Polyglycerol esters of fatty acids (PGEs, E475) are non‑ionic food emulsifiers synthesized by esterifying polyglycerol with fatty acids. They exist as oily liquids, pastes or waxy solids depending on fatty‑acid chain length.
Their HLB values cover a wide range, enabling both oil‑in‑water and water‑in‑oil emulsification. They stabilize emulsions, inhibit fat crystallization and modify dough properties in food. They are heat‑stable and compatible with other surfactants. Approved globally for food use, they are widely applied in bakery, margarine, confectionery and whipped products under regulated dosages.
Polyglycerol esters of fatty acids (PGEs, E475) are versatile non‑ionic emulsifiers with adjustable HLB values, produced by esterification of polyglycerol and fatty acids. They can realize both oil‑in‑water and water‑in‑oil emulsification, and remain stable under high‑temperature processing conditions. They are widely used across multiple food categories for emulsion stabilization, texture modification and shelf‑life improvement.
In bakery products, PGEs deliver prominent performance in cakes, bread and whipped fillings. For sponge cakes, they assist aeration during batter whipping, trap fine air bubbles, increase cake volume and generate fine, uniform crumb structure. They improve batter stability, avoid layer separation before baking. In bread, they interact with starch to retard retrogradation, keeping crumb soft and slowing staleness. They also enhance dough tolerance against over‑mixing and freeze‑thaw cycles for frozen dough products.
In margarine, shortenings and fat spreads, PGEs control fat crystal formation. They restrain coarse crystal generation, prevent oil exudation and surface blooming. For low‑fat margarine, they stabilise water‑in‑oil emulsion system, improve spreadability under refrigeration and avoid product cracking during storage. Combined with monoglycerides, they produce synergistic emulsifying effects and reduce total additive dosage.
Confectionery is another major application field. In chocolate and compound coatings, PGEs reduce viscosity, improve pouring and enrobing performance. They inhibit fat bloom to avoid surface whitening. In cream fillings and nougat, they stabilise oil‑water system, prevent oil leakage and maintain smooth texture. For whipped confectionery toppings, they stabilise whipped foam, prevent foam collapse and shape deformation.
In dairy and plant‑based alternatives, PGEs stabilise non‑dairy creamers, whipped toppings and plant milk beverages. They prevent fat globule aggregation and floating oil after sterilization and cold storage. They improve foam persistence of coffee whiteners. In processed cheese, they enhance melting property and avoid oil separation upon heating.
PGEs are also added to ice cream and frozen desserts. They improve fat aggregation, stabilise air cells, inhibit large ice‑crystal growth, deliver smooth mouthfeel and reduce melting speed. In instant powdered food, they boost wettability and dispersion, lessen caking.
Proper dosage control is required. Excessive addition may bring greasy off‑flavour. PGEs are often compounded with SSL, lecithin and monoglycerides to optimise function. Compliant with global food standards, they are indispensable multi‑functional emulsifiers for modern food industrial production.
