Polyglycerol-poliricinoleate

Polyglycerol polyricinoleate (PGPR) is a food additive made from glycerol and fatty acids derived from castor oil. It is produced by heating these ingredients together, which causes them to link up into longer chains.

PGPR functions as an emulsifier, helping to blend ingredients that don't normally mix, like oil and water. This is useful in chocolate and cocoa products to reduce viscosity and improve flow, and can also be found in some baked goods and snack bars.

PGPR is generally recognized as safe (GRAS) by the FDA for use in food. It has been evaluated by the Joint FAO/WHO Expert Committee on Food Additives (JECFA), which has established acceptable daily intake levels. Current scientific evidence does not indicate adverse health effects from consuming PGPR at typical dietary levels.
