| Abstract: |
| Antarctic krill oil is an important product extracted from Antarctic krill (Euphausia superba). As an emerging functional marine lipid, krill oil has a broad market prospect. The production methods of Antarctic krill oil were firstly summarized. Then the types of proteases, raw materials and oil extraction methods from enzymatic hydrolysis solution in the extraction of Antarctic krill oil by enzymatic hydrolysis process were reviewed. The comprehensive utilization of by-products in the enzymatic hydrolysis process was also described. The enzymatic extraction of Antarctic krill oil had disadvantages such as high price of enzyme and the existence of emulsification layer betweern the water phase and oil phase after enzymolysis. However, the enzymatic extraction method could not only obtain high-quality Antarctic krill oil, but also the enzymatic hydrolysis by-products after defatting could be further utilized, and the high-value utilization of Antarctic krill could be realized. |
