| Abstract: |
| Candelilla wax(CLW) and Japan lacquer wax(RLW) were added into high-oleic sunflower seed oil to prepare oleogels, and the difference in crystalline behavior during the formation of oleogels was analyzed. The results showed that both the waxes exhibited stable oleogels with low frequency dependence at the dosage of 5%. Candelilla wax had stronger thermal stability and apparent viscosity, while Japan lacquer wax had higher thixotropic recovery. Thermal properties further comfirmed that the difference of oleogels capacity was related to the composition of waxes. At the microscopic level, candelilla wax oleogels and Japan lacquer wax oleogels presented cluster and needle-like crystal morphologies, respectively. The crystal polymorph of candelilla wax was β′, while the crystal arrangement of Japan lacquer wax changed in the process of forming oleogel, and its crystal polymorph turned from β′ to β. Japan lacquer wax had special crystalline properties different from other high-melting point waxes, and had potential application value in the development of plastic fat replacement |
