A chewable tablet, gummy or drink stick lives or dies on taste, and taste usually means a sweetener and a flavouring somewhere in the formula. Most of the common choices — sucralose, acesulfame K, stevia, erythritol and other sugar alcohols — are permitted in Japan, the EU and the US alike. But how each one got approved, and what has to appear on the label because of it, differs enough that a formula built for one market can need a second look before it goes to a Japan-made specification.
This guide covers the approval route and label treatment for the common high-intensity sweeteners, stevia, sugar alcohols and flavourings, and where Japan’s rules meet or part ways with the EU and the US.
💬 Choosing a sweetener or flavouring system for a Japan-made product? We check it against Japan’s current additive list before it reaches specification. See Japan-made supplement OEM.
High-intensity sweeteners: sucralose and acesulfame K
Sucralose and acesulfame K are both designated food additives in Japan, each individually approved decades ago, and both also sit on the EU’s and the US’s own sweetener lists under a different legal route.
| Sweetener | Japan | EU | US |
|---|---|---|---|
| Sucralose | Designated food additive since 30 July 1999, with a use standard and compositional specification | Authorised food additive (E955) under Regulation (EC) No 1333/2008 | FDA-approved food additive |
| Acesulfame K | Designated food additive, approved by the health ministry on 25 April 2000 | Authorised food additive (E950) under Regulation (EC) No 1333/2008 | FDA-approved food additive |
Both sweeteners reached essentially the same destination — permitted use, with a use-category label requirement — through separate national and regional review processes. A Japan-made product using either one needs the Japanese “sweetener (substance name)” label wording, which does not automatically match how the same product is labelled for the EU or US market.
Stevia: an ingredient with Japanese roots
Stevia extract has been used as a sweetener in Japan for decades and sits on Japan’s existing food additives list, while the EU and US only authorised purified steviol glycosides more recently and through their own separate routes.
Stevia extract and its glucosyltransferase-treated form are both on Japan’s list of existing food additives — the category for natural substances with a long history of use, established when that list was created in 1995. In the EU, steviol glycosides (E960) are an authorised food additive under Regulation (EC) No 1333/2008, covering eleven specific glycosides. In the US, the FDA has not approved whole-leaf stevia or crude stevia extract as a food additive; instead, highly purified steviol glycosides (including rebaudioside A) have reached the market through the GRAS notification route, with the FDA issuing “no questions” letters to notifiers since 2008.
The practical point for a formula: “stevia” is not one single approval status. Whole-leaf or crude extract forms are treated differently from purified steviol glycoside forms in the US in particular, so the exact form and purity used in a Japan-made product should be confirmed against the destination market’s rules rather than assumed from the ingredient name alone.

Sugar alcohols and the laxative-effect question
Sugar alcohols such as erythritol are widely used and generally well tolerated, but the EU and the US both attach a mandatory laxative-effect warning above a defined threshold, while Japan relies on common industry practice rather than one fixed statutory trigger.
Sugar alcohols (polyols) can draw water into the gut at high intake and cause loose stools in some people — a real, well-documented effect, not a safety concern about the ingredient itself. In Japan, erythritol is not on the designated food additive list and is handled as a food rather than as a food additive; in the EU it is an authorised food additive (E968) re-evaluated by the European Food Safety Authority in 2023; and it reached the US market through the GRAS notification route (FDA “no questions” responses from 2001 onward).
| Market | Laxative-warning rule for sugar alcohols |
|---|---|
| EU | A food containing more than 10% added polyols must carry the statement “excessive consumption may produce laxative effects” (Regulation (EU) No 1169/2011, Annex III) |
| US | A specific statement is required once reasonably foreseeable daily intake reaches a defined gram threshold for that sugar alcohol — for example 50 g/day for sorbitol, 20 g/day for mannitol (21 CFR 184.1835; 21 CFR 180.25) |
| Japan | No single fixed statutory percentage or gram threshold found; manufacturers commonly add a voluntary note such as “may cause loose stools in some people” on packs containing sugar alcohols, as common industry practice rather than a uniform legal requirement |
A product formulated to sit just under the EU’s 10% polyol threshold, or Japan’s practical dosing norms, may still cross the US’s per-substance gram threshold at a different serving size — the calculation has to be redone per market, using that market’s own rule, not carried over from another one.
Flavourings: a different starting category in each market
Japan treats flavouring substances as a category of food additive, while the EU regulates them under a separate flavourings regulation and the US relies mainly on an industry-run GRAS process — three different legal starting points for the same bottle of flavouring.
In Japan, natural flavourings are one of the four food additive categories, listed by source material on the Natural Flavouring Original Substance List, and flavouring substances generally are treated as food additives. The EU regulates flavourings under Regulation (EC) No 1334/2008, a dedicated flavourings regulation separate from the general food additives regulation, built around its own positive list of authorised flavouring substances. In the US, the flavour industry has long used its own FEMA GRAS expert-panel process to establish the safety of flavouring substances, alongside FDA’s food additive and GRAS pathways.
None of this changes what a flavouring smells or tastes like — but it changes what evidence a supplier needs to hand over, and how the substance is declared on the Japanese label, when the same flavouring moves from one market’s paperwork to another’s.
Before you ask for a quotation
- Sweetener and flavouring system, by substance name (not just “natural sweetener” or “fruit flavour”)
- Target sweetness profile and any sugar-alcohol content, with the intended serving size
- Countries you will sell in, so the laxative-warning and label wording can be checked per market
- Whether the stevia form (if used) is whole-leaf/crude extract or a purified steviol glycoside
- Any existing label wording for sweeteners or flavourings you want to keep consistent across markets

Frequently asked questions
1. Are sucralose and acesulfame K permitted in Japan?
Yes. Both are designated food additives in Japan — sucralose since 1999, acesulfame K since 2000 — each with its own use standard and compositional specification, alongside their separate EU and US approvals.
2. Is stevia treated the same way in Japan, the EU and the US?
No. Stevia extract has long been on Japan’s existing food additives list. The EU authorises purified steviol glycosides (E960) as a food additive. The US has not approved whole-leaf or crude stevia extract as a food additive; only highly purified steviol glycoside preparations have reached the market, through the GRAS notification route.
3. Do sugar alcohols need a laxative warning on a Japan-made product?
There is no single fixed statutory threshold in Japan the way there is in the EU (10% of added polyols) or the US (a gram-per-day threshold that varies by substance). Many Japanese products carry a voluntary note about possible loose stools as common practice, but the wording and trigger are not standardised by law the way they are in the EU or US.
4. Why would the same sweetener need different labelling in different markets?
Because each market’s food law defines its own trigger and wording. The EU’s polyol warning is percentage-based, the US’s is a gram-per-day threshold that differs by substance, and Japan’s use-category labelling rule (for sweeteners specifically) requires a different label phrase again.
5. Can I use one flavouring system across all markets without changes?
Often the base flavouring compound can be shared, but the regulatory paperwork cannot — Japan treats flavourings as a food additive category, the EU regulates them under a dedicated flavourings regulation, and the US relies mainly on an industry GRAS process. Each requires its own compliance check.
