Polyglycerol polyricinoleate (PGPR) is a food additive made from polyglycerol and fatty acids derived from castor oil. It is produced by reacting polyglycerol with fatty acids, typically ricinoleic acid from castor beans.

PGPR is used as an emulsifier in foods, helping to blend ingredients that normally don't mix, like oil and water. It is commonly found in chocolate and cocoa products to improve texture and flow, and can also be used in baked goods and some fat-based coatings.

The U.S. Food and Drug Administration (FDA) lists PGPR as Generally Recognized As Safe (GRAS) for use as an emulsifier. International bodies like the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have also evaluated PGPR. At typical consumption levels, it is not associated with adverse health effects.
