Polyglycerol polyricinoleate (PGPR) is a food additive commonly used as an emulsifier in chocolate and similar products. It is made up of a polyglycerol ester of polycondensed fatty acids from castor oil, primarily ricinoleic acid.
PGPR serves as an emulsifier, which means it helps to blend ingredients that typically wouldn’t mix well together, such as oil and water. In chocolate production, PGPR is often used to improve the viscosity and flow properties of chocolate, allowing it to be more easily processed and molded. It can also help to reduce the amount of cocoa butter needed in chocolate formulations, making it a cost-effective ingredient.
PGPR is considered safe for consumption by regulatory agencies like the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA) when used in accordance with good manufacturing practices and within specified limits. It is generally recognized as safe (GRAS) for use in food products. However, as with any food additive, some individuals may have sensitivities or allergies, so it’s always essential to check ingredient labels if you have specific dietary concerns.
