Polyglycerol polyricinoleate

International Numbering System (INS) for Food Additives: 476

Food additives Europe numbers: E476 

Polyglycerol polyricinoleate (PGPR), also known by its European food additive code E476, is an emulsifier commonly used in various food products. Here's a detailed breakdown of its properties and applications:

What is PGPR?

• Made from: It's a man-made compound derived from glycerol (a simple alcohol) and fatty acids, typically from castor oil or soybean oil.
• Chemical structure: PGPR consists of short chains of glycerol molecules linked by ether bonds, with ricinoleic acid side chains attached by ester bonds.

Function of PGPR in Food:

• Emulsifier: The primary function of PGPR in food is as an emulsifier. It helps stabilize mixtures of ingredients that wouldn't normally blend well together, like oil and water. This is crucial for achieving a smooth and consistent texture in various food products.
• Specific applications: Here are some common uses of PGPR:
  • Chocolate and confectionery: In chocolate, PGPR helps reduce viscosity (thickness) and improve flow properties. This allows for easier molding and enrobing (coating) of chocolates. It can also help reduce fat bloom, which is the whitish discoloration that can appear on stored chocolate.
  • Low-fat spreads and dressings: PGPR aids in incorporating more water into low-fat formulations of spreads, salad dressings, and mayonnaise, maintaining a desirable texture.
  • Baked goods: In some bakery products, PGPR can improve crumb texture and overall quality.

Safety and Regulations:

• Generally recognized as safe (GRAS): PGPR is generally recognized as safe (GRAS) by regulatory bodies like the US FDA. Studies have shown no adverse effects on human health at typical consumption levels.

Additional Considerations:

• Kosher and Halal: PGPR is suitable for use in Kosher and Halal food products as it's derived from vegetable sources.
• Dosage: The amount of PGPR used in food is typically very low, usually less than 0.5%.

Overall:

Polyglycerol polyricinoleate is a valuable emulsifier in the food industry, playing a key role in achieving desirable textures and functionalities in various food products. It's considered safe for consumption at permitted levels.
