Isomalt vs sorbitol
in numbers
Typical values from published polyol data; isomalt values from the NewTrend technical data sheet where applicable.
| Property | Isomalt (E953) | Sorbitol (E420) |
|---|---|---|
| Sweetness vs sucrose | 0.45 to 0.6 | 0.6 |
| Energy (EU labelling) | 2.4 kcal/g as a polyol; about 2 measured | 2.4 kcal/g |
| Glycaemic index | 9 | About 9 |
| Moisture pick-up (hygroscopicity) | Very low | High |
| Melting point | 145 to 150 °C | About 95 °C |
| Cooling effect | None | Mild cooling |
| Digestive tolerance | Medium to high | Lowest |
| Tooth-friendly | Yes | Yes |
| Clear hard candy | Yes, the standard base | No |
| Best for | Hard candy, lozenges, tablets, sugar art | Chewing gum, sugar-free syrups, humectant |
// Verdict
Which one
to use
01
Reach for isomalt when
You need a clear, hard, non-sticky product, a diabetic-friendly claim, a direct-compression excipient or decorations that survive humidity.
02
Reach for sorbitol when
Sorbitol is inexpensive and a good humectant, but it is very hygroscopic and melts at a low temperature, so hard candy made with it turns sticky and soft. Isomalt resists moisture and stays glassy. Sorbitol also has the lowest laxative threshold of the common polyols.
03
Use both when
Many sugar-free ranges use isomalt for the hard formats and sorbitol where its own strengths apply. Isomalt India can suggest a blend for your product.
// Questions buyers ask
Frequently asked
Is isomalt better than sorbitol?
Neither is better in every case. Isomalt is the better base for clear hard candy, lozenges, tablets and sugar art and has a lower glycaemic index. Sorbitol suits chewing gum, sugar-free syrups, humectant.
Can I replace sorbitol with isomalt one-for-one?
By weight, yes for bulk; isomalt is less sweet than sorbitol (0.45 to 0.6 vs 0.6 times sucrose), so add a little high-intensity sweetener to match sweetness.
Which has fewer calories, isomalt or sorbitol?
Isomalt is about 2 kcal/g measured and labelled at 2.4 kcal/g as a polyol; sorbitol is 2.4 kcal/g.
