- 01HMGE7G1BC5PAHTFYGWYZ7AX4 abstract "Polyglycerol polyricinoleate (PGPR) is widely used as low-hydrophilic-lipophilic balance emulsifier in the preparation of water in oil (W/O) emulsions or double (W/O/W) emulsions due to its excellent surface activity. Several authors have reported that the presence of water-soluble surface-active compounds (e.g. proteins) strongly influences the absorption behaviour of PGPR at oil-water interfaces, where the simultaneous adsorption of PGPR and proteins has been studied by dynamic surface tension and interfacial dilatational rheology [1]. In order to further understand the interaction between proteins and PGPR in the emulsion stabilization mechanism, this study investigated the sequential adsorption of PGPR and proteins (i.e. whey protein isolate (WPI), sodium caseinate (NaCas) and bovine serum albumin (BSA)) at the oil-water interface by using a modified drop tensiometer allowing external phase exchange. During the experiments, Milli-Q water was replaced by a protein solution after 0.2 % PGPR 4175 (Palsgaard) was equilibrated at a glyceryl triheptanoate/water interface for about 3 hours. The obtained results showed that the interfacial tension of the pre-adsorbed PGPR 4175 films was stabilized at around 6 mN/m and decreased with the addition of WPI and NaCas, whereas the addition of BSA had no effect. Moreover, the addition of the three types of protein increased the dilatational elasticity modulus of the PGPR 4175 films. In addition, no change in the modulus of the PGPR 4175 films was detected at the initial stage of protein addition. These results indicated that the proteins may interact with previously adsorbed PGPR at the oil-water interface through hydrophobic interactions rather than replacing PGPR at the interface, thereby increasing the thickness of the interfacial film.".
