Published: Feb. 18, 2022

There is an increased pressure on food manufacturers to design low calorie and fat foods address the global obesity crisis. Designing double emulsions (DEs) a microstructural approach incorporate water that appears as promising replacement strategy. However, these complex microstructures are thermodynamically unstable thorough understanding of factors determine stability DEs required tailor their functionality. This review provides update main strategies used stabilize DEs, focusing developments in last five years. Emphasis placed recent use surfactants, combination surfactants with gelling agents, particles, crystals, and/or coatings. Novel processing techniques were also reviewed, one-step methodologies particularly examined. We briefly reviewed rheological tribological performance DEs. Properties depend strongly formulation fabrication technique (homogenization, phase inversion, microfluidics, 3D Printing etc). Fat crystal forming shell around droplets offers strategy prevent diffusion internal Pickering stabilization has captured significant research attention, though fabricated solely using particle-laden interfaces limited. A combined bulk by aqueous improve DE, which needs attention. Future studies should focus characterizing link them mouthfeel perception accelerate applications.

Active nematic emulsions

Science Advances, Journal Year: 2018, Volume and Issue: 4(4)

Published: April 6, 2018

The formation of emulsions from multiple immiscible fluids is governed by classical concepts such as surface tension, differential chemical affinity and viscosity, the action surface-active agents. Much less known about emulsification when one components active thus inherently not constrained laws thermodynamic equilibrium. We demonstrate realization consisting in encapsulation an liquid crystal (LC)-like gel, based on microtubules kinesin molecular motors, into a thermotropic LC. These nematic exhibit variety dynamic behaviors that arise cross-talk between topological defects separately residing passive components. Using numerical simulations, we show feedback mechanism which flows continuously drive that, response, resolve otherwise degenerated trajectories defects. Our experiments choice surfactant, stabilizes active/passive interface, allows tuning regularity self-sustained events. hybrid active-passive system demonstrated here provides new perspectives for self-assembly driven material but regulated equilibrium properties component.
