Abstract

ABSTRACT High pressure processing (HPP) and sous vide may increase the shelf-life of high value seafood products without the use of additives. This study investigated the effects of 150MPa or 350MPa for 10min on microbial, sensory, and physicochemical qualities of raw and subsequently sous vide cooked (65°C) lobster tails during 28 days of refrigerated storage. Raw lobster pressurized at 350MPa or sous vide cooked maintained significantly lower microbial counts, total volatile base nitrogen, and biogenic amine levels. Due to off-odors, 90% and 60% of sensory respondents rejected the control and 150MPa raw samples, respectively, by day 7, while 70% rated the 350MPa samples as still acceptable on day 28. For cooked lobster, only 20% of the respondents rejected any samples by day 28. Moderate HPP conditions were effective in extending refrigerated shelf-life of vacuum-packaged raw lobster tails. However, HPP pretreatment did not contribute to additional shelf-life extension for sous vide cooked products.

高压加工龙虾、生龙虾和生龙虾的冷藏保质期评估

摘要高压加工（HPP）和真空处理可以在不使用添加剂的情况下延长高价值海鲜产品的保质期。本研究调查了在冷藏28天期间，150MPa或350MPa持续10分钟对生龙虾尾和随后经冷藏（65°C）的龙虾尾的微生物、感官和理化性质的影响。生龙虾在350MPa的压力下加压或真空烹饪，可以显著降低微生物计数、总挥发性碱氮和生物胺水平。由于异味，90%和60%的感官受访者在第7天分别拒绝了对照和150MPa的原始样本，而70%的人在第28天认为350MPa的样本仍然可以接受。对于煮熟的龙虾，只有20%的受访者在第28天拒绝接受任何样本。适度的HPP条件有效地延长了真空包装生龙虾尾的冷藏保质期。然而，HPP预处理并没有延长冷藏产品的保质期。
