What is Rheology of Pickering Emulsions?

Rheology of Pickering emulsions studies the viscoelastic properties, yield stress, and thixotropic behavior arising from jammed colloidal particle layers at oil-water interfaces under shear.

This subtopic examines how particle-stabilized emulsion networks exhibit creep recovery and shear-thinning due to interfacial jamming. Key models describe yield stress evolution in food-grade formulations. Over 20 papers since 2011 characterize these dynamics, with Deshmukh et al. (2014) cited 220 times for hard/soft colloid rheology.

Key Challenges

Why It Matters

Rheological control in Pickering emulsions enables stable food products like sauces and creams with enhanced mouthfeel (Berton-Carabin et al., 2018; Tan and McClements, 2021). Cosmetic formulations benefit from thixotropic profiles for spreadability and recovery (Chen et al., 2020). Industrial scalability relies on understanding particle jamming for tailored stability (Deshmukh et al., 2014).

Key Research Challenges

Modeling yield stress evolution

Predicting yield stress in jammed particle layers remains difficult due to variable particle interactions at interfaces (Deshmukh et al., 2014). Creep recovery experiments show inconsistencies across particle types (Mendoza et al., 2013). Food-grade particles add complexity from polydispersity (Franco Ribeiro et al., 2021).

Quantifying thixotropy under shear

Thixotropic recovery in Pickering emulsions varies with shear history, challenging standard viscometers (Berton-Carabin et al., 2018). Interfacial rheology decouples bulk from surface effects poorly (Binks, 2017). Applications in cosmetics require real-time modeling (Gonzalez Ortiz et al., 2020).

Scaling lab to industrial rheology

Microfluidic insights from lab emulsions fail to predict large-scale behavior (Anna, 2015). Particle network disruption under high shear alters stability (Dickinson, 2014). Food industry needs validated models for continuous processing (Tan and McClements, 2021).
