Abstract:
... This study investigated the interaction between egg white protein particles (EWPP) and rhamnolipid (Rha) as co-emulsifiers in high internal phase emulsions (HIPEs). To reveal the effect between EWPP and Rha on the properties of HIPEs, the physicochemical properties (particle size, zeta-potential and microstructure) and emulsifying capacity were investigated. The results showed that, with the incre ...

Abstract:
... Gelation is one of the functional properties of protein, which can be controlled by pH and ionic strength. However, kowledge related to gelation properties of emerging plant proteins is still limited. In this paper, the solubility, the thermal behaviour and gelation behaviour of pea protein were analysed. Gels were analysed rheologically measuring the elastic modulus G′₂₅°C, the ratio of G′₂₅°C to ...

We review these methods, focusing in particular on bubble-scale simulations of foam rheology. We highlight methods that allow the distribution of surfactant during flow to be taken into account. ...

Here however, it is assumed that protein-coated sub-micron droplets contribute to the network formation in a similar way to proteins. Emulsion gels are thus envisioned as composite networks made of proteins and droplets.Emulsion gels with a wide r ...
