Polyglycerol Polyricinoleate (PGPR) - E 476

Polyglycerol Polyricinoleate (PGPR), identified as the food additive E 476, is a highly effective lipophilic emulsifier primarily used to modify the rheology of fat-based systems.

Key Functions and Benefits

PGPR is invaluable in confectionery and other fat-containing products for its ability to significantly alter viscosity and enhance texture:

Viscosity Reduction (Chocolate): It dramatically reduces the viscosity of melted chocolate and cocoa-based candies at low concentrations. This effect provides a more fluid structure, allowing for easier processing and forming, and helps achieve the desired fineness and flow properties in the final product. Textural Modification: It imparts the desired softness in soft ice cream formulations. Staling Delay (Bakery): In bakery products, it contributes to delaying staling, helping to maintain freshness over time. Oil Binding and Carrier: PGPR exhibits excellent oil binding and carrier properties, making it highly effective in the production of spreadable oils  

Applications

PGPR is essential in formulations where fluid control and textural enhancement are critical:

Confectionery: Chocolate, cocoa-based candies, and general confectionery. Fats and Oils: Spreadable oils (low-fat varieties). Desserts: Soft ice cream. General Food Systems: Sauces and oil emulsion.
