Abstract
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 nanoscale, it was found that the crystal nanoplatelets (CNPs) of MO1 contained a higher number of lamellae compared with MO2. Additionally, the results obtained with ultra-small angle x-ray scattering indicated a larger equivalent diameter for the CNPs of MO1. As a function of the storage time, both oleogels did not show major structural changes up to 8 weeks of storage.
