摘要:

利用戊二醛修饰制备出了颗粒大小及油水浸润性适中的超氧化物歧化酶(SOD)纳米颗粒,并对改性SOD纳米颗粒进行扫描电镜(SEM)、浸润性、稳定乳液效果及酶活性表征。结果表明,改性后的SOD纳米颗粒具有颗粒大小均一、形貌规整、浸润性适中等特点,所制备的Pickering乳液能长时间保持稳定,且具有较好的抗氧化性能。

Abstract:

The SOD(superoxide dismutase) nanoparticles with good particle size and wettability were prepared by modification with glutaraldehyde. The modified SOD nanoparticles were characterized by scanning electron microscopy(SEM), contact angle, emulsion stability and enzyme activity. The results show that the modified SOD nanoparticles exhibit uniform particle size, regular morphology and good wettability. The Pickering emulsion stabilized by the modified SOD nanoparticles has high stability and antioxidation property.

Key words: SOD, nanoparticle, antioxidant, Pickering emulsion, cosmetics
