Xanthan gum (/ ˈ z æ n θ ə n /) is a polysaccharide with many industrial uses, including as a common food additive.It is an effective thickening agent and stabilizer that prevents ingredients from separating.
Light stabilizer are used to inhibit polymer photo-oxidation, which is the combined result of the action of light and oxygen. Like autoxidation this is a free radical process, hence the antioxidants described above are effective inhibiting agents, however additional classes of additives are also beneficial, such as UV absorbers, quenchers of ...
CMC is used in baking breads and cakes. The use of CMC gives the loaf an improved quality at a reduced cost by reducing the need for fat. CMC is also used as an emulsifier in biscuits. Dispersing fat uniformly in the dough improves the release of the dough from the molds and cutters, achieving well-shaped biscuits without any distorted edges.
Hindered amine light stabilizers (HALS) are chemical compounds containing an amine functional group that are used as stabilizers in plastics and polymers. [1] These compounds are typically derivatives of tetramethylpiperidine and are primarily used to protect the polymers from the effects of photo-oxidation; as opposed to other forms of polymer degradation such as ozonolysis.
The effect of pH on the stability of polyelectrolytes is based upon the functional group on the polymer backbone that is bearing the charge. A protonated amine, for instance, will be much more stable at a lower pH while a sulfonate group will be more stable at a higher pH.
Pectin is used as a stabiliser in foods such as yogurt. A stabiliser or stabilizer is an additive to food which helps to preserve its structure. Typical uses include preventing oil-water emulsions from separating in products such as salad dressing; preventing ice crystals from forming in frozen food such as ice cream; and preventing fruit from settling in products such as jam, yogurt and jellies.
In polymer science, dispersion polymerization is a heterogeneous polymerization process carried out in the presence of a polymeric stabilizer in the reaction medium. . Dispersion polymerization is a type of precipitation polymerization, meaning the solvent selected as the reaction medium is a good solvent for the monomer and the initiator, but is a non-solvent for the po
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.
