摘要: 南极磷虾是地球上多细胞生物中生物量最大的单种生物资源之一。南极磷虾因其巨大的生物资源量及潜在的应用价值而受到广泛关注。本文以冷冻南极磷虾为原料,优化了南极磷虾蛋白质的提取条件。在单因素实验的基础上,通过响应面优化实验研究了离心时间、料液比、匀浆时间等对南极磷虾蛋白质得率的影响。结果表明,南极磷虾蛋白质较佳的提取条件为:碱溶阶段pH 11.5,酸沉阶段pH 5.5,离心温度4 ℃,离心转速10000 rpm,离心时间10 min,料液比1:3(w/v),匀浆时间3.0 min;在以上提取条件下的南极磷虾蛋白质得率为10.81%。

Abstract: As one of the largest biomass of multi-cellular animal species on earth,Antarctic krill (Euphausia superb) is paid more attention for its large biomass and potential value in recent years.To improve the extraction yield of Antarctic krill protein,Box-Behnken design was employed based on the single factor experiments.The independent variables,namely centrifugation temperature,solid-liquid ratio and homogenization time on the extraction yield of Antarctic krill protein were evaluated by response surface methodology (RSM).The results showed that the optimum conditions for extracting protein from Antarctic krill were as follows:pH value of alkali-dissolving stage 11.5,pH value of acid-precipitation stage 5.5,centrifugation temperature 4 ℃,centrifugation rate 10000 rpm,centrifugation time 10 min,solid-liquid ratio 1:3 (w/v),homogenization time 3 min.Under the optimum conditions,the extraction yield of Antarctic krill protein reached 10.81%.
