What is polyglycerol esters?
Polyglycerol esters(also called polyglyceryl esters,polyglycerin esters, polyglycerides,PGFE……), which are esters formed from polyglycerol&fatty acids. They are new kind of polyhydroxy esters non-ionic surfactants with high efficiency and excellent performance.
As a series of fatty acid esters, the emulsifying property of polyglycerol esters is much better than monoglycerides. Because polyglycerol esters have more hydrophilic hydroxyl . Their hydrophilicity increases with the degree of polymerization of glycerol. And their lipophilicity varies with the alkyl groups of fatty acids. Different polyglycerol esters from lipophilic to hydrophilic which are suitable for various special uses.
Polyglycerol fatty acid esters are the general name ofa series of products, which can be used as emulsifiers,stabilizers and structural modifiers for food additives. Becauseof its high safety, it has long been approvedby the Food and Agriculture Organization of the UnitedNations and the WHO as food additives.
