| Abstract: |
| Antarctic krill oil (AKO) has a good emulsifying ability when the HLB value is between 6 and 16, and especially at the HLB value ranging from 8 to 11，it tends to form an oil-in-water (O/W) emulsion. The O/W emulsion was prepared by using AKO as an emulsifier and fish oil (FO) as an oil phase. The effects of shear rate, oil phase concentration and AKO concentration on the emulsion system were studied and single-factor experiments were performed to optimize the preparation conditions. The results showed that the O/W emulsion exhibited best comprehensive performace under the preparation conditions of the AKO concentration of 3%, the shear rate of 12 000 r/min, the emulsification time of 5 min, and the FO phase concentration of 60%. |
