摘　　要：以茶籽油为基油,以紫胶蜡和单甘酯为复合凝胶因子,采用直接法制备茶籽油凝胶,并对其持油性、硬度、结晶形成时间、热性质和流变性能等进行表征。结果表明:茶籽油凝胶的最佳制备工艺为紫胶蜡和单甘酯质量比1∶1、凝胶剂添加量11.6%(以茶籽油质量为基准)、加热温度81℃、加热时间22 min。在此工艺条件下,茶籽油凝胶持油性为98.88%±0.41%,硬度为(2.059±0.022)N。茶籽油凝胶的晶体形态、硬度和热力学性质与人造黄油性能相近。Camellia seed oil oleogel was prepared by direct method with camellia seed oil as base oil,shellac wax and monoglyceride as compound gelling agents,and the oil holding capacity,hardness,crystallization formation time,thermal properties and rheological properties of the prepared oleogel were characterized.The results showed that the optimal preparation process of camellia seed oil oleogel was mass ratio of shellac wax to monoglyceride 1∶1,addition amount of gelling agent 11.6%(based on the mass of camellia seed oil),heating temperature 81℃,and heating time 22 min.Under the conditions,the oil holding capacity of camellia seed oil oleogel was 98.88%±0.41%,and the hardness was(2.059±0.022)N.The crystal morphology,hardness and thermodynamic properties of the camellia seed oil oleogels were similar to those of commercial margarine.
