The food additive named polyglycerol polyricinoleate (PGPR) and identified with the code E-476 (PGPR) is used as emulsifier in tin-greasing emulsions for the baking trade and for the production of low-fat spreads. It is a viscous amber coloured liquid and is insoluble in hot and cold water, soluble in … Results: The results showed a rapid decease in Customer Service. Polyglycerol polyricinoleate (PGPR), E476, is an emulsifier made from glycerol and fatty acids (usually from castor bean, but also from soybean oil).In chocolate, compound chocolate and similar coatings, PGPR is mainly used with another substance like lecithin to reduce viscosity.It is used at low levels (below 0.5%), and works by decreasing the friction between the solid particles (e.g. This food additive is a viscous amber coloured liquid. [2] PGPR can also be used to reduce the quantity of cocoa butter needed in chocolate formulations: the solid particles in chocolate are suspended in the cocoa butter, and by reducing the viscosity of the chocolate, less cocoa butter is required,[2] which saves costs, because cocoa butter is an expensive ingredient, and also leads to a lower-fat product. [6], Because PGPR improves the flow characteristics of chocolate and compound chocolate, especially near the melting point, it can improve the efficiency of chocolate coating processes: chocolate coatings with PGPR flow better around shapes of enrobed and dipped products,[7][8] and it also improves the performance of equipment used to produce solid molded products:[8] the chocolate flows better into the mold, and surrounds inclusions and releases trapped air more easily.
