摘　　要：以花生油为基料油,利用9c,11t-共轭亚油酸酯化改性白藜芦醇,并与蜂蜡复配制备白藜芦醇共轭亚油酸酯凝胶油,探讨蜂蜡与白藜芦醇共轭亚油酸酯添加量、蜂蜡与白藜芦醇共轭亚油酸酯质量比、加热温度、加热时间和冷却温度对白藜芦醇共轭亚油酸酯凝胶油持油性的影响,并对其基本理化性能、热性能、组成成分进行表征。结果表明:蜂蜡与白藜芦醇共轭亚油酸酯添加量12%、蜂蜡与白藜芦醇共轭亚油酸酯质量比7∶3、加热温度70℃、加热时间20 min、冷却温度4℃,白藜芦醇共轭亚油酸酯凝胶油的持油性最高可达98.6%;与蜂蜡凝胶油相比黏度降低30%、亮度降低、减少了α型晶体,并发现白藜芦醇共轭亚油酸酯凝胶油无反式脂肪酸生成。Resveratrol was esterified by 9c,11t-conjugated linoleic acid(CLA), and complexed with beeswax to prepare oleogel rich in resveratrol conjugated linoleate using peanut oil as the base oil. The effects of the concentration of beeswaxresveratrol conjugated linoleate mixture(BRE), mass ratio between beeswax and resveratrol conjugated linoleate, heating temperature, heating time and cooling temperature on the oil retention capacity of oleogel rich in resveratrol conjugated linoleate were discussed, and its basic physicochemical properties, thermal properties, and composition were characterized.The results showed that the preparation conditions that provided maximum oil retention capacity(98.6%) were determined as 12%, 7:3, 70 ℃, 20 min and 4 ℃ for BRE concentration, mass ratio of beeswax to resveratrol conjugated linoleate,heating temperature, heating time and cooling temperature, respectively. Compared with beeswax oleogel, the viscosity of the obtained product was reduced by 30%, and the brightness and the α-type crystals were also reduced. Furthermore, it was found that oleogel rich in resveratrol conjugated linoleate had no trans fatty acid.
