Fig. 2 BFM images of oleogels consisting of MCT-oil and 10 % (w/w) structurant (SFX (a), (c)); WE C34(18_16) (b), (d)) crystallized at different cooling rates. (Image (c): purified canola oil (0 % polar components) as solvent - contrast enhanced)
Fig. 3 Comparison of calculated layer thicknesses (eq. 1, eq. 2) (lines) and experimental SAXS data (marker) as a function of CN; SAXS data:
Fig. 4 Melting temperatures (left) and molar heat of fusion (right) of pure wax esters as a function of CN. Black crosses: experimentally determined for this manuscript, gray circles: reviewed literature data
Fig. 5 Melting temperature of WEs with different symmetries and CN as a function of ∆CN. Lines indicate equal CN. Black crosses: experimentally determined for this manuscript, other markers: reviewed literature data
Fig. 6 DSC heating thermograms for oleogels formed with MCT-oil and 10 % (w/w) of either SFX (gray) or pure WE C42 (22_20) (black)
Fig. 7 Dissolution temperatures (left) and molar heat of fusion (right) as a function of CN for pure WEs (empty gray markers) and mono-ester gels consisting of a single WE (10 % (w/w) and MCT-oil (filled black markers); Circles: ∆CN ∈ [-2;0;2]); squares: (∆CN ∈ [-8; +8]); value for pure WE C46 is extrapolated (dashed gray circle)
Fig. 8 Complex shear modulus G* as function of temperature obtained from temperature test (oscillatory rheology) showing the crystallization (left, gray) and the melting (right, black) curves for an oleogel based on MCT-oil and 10% (w/w) of WE C42 (22_20). Between the two temperature tests, an isothermal phase (5 °C) was performed for 30 min

Fig. 11 Complex shear modulus G* as function of temperature obtained from an oscillatory rheology temperature test for oleogels consisting of MCT-oil and 10 % (w/w) of either pure WE (C30 (16_14) and C42 (22_20) - gray) or binary mixtures of these WEs at three different mixing ratios (2:1; 1:1; 1:2 – black)
