Abstract: 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%.

Key words: Antarctic krill, shrimp oil, extraction
