Are Monoglycerides and Diglycerides Vegan? (E471)


The short answer for this question is that some monoglycerides and diglycerides are vegan, and some are not.

Sorry to say, there’s no easy answer that always applies.

The reason is because glycerides are made commercially by a reaction between triglycerides and glycerol.

If you’ve read my post on if glycerol is vegan, you’ll know that some glycerol comes from plant sources, and some comes from animal sources.

To make things worse, the main plant sources are soybeans (clearly vegan) and palm oil (which many vegans avoid).

Takeaway: Most monoglycerides and diglycerides are not vegan, although some are. If you want to be sure, you’ll need to contact the company in question, find out where they source their monoglycerides, and then contact that source.

…It’s a real headache when you just want to buy a loaf of bread.

Even though glycerides are in a lot of food, you can usually find a similar alternative that doesn’t use them. That’s my preference.

Where Will You See Mono- and Diglycerides in Food?

Glycerides are in all sorts of things.

But the most common places you’ll see them are:

Bread is the big issue for most vegans. I’d recommend Dave’s Killer Bread as a popular bread among vegans if you’ve having issues finding one.

Most sourdough breads are also vegan.

Verdict: Some Glycerides Are Vegan

Let’s summarize the main points from this post.

First, a large portion of monoglycerides and diglycerides are not vegan, but some are.

Some vegans are okay with eating these anyways, as they are only present in very small amounts (typically like 0.1% of the food) – it’s your call.

If you want to be sure if a particular food uses vegan glycerides you’ll need to contact the manufacturer, get their source, and then ask that source how they make their mono- or diglycerides.

Or, just avoid them, like we do with many other non-vegan ingredients.

  • Do you know if Martins Potato Rolls use vegan Mono and Diglycerides? Is there a master list of vegan bakery items?

    It seems like Martin’s sandwhich potato rolls have a couple dairy ingredients so how the Mono and Diglycerides are manufactured lose relevance.

    Tip for future: I’ve noticed quite a few products with Mono and Diglycerides in the ingredients are certified Kosher-Pareve or disclaimed to be so on their websites (jif peanut butters for one example). Pareve foods can’t have dairy or meats/fats… (but can have kosher egg & fish products FYI) … so it’s safe to say Mono and Diglycerides in kosher-pareve foods are from plant sources
