摘　　要：[Objectives]This study was conducted to investigate the optimal preparation conditions and storage stability of camellia oil-based gel oil.[Methods]With camellia oil as the base oil,rice bran wax and monoglyceride as gelling agents,a kind of composite gel oil was prepared by the direct gel method.The effects of different mass ratios of rice bran wax to monoglyceride,amounts of gelling agent,heating time and temperatures on the oil precipitation rate and hardness of gel oil were investigated.The optimal preparation conditions were determined by a response surface optimization experiment,and the storage stability of the prepared gel oil was studied with peroxide value and acid value as evaluation indexes.[Results]The results showed that the optimal preparation process of gel oil was as follows:mass ratio of rice bran wax to monoglyceride 2:8,addition amount of rice bran wax and monoglyceride 10%,heating temperature 95℃,and heating time 49 min.The peroxide value and acid value of composite gel oil stored at 4℃and room temperature for 5 weeks both showed an upward trend,and the acid value of gel oil differed significantly at different storage temperatures,which showed that the cold storage environment was more suitable for the gel oil.Compared with the gel oil prepared by single gelling agent,the camellia oil-based gel oil prepared by compounding rice bran wax and monoglyceride had lower oil precipitation rate and moderate hardness.[Conclusions]This study lays a theoretical foundation for developing new gel oil and expanding the application scope of camellia oil.
