Is E471 (mono- and diglycerides) halal?
E471, listed as mono- and diglycerides, is halal when it is made from plant oils (soy, palm, sunflower, rapeseed) or from fat of zabiha slaughtered animals. It is not halal when it comes from pork fat or non-zabiha beef fat. Most labels do not say which, so look for "vegetable" or a halal mark.

What E471 is
An emulsifier made by reacting glycerol with fats or oils. It keeps bread soft, ice cream smooth and spreads from separating, so it is in a lot of packaged food. The American Halal Foundation notes the chemistry does not change where the fat came from, so the source decides the status.
How to check a product
Look for "vegetable mono- and diglycerides", "plant-based" or a recognised halal certification mark. A kosher symbol alone does not settle it, because kosher rules do not require zabiha slaughter. If the label just says E471, ask the manufacturer. The related emulsifiers E472a to E472f, polysorbates and glycerol (E422) raise the same question.
