摘要
研究南极磷虾粗虾油的有机溶剂提取工艺。探讨不同提取剂、提取剂混合比、提取时间、提取温度和料液比对南极磷虾粗虾油得率的影响。在单因素试验基础上,通过响应面分析确定最佳的提取工艺条件为:以正己烷+乙酸乙酯为提取剂,提取剂混合比71.3:28.7、料液比1:6.6,在57.8℃提取50min;此时粗虾油得率为14.76%。
A method to extract shrimp oil from Antarctic krill by organic solvent extraction was developed and optimized.Oil yield was investigated with respect to extraction parameters such as solvent type,mixed solvent composition,extraction time,temperature and solid-to-liquid ratio.One-factor-at-a-time experiments followed by response surface analysis was carried out to achieve the optimal extraction conditions below： a mixture of n-hexane and ethyl acetate at a ratio of 71.3：28.7 as solvent,solid-to-liquid ratio 1：6.6,and temperature 57.8 ℃ for an extraction time of 50 min.under these conditions,the yield of Antarctic krill oil was 14.76%.
