Isomalt
Isomalt is a disaccharide sugar alcohol designed as a sucrose replacement with exceptional thermal and crystallisation stability, used widely in hard-boiled confectionery and pulled-sugar showpieces.
It is an equimolar mixture of two stereoisomers, 6-O-alpha-D-glucopyranosyl-D-sorbitol (GPS) and 1-O-alpha-D-glucopyranosyl-D-mannitol (GPM), with formula C₁₂H₂₄O₁₁ and CAS 64519-82-0. The blend delivers 45 to 65 percent of the sweetness of sucrose without aftertaste.
We source bulk Isomalt from top China manufacturers for our partners, working with several of them. The manufacturers are mostly in Guangdong, Shandong and Jiangsu. For this ingredient the minimum order is 500 kg and a 20-foot container takes 20 MT, and a smaller requirement can ship in a combined container with other ingredients.
Please send the grade you need, the volume and your destination port, and we will come back with a solution and a price.

Common Markets Grades
Isomalt is a free-flowing white crystalline powder at 98 percent minimum assay.
Standard granulations cover medium-crystal for hard candy and lollipops, fine for pan coating and tabletting, and powdered milled for chocolate, fondant, and sachet formats.
Specialty grades include extra-low-moisture material for sugar-art and isomalt-pulling applications and agglomerated grades for instantizing in beverage mixes.
Pharmaceutical-grade material complies with USP-NF and Ph. Eur. monographs. Food-grade material meets FCC and JECFA specifications.
Applications
- Sugar-free hard candies, lollipops, and lozenges where high cooking temperatures and crystallisation control are required

How We Help Source Isomalt
Direct Factory Sourcing
We run the whole process: selecting the manufacturer from the top Chinese food ingredient producers, negotiating the price, verifying quality, and coordinating the logistics. You deal with us instead of with several factories at once.
Original Packaging and Documents from the Manufacturer
The manufacturer sends your Isomalt out of its own factory in the original packing, through to your destination port. The COA, COO, MSDS, TDS and any certifications reach you from the manufacturer as well.
Free Samples and Lead Time
We send 100 to 500 g free for your own laboratory to test and you cover only the courier, usually within 2 to 3 working days. ETD is usually within 7 to 15 days once the order is confirmed, and we check that date against the factory's own manufacturing schedule before we give it to you.
Combined Shipment
We can load Isomalt together with other ingredients such as Stevia, Erythritol and Maltitol into one 20' FCL. If your quantity is small, we can also ship LCL.
Regulatory Status
Isomalt holds broad regulatory approval as a food additive.
In the European Union it carries E number E953, with no overall maximum limit in the additives regulation though it is subject to the general quantum satis principle. EU labelling requires the statement excessive consumption may produce laxative effects when a serving delivers more than 10 grams of polyol.
The U.S. Food and Drug Administration accepted isomalt as GRAS in 1990 for use as a nutritive sweetener and bulking agent. The agency has accepted a labelling caloric value of 2.0 kcal per gram.
JECFA has evaluated isomalt as safe for food use. Pharmacopoeial monographs appear in USP-NF and Ph. Eur.
The substance is Halal and Kosher certifiable and is not a recognised food allergen.
Manufacturing Process
Isomalt is produced from sucrose in a two-step enzymatic and catalytic process.
In the first step refined sucrose is converted to isomaltulose (palatinose) by the enzyme sucrose isomerase, produced by Protaminobacter rubrum or related bacteria. The enzymatic rearrangement converts the alpha-1,2 glycosidic bond of sucrose into an alpha-1,6 bond between glucose and fructose, yielding isomaltulose.
In the second step isomaltulose is catalytically hydrogenated under hydrogen pressure over a Raney nickel catalyst. The fructose moiety is reduced and yields the two stereoisomers GPS and GPM in approximately equimolar proportion, producing the characteristic isomalt mixture.
The product solution is filtered, demineralized through ion-exchange resins, decolorised on activated carbon, and concentrated under vacuum. Controlled cooling crystallisation gives the crystalline product, which is centrifuged, dried, and milled.
