摘要: 以蜂蜡-单甘酯复合凝胶剂制备的核桃油凝胶为研究对象,探究在复合凝胶剂融化前后进行超声处理对核桃油凝胶结构与性质的影响。结果表明:蜂蜡与单甘酯质量比为3∶7时,所制备核桃油凝胶的持油率(OBC)在95% 以上,具有光滑稳定的表观形态;在一定剪切应变范围内,所有核桃油凝胶均呈现出类固体的弹性性质,且经100 W-30 s超声处理所制备的核桃油凝胶具有较强的机械性能;超声处理可改善核桃油凝胶的晶体结构,产生更致密、细小的晶体形态,有效提高核桃油凝胶的OBC和热稳定性;搅打核桃油凝胶可获得裱花性能优异的油泡沫,且超声处理可显著提高核桃油凝胶的起泡率。综上,超声处理可改善核桃油凝胶的结构与性质,使其成为人造奶油的良好替代品。

Abstract: The walnut oil oleogels prepared by beeswax and monoglyceride was used as the research object and the effects of ultrasound treatment before or after complex oleogelators melting on the structure and properties of the walnut oli oleogels were explored. The research results indicated that when the mass ratio of beeswax to monoglyceride was 3∶7, the formed walnut oil oleogels had an oil bonding capacity (OBC) of over 95% and a smooth and stable surface morphology. All walnut oleogels showed solid-like elastic properties within a certain shear strain range, and the walnut oil oleogels prepared with 100 W-30 s parameters had the strongest mechanical properties. Ultrasound treatment could improve the crystal structure of walnut oil oleogels, produce more compact and fine crystal morphology, and effectively enhance OBC and thermal stability of walnut oil oleogels. The oleofoams obtained by whipping the oleogels exhibited excellent decorative performance, and ultrasound treatment could significantly increase the overrun of the walnut oil oleogels. In sum, ultrasound treatment could improve the structure and properties of walnut oil oleogel, and make it a good substitute for margarine.
