| 中文摘要: |
| 以油茶籽油为基料油，通过添加单甘酯与蜂蜡制备复合油凝胶，探讨复合凝胶剂添加量、单甘酯与蜂蜡质量比、加热温度以及加热时间对油茶籽油基复合油凝胶持油性的影响。在单因素试验的基础上，采用 Box-Behnken 试验设计方法优化试验条件，并对复合油凝胶体系的性质进行分析。结果表明，油茶籽油基复合油凝胶的最优制备工艺条件为：复合凝胶剂添加量9.9%，单甘酯与蜂蜡质量比4∶ 6，加热温度71 ℃，加热时间47 min。在最优工艺条件下，复合油凝胶持油性为98.70%，体系中存在α、 β、 β′ 3种晶型，并且与单一凝胶剂油凝胶相比，油茶籽油基复合油凝胶具有较好的持油性和适中的硬度。 |
| 英文摘要: |
| The oil-tea camellia seed oil was used as the raw material oil,the compound oleogel was prepared by adding monoglyceride and beeswax. The effects of dosage of compound gel agent, mass ratio of monoglyceride to beeswax, heating temperature and heating time on the oil holding capacity of compound oil-tea camellia seed oil oleogel were investigated. Based on the single factor experiment, the Box-Behnken experimental design methodology was used to optimize the test conditions, and the property of compound oleogel system was analyzed.The results showed that the optimal preparation conditions of compound oleogel were obtained as follows: dosage of compound gel agent 9.9%, mass ratio of monoglyceride to beeswax 4∶ 6, heating temperature 71 ℃, heating time 47 min. Under the optimal process conditions, the oil holding capacity of the compound oleogel reached 98.70%, and three crystal forms of α, β and β ′ were in the oleogel system.Compared with the single oleogel, the compound oil-tea camellia seed oil oleogel had better oil holding capacity and moderate hardness. |
