Isomaltulose
Isomaltulose suppliers and sourcing guide
Isomaltulose is a disaccharide of glucose and fructose, like sucrose, but with the two sugars joined by a different bond. It is made from beet or cane sucrose using a sucrose isomerase enzyme, then purified and crystallized, usually as a monohydrate. It has about half the sweetness of sucrose and is sold as a crystalline powder for beverages, drink mixes, bars and confectionery, and is also the starting material for isomalt.

Forms and grades of isomaltulose
Suppliers sell different products under the same name. Specify the one you need.
Crystalline
Monohydrate crystals for beverages, powdered drink mixes, cereals and confectionery.
Fine powder
Milled grade for dry blends and coatings.
Dried syrup
Spray-dried isomaltulose syrup, a form covered by a separate GRAS notice.
Blends
Isomaltulose blended with high-intensity sweeteners or other carbohydrates in drink and bar premixes.
What to check on the COA
Compare each result with your own specification when the lot arrives.
- Assay (HPLC)
- Isomaltulose on a dry basis by HPLC, with trehalulose, sucrose, glucose, fructose and isomaltose reported.
- Water (Karl Fischer)
- Water by Karl Fischer, judged against the range for the monohydrate.
- Color and ash
- Solution color and ash as purity checks.
- Heavy metals
- Lead and other metals by ICP-MS against the supplier limit.
- Microbiology
- Total plate count, yeast and mold, and pathogens.
Storage, lots and expiry
Storage and shelf life
Store isomaltulose sealed in a cool, dry area; it is relatively non-hygroscopic but powders can cake if left open in humid conditions. Shelf life is set by the supplier's specification, with retest of water and micro for aged stock.
Lots and expiry dates
Record the assay and the minor sugar profile for each lot, especially when switching between crystalline isomaltulose and dried syrup, which differ in composition. Note the sucrose source (beet or cane) if your label or certifications depend on it.
Regulatory status
Facts from regulators and standards bodies, each linked to its source.
