Are monoglycerides vegan? Plant or animal, and 5 products checked

Sometimes. Mono- and diglycerides (E471) are made from fats or oils, and the FDA’s definition asks only that they come from “edible sources”, which covers both soybean oil and animal fat. A vegan label on the product settles it. Without one, only the maker can tell you which it used.

That phrase, “edible sources”, is the whole problem in two words. The federal rule that makes mono- and diglycerides generally recognized as safe defines them by chemistry, a mix of mono- and diesters of glycerin made from fats, oils or fat-forming acids, and sets no limit beyond good manufacturing practice. It never says plant or animal, and nothing in that section puts the source on the label. The USDA’s technical review of glycerides says the edible sources are commonly animal fats or vegetable oils such as soybean, canola and sunflower. So the same five words on a bread bag can mean either, and you are left doing what we do for every other vague ingredient: reading the guide to checking whether ingredients are vegan and then emailing the company.

What decides it

Mono- and diglycerides are emulsifiers. The USDA review lists them as dough strengtheners and finds them in margarine, salad dressing, peanut butter, ice cream and instant pudding. They are made mostly by reacting glycerin with fats or oils, and the review names glycerolysis of vegetable oils as one of the most common methods, while noting that animal fats may also be the starting material. The same review classifies them as synthetic, because both main production methods involve chemical reactions. Plant-sourced or not, this is a processed ingredient, which matters only if you were hoping otherwise.

The kosher certifier OK Kosher puts the practical problem plainly. Vegetable oils and animal fats share the same chemistry, and the raw materials can be derived from animal fat or run on the same equipment as animal fat. You cannot taste or test the difference in the finished bread. You can only be told.

So the decision has three outcomes:

The product carries a vegan claim or certification. The maker has done the checking, and the mono- and diglycerides are plant-sourced.
The maker says where they come from, on its site or in an FAQ. Then you know, and you still read the rest of the list.
The label says neither and the maker has not answered. Then the honest answer is “unknown”, and unknown is not vegan.

Five products, checked on the maker’s page

Oatly Chocolate Frozen Dessert

Oatly lists “mono- and diglycerides of fatty acids” in its chocolate frozen dessert, alongside oat milk, coconut oil and rapeseed oil, and marks the product vegan on the same page. That is the easy case. The vegan claim covers every ingredient, the emulsifier included, so nothing is left to ask. Buy it if the emulsifier was your only worry.

Jif Creamy Peanut Butter

This one is more interesting. Jif Creamy lists mono and diglycerides among its minor ingredients. Jif’s own FAQ says its peanut butter is vegetarian because it “uses ingredients sourced from plants”, and in the next breath says its products “are not considered vegan at this time” because some, such as Jif Natural and Honey, contain ingredients of animal origin. So by the maker’s account the emulsifier in the creamy jar comes from plants, and the brand still will not call the jar vegan, because the honey jar shares the name. Most vegans we know would eat the creamy one on that statement. If you want a maker’s vegan label rather than a reading of its FAQ, this is not the jar.

Jif Natural Creamy Peanut Butter

The swap, if you would rather not think about it. Jif Natural Creamy lists peanuts, sugar, palm oil, salt and molasses, and no mono- and diglycerides at all. Jif’s FAQ calls palm oil “an alternative stabilizer”, which is the job the emulsifier does in the regular jar. Whether palm oil is a better choice is a different argument, and one Jif’s own FAQ addresses in its sourcing answer.

Häagen-Dazs (Nestlé Canada)

Nestlé Canada is one of the few makers that answers the question directly. Its ingredient-origin FAQ says the mono and diglycerides in its ice cream products, Häagen-Dazs among them, are plant-based. Which is a real answer, and a useless one for a vegan, because the ice cream is still ice cream. It is a good reminder that a plant-sourced emulsifier says nothing about the cream it is emulsifying. The same FAQ tells readers to check the label first for current information.

Pan Molido Original Bread Crumbs

The common case. Bimbo’s Pan Molido Original Bread Crumbs lists monoglycerides, and the brand’s SmartLabel page describes them only as “a food additive manufactured from glycerin and fatty acids that is used as an emulsifier”. No source, no vegan claim. Don’t buy it on the assumption that the emulsifier is plant-based; ask Bimbo, or pick crumbs whose list has no mono- or diglycerides.

Which to buy

If the label says vegan, stop worrying about the emulsifier: Oatly’s frozen dessert is the example here. If the maker states the source, as Jif and Nestlé Canada do, you have an answer, but read the rest of the list, because a plant-based emulsifier in a dairy ice cream is still in a dairy ice cream. If there is neither, as with the bread crumbs, treat it as unknown and either ask or buy the version without it.

E471 is the European code for the same additive, and it carries the same problem. The same goes for other insect- and animal-derived additives hiding behind a number, which is why our piece on whether shellac is vegan reads the E904 on candy the same way.
