| 摘 要： | 为解决南美白对虾易腐易黑变问题,延长其货架期,通过响应面优化方法,利用植酸、壳聚糖和ε-聚赖氨酸进行复配。结果表明,该复配保鲜剂最佳配比为植酸0.07%;壳聚糖1.5%;ε-聚赖氨酸0.1%(质量分数)。利用该保鲜剂处理南美白对虾,在(4±1)℃条件下,通过对虾体进行感官、pH值、挥发性盐基氮(total volatile base nitrogen,TVB-N)、菌落总数和三甲胺(trimethylamine,TMA)指标的测定,表明了复合保鲜剂能够有效地保持南美白对虾的品质,使南美白对虾在(4±1)℃的货架期由原来的3～4d延长至7～8d,细菌总数在第10天才达到5.7lg(CFU/g),为生物保鲜剂的优化及南美白对虾保鲜技术的推广提供一定的技术支持。

| Abstract: | In order to keep Penaeus Vanmamei fresh,restrain melanosis and extend its shelf-life,response surface method(RSM) was used in the experiments to get a complex preservative combined with phytic acid,chitosan and ε-polylysine.Results showed that the best combination of the complex preservative was that of phytic acid 0.07%,chitosan 1.5% and ε-polylysine 0.1%.By treatment with the combined preservative,the sensory evaluation,pH value,total volatile basic nitrogen(TVB-N),total bacteria count(TBC) and trimethylamine(TMA) of Penaeus vannamei were determined under the storage of(4±1)℃ to evaluate the quality of samples.It was found that the combined preservative could keep a better sensory quality,and the shelf-life under the storage of(4±1)℃ was prolonged from 3-4 to 7-8 days.The total bacterial count(TBC) was only 5.7 lg(CFU/g) on the 10th day.The conclusions can provide a technical support for the optimization of natural preservative and extension of preservation of Penaeus Vanmamei. |
