Mono- and diglycerides, also listed as E471, are an emulsifier that can be made from either plant oils or animal fat, and the label almost never says which. E471 from plants is halal. E471 from animals is halal only if it comes from an animal slaughtered the halal way. Otherwise it is doubtful, and E471 from pigs is haram. Because most products do not name the source, E471 with no source named is treated as doubtful unless the product is halal-certified or the company confirms it comes from plants.

What are mono- and diglycerides?
Mono- and diglycerides, also listed as E471, are among the most common emulsifiers in processed food. An emulsifier is an ingredient that keeps oil and water mixed. You will find E471 in bread, ice cream, chocolate bars, margarine and baked goods. It keeps food smooth and helps it stay fresh longer.
Why is E471 a problem?
E471 can be made from plant oils or from animal fat. Labels in the United States and the UK do not have to say which.
- E471 from plants is halal.
- E471 from animals is halal only if the animal was slaughtered the Islamic way. Otherwise, it is doubtful.
- E471 from pigs is haram.
The trouble is that the label rarely tells you which one was used.
How can you find out if E471 is halal?
- A halal certificate on the product confirms the source of the E471.
- Some companies state that their E471 comes from plants or vegetables. That makes it halal.
- Otherwise, E471 with no source named is best treated as doubtful.
