Isomaltulose vs Isomalt Overview
What Is Isomaltulose?
Isomaltulose is found in foods that help you get steady energy. It is a kind of sugar called a disaccharide. Isomaltulose comes from sucrose, which is table sugar. Scientists use enzymes to change sucrose into isomaltulose. Isomaltulose has glucose and fructose joined by a special bond called α-1,6 glycosidic. This bond makes your body break down isomaltulose slowly. You get energy over time and your blood sugar does not rise quickly.
Isomaltulose is used in breakfast cereals, sports drinks, and baby food. You also see it in meal replacements and nutrition products. It helps you keep your blood sugar steady and gives you energy that lasts. Isomaltulose is safe for most people, even babies. You can find it in small amounts in honey and sugar cane juice.
Tip: If you want a sugar that does not make your blood sugar go up fast, isomaltulose is a good pick.
What Is Isomalt?
Isomalt is a sugar alcohol, also called a polyol. Isomalt is made by hydrogenating isomaltulose. This process changes isomaltulose and makes isomalt harder to digest. Isomalt is not a reducing sugar. You find isomalt in sugar-free candies, chewing gum, and baked goods. It helps lower the sugar in foods but keeps them sweet and tasty.
Isomalt does not make your blood sugar go up much. Your body takes in isomalt slowly, and it does not cause tooth decay. You use isomalt to replace sugar in foods for people who need less sugar.
Here is a table to help you compare Isomaltulose vs Isomalt:
Aspect | Isomaltulose | Isomalt |
|---|---|---|
Classification | Disaccharide | Disaccharide polyol (sugar alcohol) |
Origin | Derived from sucrose by enzymatic isomerization | Produced by hydrogenation of isomaltulose |
Chemical Structure | Glucose and fructose linked by α-1,6 glycosidic bond | Hydrogenated derivative of isomaltulose |
Digestibility | Digestible to glucose and fructose | Minimally digestible carbohydrate |
Usage | Functional alternative sugar | Sugar replacer in sugar-free products |
Reducing Sugar | Yes (due to ring-opening fructose) | No |
Isomalt comes from isomaltulose, but they do different things in food. Isomaltulose gives you slow energy and helps control blood sugar. Isomalt lets you eat sweet foods without extra sugar or tooth problems. When you read food labels, knowing about Isomaltulose vs Isomalt helps you pick what is best for you.
Structure and Production
Chemical Structure
You can spot big differences in the chemical structures of isomaltulose and isomalt.
Isomaltulose is a reducing disaccharide. It has glucose and fructose joined by an α-1,6 glycosidic bond (6-O-α-D-glucopyranosyl-D-fructofuranose).
This α-1,6 bond is not like the α-1,2 bond in sucrose. Because of this, isomaltulose is a reducing sugar, but sucrose is not.
The α-1,6 bond makes isomaltulose more stable in acid and slower to digest.
Isomaltulose tastes less sweet than sucrose, about half as sweet. It does not break down in acid and does not cause tooth decay.
The fructose part in isomaltulose can open up and show a carbonyl group. This makes isomaltulose a reducing sugar and lets it brown in foods.
These things give isomaltulose a lower glycemic index and help it stay stable in sour foods.
Isomalt has a different structure. It is a sugar alcohol made from two kinds of disaccharides: 1-O-α-D-glucopyranosido-D-mannitol (1,1-GPM) and 6-O-α-D-glucopyranosido-D-sorbitol (1,6-GPS). Each molecule has glucose joined to mannitol or sorbitol. When you break down isomalt, you get 50% glucose, 25% mannitol, and 25% sorbitol. This mix helps isomalt stay stable in wet air and not form crystals. Isomalt stays clear when it gets hot and does not turn brown easily. These features make isomalt great for sugar-free candies and baked treats.
Note: The special structures of isomaltulose and isomalt explain why they act so differently in foods. Knowing these differences helps you choose better when looking at Isomaltulose vs Isomalt.
