| 中文摘要: |
| 以五步蛇蛇油为基料油，通过向其添加不同质量比的蜂蜡与单甘酯制备凝胶油。探讨不同蜂蜡与单甘酯的质量比对五步蛇蛇油基凝胶油流变性、持油性以及硬度的影响，并对其结晶型态、结晶形状进行分析。结果表明：少量单甘酯的存在（蜂蜡与单甘酯质量比8∶?2）降低了五步蛇蛇油基凝胶油的黏度恢复值及硬度，促进凝胶油长枝状结晶的生成，增加α、β以及β′型晶体；随着单甘酯比例的进一步增加（蜂蜡与单甘酯质量比8∶?2~0∶?10），五步蛇蛇油基凝胶油析油率和黏度恢复值增加，长枝状结晶逐渐变短至消失，α型晶体逐渐消失；确定蜂蜡与单甘酯质量比4∶?6为最佳比例，此时五步蛇蛇油基凝胶油的析油率为1.8%，硬度为242 g，黏度恢复值为37%。 |
| 英文摘要: |
| The composite organogels were prepared from refined snake (deinagkistrodon acutus) oil added with beeswax and monoglyceride. The effect of mass ratio of beeswax to monoglyceride on the rheological properties, oil-binding capacity, hardness and crystallization behavior were studied. The results showed that the presence of a small amount of monoglyceride (mass ratio of beeswax to monoglyceride 8∶?2) could promote the generation of gel-like dendritic crystals, increase the number of crystals of α, β and β′, but reduce viscosity recovery value and hardness. As the content of monoglyceride increased (mass ratio of beeswax to monoglyceride 8∶?2-0∶?10), the elongated dendritic crystals gradually shorten to disappear, and α crystal gradually disappeared, but the viscosity recovery value and oil evolution rate increased. The optimal mass ratio of beeswax to monoglyceride was 4∶?6, at this time, the oil evolution rate, hardness and viscosity recovery value of snake oil organogel were 1.8%, 242 g and 37% respectively. |
