Sucralose Guide — Use Standard and Weighing Control, from a Real Import Case

What sucralose is

Sucralose is a high-intensity sweetener in which some hydroxyl groups of sucrose are replaced by chlorine. It appears as No. 236 in the designated additives list, as “sucralose (also known as trichlorogalactosucrose)”. J-STAGE returns 168 papers, 56 of them from 2020 onward.

Aggregating Foods with Function Claims notifications by functional ingredient name, sucralose accounts for zero. That is not a judgment on the material but a statement of its role: sucralose does not carry the claim, it carries the sweetness profile while sugar comes out. The claim is carried by a different functional ingredient.

There is a use standard — and a real violation case

Some designated additives carry an upper limit on use by food category (a use standard), and sucralose is one of them. Exceeding it is a violation of the Food Sanitation Act.

The Ministry of Health, Labour and Welfare’s published record of import violations carries a specific case.

• Item — other prepared fruit (PLUM AND STRAWBERRY / PLUM AND MANGO / PLUM AND GRAPES; three entries)
• Manufacturer — FUJIAN JISAN AGRICULTURAL DEVELOPMENT CO., LTD. (People’s Republic of China)
• Violation — non-conformity with the use standard. Sucralose detected at 4.2 g/kg, 3.8 g/kg and 4.5 g/kg
• Basis — Food Sanitation Act, Article 13(2)
• Where and when — Osaka, 8 July 2025. Found on voluntary inspection; the measure taken was return of the shipment

The notable part is the published cause: “inadequate control when weighing the additive”. Not a quality problem with the raw material, but weighing control on the production floor. One of the three entries also cites non-conformity for sulfur dioxide.

This is a structural risk common to high-intensity sweeteners. Sucralose is hundreds of times sweeter than sucrose, so the charged quantity is very small and a slight weighing error becomes an over-limit result directly. “We bought the right material” does not prevent it.

What matters in sourcing and production

• Confirm the use standard — the limit depends on which food category the finished product falls into. Check before formulating
• Weighing accuracy — as the case above shows, this is the largest practical risk. For small charges, consider a premix (diluted grade); the error is an order of magnitude smaller than weighing the neat material
• Blend uniformity — with a small charge, inadequate mixing leaves concentration variation within the product. Within-lot variation can also produce an over-limit result
• Combination with other sweeteners — used alone it leaves a lingering note, so combining with erythritol and others to balance the profile is standard
• Country and site of manufacture — the case above came down to site control at an imported-goods manufacturer. Confirm per site when changing supplier

FONTIA supplies sucralose (CAS 56038-13-2). The specification includes the compendial purity test items.

What to confirm on the specification

• Assay — compendial compliance, and whether the material is neat or diluted
• Purity tests — the compendial items, including heavy metals and methanol
• Particle size — feeds directly into blend uniformity; particularly important at small charges
• Site of manufacture — country and site, which bears on the import inspection record
• COA per lot — confirm availability and format even for a commodity item

Erythritol is the usual partner for balancing the sweetness profile. Note that erythritol is not on the designated additives list and is handled as a food raw material — a different regulatory category from sucralose. Ingredient labelling and the specification format both change with it, which matters in projects that switch several sweeteners at once. See the erythritol guide for details.
