,。采用正交試驗，對肉桂醛,、植酸和海藻酸鈉進行復配比較,，確定復合保鮮劑的最佳組分為：肉桂醛質(zhì)量分數(shù)0.10％、植酸質(zhì)量分數(shù)0.05％,、海藻酸鈉質(zhì)量分數(shù)0.50％,。復合保鮮劑處理可有效抑制蝦體菌落總數(shù)的增加和揮發(fā)性鹽基氮的積累,；同時還可抑制貯藏過程中的脂肪氧化，對感觀品質(zhì)具有良好的保持作用,，在(4±1)℃條件下貯藏期可達8~10d,，明顯提高了南美白對蝦貯藏過程中的品質(zhì)和貨架期。

    Abstract:

    The effects of eight natural compounds on quality and shelf life of Pacific white shrimps was investigated. Cinnamaldehyde exhibited both antimicrobial activity and inhibitory ability against polyphenol oxidase (PPO) activity to maintain the quality of the Pacific white shrimp during storage. The kinetic analysis showed that cinnamaldehyde was a noncompetitive inhibitor for PPO of the Pacific white shrimp. The combined preservative was optimized using orthogonal experiment and then the optimal combination was as follows: 0.10% cinnamaldehyde, 0.05% phytic acid and 0.50% sodium alginate. The aerobic plate counts (APC), total volatile bases nitrogen (TVB-N), thiobarbituric acid reactive substances (TBARS) assay and sensory analyses were used to investigate the change in the quality of the Pacific white shrimps after applications of different treatments. Based on these studies, shrimps treated with the combined preservative exhibited the lowest APC, TVB-N, and TBARS value among the all treatments by the end of storage. The combined preservative could improve the sensory properties and prolong the shelf life of the Pacific white shrimps to 8～10 days. 
