| Popis: | Organogels have emerged as an alternative to the intake of saturated fats. Organogels of soybean oil (SBO) structured with polyglycerol esters (PGE) or propylene glycol esters (PPGE) at different concentrations (0.5, 1.0, 2.0, 3.0, or 4.0%) were formulated. Both emulsifiers at 4% (w/w) concentrations were able to form solid-like organogels and showed thixotropy and low mechanical resistance when compression forces were applied. However, the SBO/PGE (4%) organogels presented lower values for flow curves and micrographs showed a more organized network compared to the SBO/PPGE at 4%. However, higher flow curve values, larger crystals, and mechanical resistance on compression were observed after a two-month storage period of SBO/PPGE compared to SBO/PGE organogels. Both organogels have the potential to be used for diverse food applications although the SBO/PGE was more stable throughout storage. |
