Canola oil was structured into oleogels with different amounts of carnauba wax, and their processing performances were assessed as an alternative to solid fat for imitation cheese low in saturated fat. The contents of solid fat in the oleogels were less vulnerable to the change in temperature than the palm oil. The replacement of palm oil with oleogels produced cheese samples with harder and more cohesive/chewy textures. Dynamic and transient viscoelastic measurements demonstrated that the use of oleogels was effective in increasing the elastic nature of the cheeses. Two distinct components with different proton mobilities were observed in the imitation cheeses, and longer T relaxation times were detected in the oleogel samples. The meltability of the cheese with palm oil was not significantly different from those with 3% and 6% oleogels. The saturated fat level of the oleogel cheese was significantly reduced from 45.70 to 5.20%. The application of canola oil-carnauba wax oleogels could successfully produce imitation cheese high in unsaturated fat and low in saturated fat. This study thus demonstrated that the health-functional properties of imitation cheese could be enhanced by using oleogels.
菜籽油与不同量的巴西棕榈蜡构成油凝胶,并评估其加工性能,作为饱和脂肪含量低的仿奶酪中固体脂肪的替代品。油凝胶中的固体脂肪含量比棕榈油更不易受温度变化影响。用油凝胶替代棕榈油生产出的奶酪样品质地更硬,更具粘性/嚼劲。动态和瞬态粘弹性测量表明,使用油凝胶可有效提高奶酪的弹性。在仿奶酪中观察到两个具有不同质子迁移率的不同成分,在油凝胶样品中检测到更长的T弛豫时间。含棕榈油的奶酪与含3%和6%油凝胶的奶酪的融化性无显著差异。油凝胶奶酪的饱和脂肪含量从45.70%显著降低至5.20%。菜籽油-巴西棕榈蜡油凝胶应用可成功生产出不饱和脂肪含量高、饱和脂肪含量低的仿奶酪。因此,本研究表明,使用油凝胶可增强仿奶酪的健康功能特性。
