This project aimed to explore the influence of the interaction between ovotransferrin fibrils (OTF) and gum arabic (GA) on the formation mechanism, physicochemical properties, and curcumin delivery of the oleogel-in-water Pickering emulsion. Cryo-scanning electron microscopy results showed that OTF—GA complexes effectively adsorbed on the oil–water...

Context 1
... green circular area corresponded to the oil phase after Nile red staining, and the red fluorescent luminescent layer represented stabilizers after Nile blue A staining. As could be seen from Figure 2, the appearance of the green circular area representing the oil phase indicated that the oil phase was located inside the droplet, which suggested that OPE and OGPE were indeed O/W type Pickering emulsions. Furthermore, it was observed that a large number of fibrils matrices surrounded the emulsion droplets, indicating that OTF and OTF-GA complexes could effectively adsorb on the surface of the emulsion droplets to stabilize OPE and OGPE [4]. ...
Context 2
... to the removal of water from the sample during the sublimation process prior to CryoSEM observation, only solid particles and oil phases were present in the image. Figure 3(a1,a2) shows CryoSEM images of OTF-stabilized OPE, and Figure 3(b1), as well as Figure 3(b2), shows CryoSEM images of OTF-GA complexes-stabilized OGPE. As can be seen from Figure 3, there was network structure between the droplets of both emulsions, which was due to the presence of OTF in both emulsions. ...
