| Abstract: |
| In order to explore the potential of linseed oil-based oleogel as a substitute for traditional plastic fat, using rice bran wax as the gelling agent, the effects of different rice bran wax addition on the appearance, microstructure, oil holding rate, physicochemical properties and thermodynamic properties of linseed oil-based oleogel were investigated. The results showed that at room temperature, linseed oil would be gelled when the addition of rice bran wax was not less than 6%. With the increase of rice bran wax addition, the crystal network structure of oleogel gradually changed from cluster to needle, and the crystal density increased. The oil holding rate, acid value and peak temperature of melting peak/crystallization peak of oleogel increased with the increase of rice bran wax addition. The peroxide value of oleogel increased first and then decreased with the increase of rice bran wax addition. In conclusion, adding appropriate amount of rice bran wax to linseed oil can form an oleogel with good thermoplasticity, stable structure, good physicochemical properties and high oil holding rate. |
