| Abstract: | Alkaline solubilization and acid precipitation method was employed to extract proteins from whole Antarctic krill(Euphausia superba),and effect of transglutaminase on protein recovery yield was researched.Results indicated that the alkaline solubilization and acid precipitation method was good at recovering protein from whole Antarctic krill,and protein recovery yield was increased by approximate 5%,when transglutaminase was correctly applied during acid-induced protein precipitation. |

| Keywords: | Antarctic krill protein yield alkaline solubilization and acid precipitation method transglutaminase |
