Is Xanthan Gum Vegan? It Depends On How It’s Produced!

Is xanthan gum vegan?

Xanthan gum, also known as E415 in the EU, is one of those ingredients that vegans often find themselves scratching their heads over trying to figure out whether it's vegan-friendly or not.

The thing is xanthan gum is a particularly confusing food additive for vegans because of how it's produced.

So is xanthan gum vegan?

The answer is it all depends on whether glucose, sucrose or lactose was used in the fermentation process.

If it sounds confusing to you, don't worry. Let's get into the nitty-gritty!

Xanthan Gum: Vegan or Not?

There really isn't one correct answer because it all depends on how the xanthan gum was cultured. You see, as a high-fiber carbohydrate that can be extracted by fermenting sugars, xanthan gum can be produced in a range of different ways.

In most cases, xanthan gum is vegan because it is extracted from the fermentation of corn, soy, or wheat. You can read more about the production below.

However, xanthan gum can also be produced from non-vegan sources such as whey and egg whites. Obviously, xanthan gum that is derived from animal sources cannot be considered vegan.

Unfortunately, there is no easy way for a consumer to know for sure whether the xanthan gum was fermented using a vegan source or an animal derived source. The only option is to contact the manufacturer and ask.

Alternatively, you can stick to buying products that are clearly marked vegan as this will ensure the ingredients are free from any animal derivatives.

If you're looking for a vegan xanthan gum to use in baking, Bob's Red Mill is an option. In fact, Bob's Red Mill clearly states this on their website:

"The bacteria that grows our xanthan gum is fed a carbohydrate substrate produced from Non-GMO corn (UPDATED 8/1/2018)."

With that being said, whey-derived xanthan gum is still used in various products so we advise you to err on the side of caution.
