| 中文摘要: |
| 南极磷虾油（AKO）在 HLB 值为 6～16时具有较好的乳化能力，且在 HLB 值为8～11时表现最佳，倾向于形成水包油（O/W）型乳液。以南极磷虾油为乳化剂，鱼油为油相，制备O/W型乳液。研究了剪切速率、油相含量、AKO含量对乳液体系的影响，并利用单因素实验优化制备条件。结果表明:在南极磷虾油含量为3%，剪切速率为12 000 r/min，乳化时间为5 min，鱼油含量为60%条件下制备的乳液综合表现最好。 |
| 英文摘要: |
| 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%. |
