The aim of this study was to examine the physical properties of margarines prepared from oleogels with binary mixtures of candelilla wax (CDW) and beeswax (BW) in soybean oil. Some of the margarines made from oleogels with mixtures of CDW and BW had higher firmness than those made with one wax. For example, a 3% wax margarine made with 25% CDW and 75% BW had significantly higher firmness (0.97 N) than those with 100% CDW (0.59 N) and with 100% BW (0.11 N). Differential scanning calorimetry (DSC) and solid fat content (SFC) analyses revealed eutectic melting properties for binary wax margarines, which may be desirable since wax oleogel-based margarines often have higher melting points than conventional margarines. For example, the major melting point of 3% wax margarine made with 50% CDW and 50% BW was 43.85 °C, while for margarines made with 100% CDW or 100% BW, the melting points were at 46.00% and 47.61 °C, respectively. SFC was lowest for margarines with 50 or 75% BW; for example, 3% wax margarine with 25% CDW and 75% BW had 0.72% SFC at 40 °C while those with 100% CDW and 100% BW had 1.19 and 1.13% SFC, respectively. However, dropping point constantly decreased with increasing BW ratios. This study demonstrated that by mixing two waxes, the firmness of oleogel-based margarines could be increased, and the melting point could be tailored by the ratio of two waxes. PRACTICAL APPLICATION: This study demonstrated that firmness and melting properties of margarines prepared from wax-oleogels can be improved by mixing two waxes, making their practical application more feasible. Firmness of margarines prepared with oleogels of binary mixtures of candelilla wax and beeswax were higher than those with pure waxes. The melting point of wax oleogel-based margarines was decreased by use of binary mixtures of candelilla wax and beeswax.
本研究旨在研究由菜籽油中油凝胶形成的二元混合物坎迪利蜡(CDW)和蜂蜡(BW)制备的人造黄油的物理性质。一些由 CDW 和 BW 混合物制成的油凝胶人造黄油比由一种蜡制成的人造黄油硬度更高。例如,由 25%CDW 和 75%BW 制成的 3%蜡人造黄油的硬度(0.97N)明显高于由 100%CDW(0.59N)和 100%BW(0.11N)制成的人造黄油。差示扫描量热法(DSC)和固脂含量(SFC)分析表明,二元蜡人造黄油具有共晶熔化特性,这可能是理想的,因为基于蜡油凝胶的人造黄油的熔点通常高于传统人造黄油。例如,由 50%CDW 和 50%BW 制成的 3%蜡人造黄油的主要熔点为 43.85°C,而由 100%CDW 或 100%BW 制成的人造黄油的熔点分别为 46.00°C 和 47.61°C。SFC 最低的是含有 50%或 75%BW 的人造黄油;例如,由 25%CDW 和 75%BW 制成的 3%蜡人造黄油在 40°C 时的 SFC 为 0.72%,而由 100%CDW 和 100%BW 制成的人造黄油的 SFC 分别为 1.19%和 1.13%。然而,滴点随着 BW 比例的增加而不断降低。本研究表明,通过混合两种蜡,可以提高基于油凝胶的人造黄油的硬度,并可以通过两种蜡的比例来调整熔点。实际应用:本研究表明,通过混合两种蜡,可以改善由蜡-油凝胶制备的人造黄油的硬度和熔化性能,使其实际应用更加可行。由 Candelilla 蜡和蜂蜡的二元混合物制成的油凝胶人造黄油的硬度高于纯蜡制成的人造黄油。使用 Candelilla 蜡和蜂蜡的二元混合物降低了基于蜡油凝胶的人造黄油的熔点。
