Özet

This study aimed to prepare and evaluate coconut (TWO-CO) and banana flavored (TWO-BN) oleogels from cold-pressed tiger nut oil (TO) and whale spermaceti wax (WW) against a control (TWO) sample. The samples had 8.41–8.45 min of gelation times and over 99.00% of oil binding capacities. Their color values (L, a*, b*), free fatty acidities (2.40–2.66% linoleate), and peroxide values (2.12 ± 0.48–3.43 ± 0.16 meqO2/kg) were acceptable. X-ray diffraction data proved the presence of β' type polymorphs in all samples. The mean peak melting temperatures were 35.82, 39.02, and 36.39 °C for the TWO, TWO-BN, and TWO-CO, respectively. The rheological frequency sweep test showed storage modulus (G´) values of 10–11 kPa for TWO, 13–15 kPa for TWO-BN, and 105–110 kPa for TWO-CO. All samples had structural recovery ability after exposing and ceasing to high shear. Further, all samples have reached the cross-over point (G´ = G´´) at around 38–40 °C. The samples had 29, 16, and 27 volatile aromatic compounds for the TWO, TWO-BN, and TWO-CO, respectively. In conclusion, this study proved that successful oleogels could be prepared with TO and WW, and these underutilized resources could be alternative players in oleogel industry. study aimed to prepare and evaluate coconut (TWO-CO) and banana flavored (TWO-BN) oleogels from cold-pressed
