Description
Summary:The preparation and characterization of oleogels structured by using a combination of a surface‐active and a non‐surface‐active polysaccharide through an emulsion‐templated approach is reported. Specifically, the oleogels were prepared by first formulating a concentrated oil‐in‐water emulsion, stabilized with a combination of cellulose derivatives and xanthan gum, followed by the selective evaporation of the continuous water phase to drive the network formation, resulting in an oleogel with a unique microstructure and interesting rheological properties, including a high gel strength, G′>4000 Pa, shear sensitivity, good thixotropic recovery, and good thermostability. Well gel: Oleogels (containing >97 wt % liquid oil) are prepared by using a polysaccharide‐based emulsion as a template. The obtained oleogel has a unique microstructure and interesting rheological properties, including a high gel strength, shear sensitivity, good thixotropic recovery, and good thermostability.
