Preparation and characterization of nanoemulsions of grape seed polyphenol-loaded camellia oil
摘要
Abstract
[Objective]To develop a highly stable camellia oil nanoemulsion system for loading grape seed polyphenol(GSP)to enhance its antioxidant property and solubility stability.[Methods]The formula is optimized based on the pseudo-ternary phase diagram method(moil phase∶msurfactant phase=8∶2,mTween 80∶mSpan 80=5∶5,absolute ethanol is used as the cosurfactant,and Km=4).The emulsion stability and water distribution are characterized by Zeta potential and low-field nuclear magnetic resonance,and its antioxidant activity is evaluated.[Results]The obtained W/O nanoemulsion has a particle size of(326.5±2.7)nm,an absolute value of Zeta potential of(46.4±0.2)mV,a polydispersity index(PDI)of 0.238,and an electrical conductivity of 4.8 μS/cm.When loaded with 1.5%GSP,the proportion of free water decreases to 17.21%,and the scavenging rates of DPPH free radicals and ABTS free radicals are 82.69%and 71.18%,respectively.After centrifugation(10 000 r/min),high temperature(90℃),low temperature(-4℃)and 30-day storage,there is no stratification,and the light transmittance is>95.8%.[Conclusion]This system combines high biological activity retention with long-lasting stability.关键词
