Pickering emulsion templating is a versatile technique in formulating highly networked oil-in-water emulsions applicable in foods, cosmetics, and pharmaceuticals areas. In this work, oleogels was prepared by oil-in-water Pickering emulsions using regenerated chitin (RCh) as the stabilizing particles. The effects of RCh concentrations (0.4/100-1.4 g/100 g) on the formation, rheology, and log-term stability of the emulsions and oleogles were investigated. It was found that the solid-like oloegel with a high concentration of liquid oil (>= 98 g/100 g) could be obtained after evaporating of water from the emulsions. Shear-thinning behavior was observed at lower concentrations of RCh (0.4-0.6 g/100 g) and higher frequencies in the emulsions. An increase in the viscoelastic property was achieved. Oleogels containing higher concentrations of RCh (0.8/100-1.4 g/100 g) showed excellent resistance against coalescence and Ostwald ripening during the storage time. These oleogels also showed good thermal stability (no sign of oil leakages) when heated to 80 degrees C for 2 days. This emulsion templating approach is a feasible oil structuring strategy promising to be used in various applications.
