Abstract

The aims of this study were to prepare butter and honey flavoured tiger nut oil oleogels with beeswax oleogelator and to compare them with the unflavoured control sample. The oleogels prepared with 10 wt% beeswax and 0.5 wt% of each flavour addition were analysed for main physicochemical, thermal, and structural properties. In addition, a trained panel described the samples with 11 sensory descriptive (hardness, spreadability, roasted, liquefaction, rancid, waxy, nutty, butter, honey, cooling, and mouth coating) terms. It was found that the oleogels melt around 52 °C and included β′ type polymorphs. The sensory data proved that the samples were quite well spreadable and had enough hardness to stay as solid-fat samples at room temperature. Further, addition of butter and honey flavours masked the waxy attribute. In conclusion, flavoured tiger nut oil-beeswax oleogels were new and successful products, and future studies with food applications are suggested.
