Multiscale analysis of monoglyceride oleogels during storage.

Oleogelation offers the possibility to reduce the saturated fatty acid (SAFA) content while maintaining the desired organoleptic properties. Hereby, SAFAs are replaced by other structurants which can create a three-dimensional network that immobilizes the liquid oil. Depending on the type of structurants, different structuring routes are identified. The use of monoacylglycerols (MAGs) as structurants is a promising approach thanks to their great self-assembling properties. However, implementation into the food industry is still hampered due to insufficient characterization. This research includes a multiscale analysis of two dynamically produced MAG-based oleogels (6% MAGs in oil, MO1 and MO2) as a function of the storage time (up to 8 weeks). Slight differences in the production process resulted in pronounced differences in techno-functional properties of the MAG-based oleogels. MO1 consisted of larger crystals, which resulted in a lower rigidity, reduced stability, and lower oil binding capacity compared with the other oleogel (MO2). On the...
