Is monk fruit legal in the UK and EU?
Yes, in the right form. Monk fruit infusion powder made from non-selective aqueous decoctions is allowed in the UK and EU, because in that form it is not treated as a novel food. The legal position turns on how the product is made, so traditional decoction powders and highly purified extracts are not the same category.
The legal position, briefly
- Monk fruit decoction powder is allowed in the UK and the EU.
- Its status depends on how the product is made, not just on the words "monk fruit".
- Whole-fruit decoctions and purified mogroside extracts sit in different regulatory boxes.
If you have wondered whether monk fruit sweetener is actually allowed on this side of the world, you are not alone. It is one of the most common questions we get, and 2024 brought a lot of overdue clarity.
The full picture is below, with links to the official sources so you can check it yourself rather than take our word for it.
What is a novel food, and why does it matter?
In the UK and EU, a food that was not widely eaten before May 1997 can be classed as a "novel food". That means it has to pass a safety assessment before it can be sold. Monk fruit has been used in Chinese cooking and traditional medicine for centuries, but because it was not common in Western diets before that 1997 cut-off, regulators had questions about it for years.
The UK ruling: monk fruit decoctions are not novel
In March 2024, the High Court of England and Wales found that the Food Standards Agency (FSA) had been wrong to classify monk fruit decoctions as a novel food. The court decided the FSA had applied criteria that were stricter than the regulations actually required.
Following that, in June 2024 the FSA issued a formal determination: non-selective aqueous decoctions of monk fruit are not a novel food in Great Britain. Traditional monk fruit preparations were found to have an established history of consumption, so they do not need special authorisation to be sold.
The evidence was hard to argue with. Researchers documented an estimated 5.2 million servings of monk fruit consumed in the UK in 1996 alone, largely within Chinese food businesses and communities. You can read the FSA's determination in full here:

And in the EU? Cleared there too
The EU took a similar path. Through 2024, individual member states reviewed the evidence and reached the same conclusion: monk fruit decoctions have a history of significant consumption before 1997. Ireland's Food Safety Authority (FSAI) was the last EU member state to confirm this, in October 2024, which completed the picture across the Union.
The EU's Novel Food Catalogue entry for monk fruit reflects this updated status:

Separately, the EU also authorised one specific aqueous extract of monk fruit for use in several food categories under Commission Implementing Regulation (EU) 2024/2345. That is a narrower approval than the decoction position, and it does not cover every purified extract on the market, but it is another step forward for monk fruit ingredients in European food.
How does this compare with the rest of the world?
Monk fruit sweeteners have been used and approved in many countries for years:
- United States: Generally Recognised as Safe (GRAS) since 2010.
- Australia and New Zealand: approved.
- Canada: approved.
- Japan: used for decades.
- China: traditional use going back centuries.
The UK and EU have now largely caught up with that global picture.
Decoctions vs extracts: what is the difference?
You will see different terms floating around: "monk fruit extract", "monk fruit sweetener", "mogrosides". They are not interchangeable, and the difference is exactly what the legal status hangs on.
A monk fruit decoction is made by steeping or simmering the whole dried fruit in water. It is the traditional method used in China for centuries, and it is the type of preparation the FSA and EU member states have formally recognised as not novel. If you want the fuller story of how the powder is made, we cover it in how monk fruit powder went from novel food to regular ingredient.
A highly purified monk fruit extract is a concentrated product where specific sweet compounds, the mogrosides, are separated out, often to 50 percent concentration or higher. Those concentrated extracts are handled differently by regulators, and the most purified forms are generally not yet approved as food additives in the UK or EU. If you want to know what a single mogroside actually is, we explain it in what is mogroside V?.
Where does Zilch sit? Zilch is a monk fruit infusion powder made by the traditional aqueous decoction method, with a soluble tapioca fibre carrier. It is not a highly purified mogroside extract. That matters here because the decoction route is the one the FSA and EU member states have recognised.
A quick note on the alternatives
Regulatory status is not the same across every sugar alternative, and this is where a lot of confusion creeps in.
- Erythritol is an approved sweetener in the UK and EU, listed as additive E968, and it is widely sold. So the difference with Zilch is not availability. It is simply that Zilch contains no erythritol and no sugar alcohols at all. We go into why in Monk fruit without erythritol: why it matters.
- Allulose is a different story. It is not currently authorised for sale as a food ingredient in the UK or EU, so you will not find it legally on UK shelves yet, whatever US recipes and videos might suggest.
The general framework for how the EU authorises sweeteners, by name or E number, is set out by EFSA here:
What this means for you
The regulatory picture for monk fruit in the UK and EU is clearer than it has ever been. Official bodies on both sides of the Channel have accepted that monk fruit decoctions have an established history of safe consumption.
Honestly, we spent a fair bit of time reading these determinations line by line before we were comfortable putting the word "legal" in a blog title, because getting this wrong is not the kind of thing you want to be casual about. The short version is that you can sweeten your tea, coffee, porridge or yoghurt knowing that Zilch sits squarely in the decoction category regulators have recognised.
