Pickering emulsions stabilized by biocompatible particles: A review of preparation, bioapplication, and perspective. ![]() This work reviewed the biomacromolecules that can be used to stabilize food-grade HIPPE, the stabilization mechanism of the emulsions, and the research progress of food 3D printing to provide a reference for the development of advanced food products based on HIPPE.ģD printing HIPPE interfacial film rheology solid particle. There is huge potential for future applications in 3D printing of food. As a shear thinning pseudoplastic fluid, HIPPE can be extruded smoothly through 3D printer nozzles, and its high storage modulus can support the structure of printed products. Particles' three-phase contact angles can be adjusted to about 90° by compounding or modification, which is more conducive to emulsion stability. The contact angle can most intuitively demonstrate the hydrophilicity and hydrophobicity of the particles and also determines the type of emulsions (O/W or W/O type). Proteins, polysaccharides, and their composite particles can be used as good particle stabilizers. Pickering emulsions can be adapted for classic face and body creams as well for sunscreens and foundations.High internal phase Pickering emulsion (HIPPE) is a type of emulsion stabilized by solid particles irreversibly adsorbed on an interfacial film, and the volume fraction of the dispersed phase ( Φ) is larger than the maximum packing volume fraction ( Φ max). Studies have also shown that higher levels of oil produce higher viscosities and a natural external phase thickener, such as VIVAPUR CS 032 XV, is recommended rather than synthetic thickeners such as carbomer and sodium polyacrylate. It is important to note the adding too much of these powder can lead to “balling” in the final formulation. The absence of conventional emulsifiers has the added advantage for ethical claims such as “palm free” and “upcycled ingredients” etc.Īfter extensive testing it has been shown that the correct inclusion levels of these two powders is extremely important to ensure stable and effective emulsion products: Recommended use level: VITACEL CS 5 Oat- 3.5% VITACEL CS 5 Apple- 3% Pickering emulsions have a unique skin feel due to the presence of solid “powder” particles and allow the formulator to create 100% Natural products. The particles also contain soluble proteins and exhibit a mild “charge” around the oil droplets which also helps stabilise the emulsion. VITACEL CS 5 Apple and Oat powders both contain hydrophilic and hydrophobic portions which facilitates their positioning at the interface of oil and water thus enabling the formation of emulsions. Pickering Emulsions are typically oil in water emulsions stabilised by solid particles as opposed to conventional emulsifiers. Whilst both the Apple and Oat powders as known for their excellent sensorial properties as well as for their filling and soft focus characteristics, their ability to form Pickering emulsions is less well known. They undergo minimal “mechanical” processes and can be considered “Natural” according to Cosmos and ISO definitions. ![]() These upcycled materials are derived from food industry waste products. JRS are proud to introduce VITACEL CS 5 Apple and VITACEL CS 5 Oat. ![]()
