摘　　要：为探究β-环糊精(β-CD)与酪蛋白酸钠(SC)对南极磷虾油Pickering乳液的协同稳定效果,分别采用β-CD、SC和β-CD/SC复合物为稳定剂,制备南极磷虾油Pickering乳液。以乳液的宏观和微观形貌变化、粒径、ζ-电位和黏度为特征指标,对乳液进行表征。结果表明:β-CD/SC复合物制备的乳液具有更小的粒径(13.66μm)、更高的ζ-电位绝对值(31.90 mV)以及更高的黏度。比较离心处理、热处理以及冻融处理前、后乳液特征指标的变化,评价不同稳定剂制备的南极磷虾油Pickering乳液的稳定性,结果表明,β-CD/SC复合物制备的乳液具有更好的总体稳定性。β-CD与SC复合物对南极磷虾油Pickering乳液具有协同稳定作用,在乳液领域具有显著的应用潜力。To investigate the synergistic stabilization effect ofβ-cyclodextrin(β-CD)and sodium caseinate(SC)on Antarctic krill oil Pickering emulsion.In this paper,Antarctic krill oil Pickering emulsions were stabilized byβ-CD,SC andβ-CD/SC complexes,respectively.The Pickering emulsions were characterized by macroscopic and microscopic morphological changes,particle size,ζ-potential,and viscosity.The results showed that the emulsion stabilized byβ-CD/SC complex had the smallest particle size(13.66μm),highest absolute value ofζ-potential(31.90 mV),and strongest viscosity.In addition,the stability of Antarctic krill oil Pickering emulsions stabilized by different stabilizers was evaluated by centrifugation treatment,thermal treatment,and freeze-thaw treatment.The results showed that the emulsion prepared byβ-CD/SC complexes possessed the best overall stability.The complex ofβ-CD and SC had a significant synergistic stabilization effect on Antarctic krill oil Pickering emulsion and had remarkable potential for application in the emulsion field.
