ethyl-cellulose and sorbitan-monopalmitate

The current study developed ethylcellulose (EC) based oleogels with the addition of a surface active ingredient (sorbitan monopalmitate, SP), in order to increase the active loading of curcumin by reducing lipid oxidation, improving curcumin solubility and chemical stability. With the increase in SP content, EC oleogels had more compact gel networks with evenly distributed smaller pores. Rheological analysis revealed that the gels had shear-thinning behavior, and higher concentration of SP contributed to the systems with higher viscosity. The inclusion of SP also worked to reinforce gel strength as determined by frequency sweep, creep recovery and textural analyses. EC oleogels with higher content of SP were capable to hold more liquid oil during centrifugation, and the T
