Abstract: In order to improve the storage properties and increase shelf life of Antarctic krill meal, the effect of adding deoxidant ( iron powder) on the storage properties of Antarctic krill meal was studied.Results showed that compared with the Antarctic krill meal not adding deoxidant, sensory score of the Antarctic krill meal adding deoxidant could be reduced from 1.21 to 0.93, the acid value was decreased from 2.29mg /kg to 2.00mg /kg at 35℃ after 165d.In the process of storage, adding deoxidant could slow down the speed of krill meal color changes, TBARS values of adding deoxidant group were lower than that of the control group.But during the storage time the study involved, the influence of adding deoxidant on pepsin digestibility was not obvious. Comprehensive determination results of each quality index, adding deoxidant could effectively inhibit oil rancidity, slow down the speed of color change and obviously improve the properties of the Antarctic krill meal storage.The study showed that adding deoxidant could serve as a simple and effective method for preserving the Antarctic krill meal.
