Foods Containing E470b (Magnesium Salts of Fatty Acids)
E470b (Magnesium Salts of Fatty Acids) is made from fatty acids that can come from plant oils (including palm) or animal fats, used as a emulsifier to help help mix ingredients that would normally separate, like oil and water. Here's where you're most likely to find it on food labels.
Common foods that contain E470b
E470b is used across bread, margarine, chocolate, ice cream, cakes and processed foods. The foods where it appears most often include:
- Bread
- Margarine
- Chocolate
- Ice cream
- Cakes and processed foods
Exact usage varies by brand and recipe — the only way to know for certain whether a specific product contains E470b is to check its ingredients list, where it must be declared by law, either as "E470b" or as "Magnesium Salts of Fatty Acids".
How to spot E470b on a label
In the UK and EU, additives must appear in the ingredients list with their function and either their E-number or full name — for example "emulsifiers: E470b" or "emulsifiers: magnesium salts of fatty acids". In the US the E-number system isn't used, so look for the full name "Magnesium Salts of Fatty Acids" instead.
