Mono- and diglycerides

Mono- and diglycerides are emulsifiers made from glycerol and fatty acids of plant or animal origin.

Also on labels: E471 · glyceryl monostearate · distilled monoglycerides

Mono- and diglycerides are source-ambiguous: the fatty acids can come from vegetable oils or from animal tallow, and the finished label reads identically either way — E471. Most modern production is vegetable-based, but nothing on the label proves it, which is why a certification review asks the supplier for the fat source in writing.

What it means for each mark

  • VeganPasses only with a supplier declaration that the fatty-acid source is vegetable; tallow-derived E471 is excluded.
  • VegetarianThe same source question applies — tallow-derived material is excluded, vegetable-derived passes.
  • Gluten-FreeThe emulsifier itself is fat-derived; carrier systems in powdered forms are confirmed against the certificate's stated threshold.

Where it typically hides

  • Breads, tortillas and packaged baked goods
  • Margarine and spreads
  • Ice cream and whipped toppings
  • Peanut and nut butters (stabilizer)
  • Coffee whiteners and chewing gum

What a certification review asks for

  1. A fatty-acid source declaration (vegetable or animal) for E471 and its ester family (E472a–f)
  2. The carrier composition for powdered emulsifier forms
  3. For gluten-free scope: the carrier's identity confirmed against the certificate's threshold

Alternatives

  • Sunflower or soy lecithin (E322)
  • E471 with a documented vegetable source — the same additive, evidenced
  • Enzyme-based dough improvers in bakery applications

Frequently asked questions

Are mono- and diglycerides vegan?

They can be. The additive is made from glycerol and fatty acids that may be vegetable or animal in origin. The label does not distinguish them, so vegan status rests on a written source declaration from the supplier.

Do mono- and diglycerides contain gluten?

The emulsifier itself is fat-derived. What a gluten-free review confirms is the carrier system used in powdered forms, checked against the ppm threshold stated on the certificate.
