The overconsumption ofsolid fatssuch as butter and shortening can cause health concernsrelated to cardiovascular diseases due to their high levels of saturated fatty acids. Therefore many researchers have madea great deal of effort to develop solid fat replacers. In this study, grape seed oil-candelila wax oleogelswere prepared and evaluated as a replacer for shortening in baked goods (specifically muffins). Muffin batters with increasing levels of oleogels exhibited lower viscosity. The reduced porosity of muffins by the shortening replacementwith oleogels could be expected from higherspecificgravity and lowerspecific volume. A stress relaxation test showed that more shortening replacement with oleogels produced muffins with a harder and springier texture. However, the use of the oleogels as a shortening replacer as a ratio of 1:3 by weight was effective in producing muffins with comparable quality attributes to the control with shortening. The ratio of saturatedto unsaturated fatty acids was significantly decreased from 2.81 to0.41 when shortening was replaced with oleogels. Hence, this study showed the possibility of oleogels as shortening replacement in the food industries. The use of oleogels instead of solid fat presents possible opportunities to formulate healthier bakerygoods.

Candelilla wax-in-water nanoemulsions stabilized by Span 80/Tween 80 were prepared by the phase inversion composition (PIC) method. Stable nanoemulsions with droplet diameters below 50 nm could be formed when the hydrophilic–lipophilic balance (HLB) values were between 13.5 and 14.5, surfactant concentration was 5.0 wt%, and the surfactant-wax ratio was 1:1. Increased emulsification temperature and cooling rate were found to improve the emulsion properties. Process of PIC (adding aqueous phase to the wax phase) produced smaller droplet size nanoemulsion compared to the process of adding wax phase to the aqueous phase. The stability of these nanoemulsions was assessed by following the change in droplet diameters with time of storage at room temperature (∼25 °C). The size remained constant during 2 months storage time.
