Because polyelectrolytes may be biocompatible, it follows that they can be used to stabilize emulsion in foods. Several studies have focused on using polyelectrolytes to induce mixing of proteins and polysaccharides in oil-in-water emulsions. DSS has been successfully used to stabilize these types of emulsions. [25]
Creaming, in the laboratory sense, is the migration of the dispersed phase of an emulsion under the influence of buoyancy.The particles float upwards or sink depending on how large they are and density compared to the continuous phase as well as how viscous or how thixotropic the continuous phase might be.
A dispersant or a dispersing agent is a substance, typically a surfactant, that is added to a suspension of solid or liquid particles in a liquid (such as a colloid or emulsion) to improve the separation of the particles and to prevent their settling or clumping.
The oil is emulsified with detergents using a high-shear mixer to stabilize the emulsion so, when they encounter the lipids in the cell membrane or envelope of bacteria or viruses, they force the lipids to merge with themselves. On a mass scale, in effect this disintegrates the membrane and kills the pathogen.
When the contact angle is approximately 90°, the energy required to stabilize the system is at its minimum. [3] Generally, the phase that preferentially wets the particle will be the continuous phase in the emulsion system. The most common type of Ramsden emulsions are oil-in-water emulsions due to the hydrophilicity of most organic particles.
Emulsions are thermodynamically unstable liquid/liquid dispersions that are stabilized. [1] Emulsion dispersion is not about reactor blends for which one polymer is polymerized from its monomer in the presence of the other polymers; emulsion dispersion is a novel method of choice for the preparation of homogeneous blends of thermoplastic and elastomer. [2]
Flocculation is thus the initial step leading to further ageing of the emulsion (droplet coalescence and the ultimate separation of the phases). Flocculation is used in mineral dressing, [ 7 ] but can be also used in the design of physical properties of food and pharmaceutical products.
In polymer chemistry, emulsion polymerization is a type of radical polymerization that usually starts with an emulsion incorporating water, monomers, and surfactants.The most common type of emulsion polymerization is an oil-in-water emulsion, in which droplets of monomer (the oil) are emulsified (with surfactants) in a continuous phase of water.
