Polyglycerol polyricinoleate (PGPR)
Polyglycerol polyricinoleate (PGPR), E476, is an emulsifier made in a three-step process from glycerol and fatty acids (usually castor bean derived). PGPR reduces the viscosity of chocolate and similar coatings and compounds. It works by decreasing the friction between the particles of cacao, sugar, milk, etc. present so they can flow more easily when melted. It is used at low levels (below 1%). It is made up of a short chain of glycerol molecules connected by ether bonds, with ricinoleic acid side chains connected by ester bonds.
PGPR is a yellowish, viscous liquid composed of polyglycerol esters of polycondensed fatty acids from castor oil. It may also be polyglycerol esters of dimerized fatty acids of soybean oil.
PGPR is strongly lipophilic, soluble in fats and oils, and insoluble in water and ethyl alcohol. In chocolates, it is used as a viscosity-reducing agent.It is virtually always paired with lecithin or another plastic viscosity-reducing agent.
It can also be used as an emulsifier in spreads and in salad dressings or as a crystal inhibitor and anticlouding agent in fractionated vegetable oils.
