葵花籽油基油凝胶在面包及冰淇淋产品中的应用研究

以葵花籽油为基料油,食品级植物蜡(米糠蜡、蜂蜡、棕榈蜡)作为凝胶剂构建油凝胶,分别以黄油、起酥油、葵花籽油作对照烘焙面包,以黄油、淡奶油作对照制备冰淇淋,对比分析不同油脂制作的面包和冰淇淋的感官及物性。结果表明:与对照组面包相比,油凝胶面包在各项指标上均无太大劣势,同时,油凝胶面包烘焙损失率比用传统黄油和起酥油烘焙面包小,且饱和脂肪酸含量降低;在抗融化性能方面,蜂蜡油凝胶冰淇淋和棕榈蜡油凝胶冰淇淋的抗融化性能好于黄油冰淇淋,但油凝胶冰淇淋膨胀率较低,不利于冰淇淋形成疏松绵软结构,且有少许蜡感,还需进一步改进。

Application of sunflower seed oil based oleogels in bread and ice cream products

Sunflower seed oil was used as the base oil, and food grade vegetable wax (rice bran wax, beeswax, palm wax) was used as the gelling agent to build the oleogel. The butter, shortening and sunflower seed oil were used as the control for baking bread, and the butter and whipped cream were used as the control for preparing ice cream. The sensory and physical properties of bread and ice cream prepared by different oils were compared and analyzed. The results showed that the oleogel bread had no disadvantage in all indexes compared with the control bread. At the same time, the loss rate of the oleogel bread was smaller than that of traditional butter and shortening bread, and the saturated fatty acid content was reduced. In terms of anti-melting performance, the anti-melting performances of beeswax oleogel ice cream and palm wax oleogel ice cream were better than that of butter ice cream, but the oleogel ice cream had a low expansion rate, which was not conducive to the formation of loose and soft structure of ice cream, and had a little waxy feeling, so the further improvement was needed.
