以一级压榨葵花籽油为原料，添加一定浓度的γ–谷维素与β–谷甾醇混合物制备出葵花油凝胶，探究不同制备工艺条件对葵花油凝胶硬度及微观结构的影响。在单因素试验的基础上，通过正交试验确定了6%γ–谷维素与β–谷甾醇混合物添加量葵花油凝胶的最优制备条件。试验表明，影响葵花油凝胶硬度因素的主次顺序为：冷却温度＞γ–谷维素：β–谷甾醇添加比例＞加热时间＞加热温度；6%γ–谷维素与β–谷甾混合物醇添加量葵花油凝胶的最优制备工艺为：加热温度140℃，加热时间50 min，冷却温度5℃，γ–谷维素∶β–谷甾醇添加质量比例60∶40。在最优工艺条件下，6%γ–谷维素与β–谷甾醇添加量葵花油凝胶硬度为479.61±9.18 g。

We prepared sunflower oil organogel by adding a certain concentration ofγ–oryzanol andβ–sitosterol into the base oil(first–degree filter pressed sunflower oil),and explored the effects of different preparation conditions on the firmness and microstructure of sunflower oil organogel. On the basis of single factor experiment,the optimal preparation conditions of 6%γ–oryzanol andβ–sitosterol organogels made with sunflower oil were determined by orthogonal experiment. The results showed that the cooling temperature affected the firmness of sunflower oil organogel significantly,followed byγ–oryzanol andβ–sitosterol weight ratio,heating time and heating temperature;the optimal preparation conditions 6%γ–oryzanol andβ–sitosterol organogels made with sunflower oil were obtained as follows:heating temperature 140℃,heating time 50 min,cooling temperature 5℃andγ–oryzanol andβ–sitosterol weight ratio 60∶40. Under the optimal conditions,the firmness of 6%γ–oryzanol andβ–sitosterol organogels made with sunflower oil reached 479.61±9.18 g.