How They Are Made
Here are the steps to make isomaltulose and isomalt:
Producers start with sucrose from sugar cane or sugar beets.
To make isomaltulose, they use special enzymes called sucrose isomerase (SIase). These enzymes break the α-1,2 bond in sucrose and change it to an α-1,6 bond, making isomaltulose.
Factories use two main ways for this step:
Microbial conversion: They use bacteria that make SIase to turn sucrose into isomaltulose.
Enzymatic conversion: They use pure SIase enzymes to do the same thing.
Some companies use genetic engineering to help bacteria make more SIase and work faster.
After making isomaltulose, they clean it so it is ready for food.
To make isomalt, they take the isomaltulose and hydrogenate it. This step adds hydrogen atoms and turns the sugar into a sugar alcohol.
The result is a mix of two sugar alcohols: 1,1-GPM and 1,6-GPS. This mix gives isomalt its special uses in foods.
You can see that making isomalt starts with making isomaltulose first. This step-by-step process makes sure both ingredients are safe and pure for your food.
Functional Properties
Sweetness and Taste
Isomaltulose tastes less sweet than regular sugar. It is about half as sweet as sucrose. The flavor is mild and not strong. If you want a gentle sweet taste, isomaltulose is a good pick. Isomalt tastes almost as sweet as sucrose. Foods with isomalt taste like foods with sugar. You will not notice much difference in sweetness with isomalt. Candies and baked goods made with isomalt taste sweet like sugar.
If you want food to taste as sweet as sugar, use isomalt. If you want a lighter sweet taste, choose isomaltulose.
Stability and Texture
Isomaltulose and isomalt both stay stable when heated or used in sour foods. Isomalt melts at a higher temperature, between 145°C and 150°C. It does not turn brown easily, so it works well for baking and candy. Isomalt does not soak up much water, so foods stay crisp and fresh. Isomaltulose melts at a lower temperature, around 123–124°C. It still works well in sour drinks and foods. It stays stable in strong acid for at least a day.
Isomalt gives baked goods a soft and moist feel, like sugar does. Muffins with isomalt are not hard or dry. Isomalt helps cakes and cookies keep the right texture. Polyols like isomalt can make starches thicken at higher temperatures. This changes how food feels when you eat it. There is not much known about how isomaltulose changes texture. It does not seem to change texture much in most foods.
Food Applications
Isomaltulose and isomalt are used in different foods because of their special features. Isomaltulose is found in sports drinks, cereals, and nutrition bars. It has a low glycemic index and is good for teeth. People who want steady energy or better dental health like isomaltulose. You might choose foods with isomaltulose if you care about blood sugar or want to avoid cavities.
Isomalt is used in sugar-free candies, chocolates, gum, and cake decorations. It does not melt or get sticky in heat or humidity. You can make clear and stable sugar shapes with isomalt.

Health and Nutrition
Blood Sugar Effects
You may wonder how these sweeteners change your blood sugar. Isomaltulose gives you slow, steady energy. It does not make your blood sugar jump fast. Studies show isomaltulose raises blood sugar less than regular sugar. Your body takes in isomaltulose slowly, so energy lasts longer. Insulin does not go up as much, so you avoid big spikes.
The insulin peak after eating isomaltulose is much lower than with sucrose.
Isomaltulose helps keep blood sugar steady when you exercise.
Isomalt has a low glycemic index too. But scientists have not tested it against isomaltulose in studies. You can see how they compare in this table:
Sweetener | Glycemic Index (GI) | Notes on Blood Glucose Impact |
|---|---|---|
Isomaltulose | 32 | Low GI; keeps blood sugar higher during exercise |
Maltodextrin | 90-100 | High GI; makes blood sugar rise quickly |
Dental Health
You want to keep your teeth healthy, so sweetener choice matters. Isomaltulose does not cause cavities. Studies show rinsing with isomaltulose keeps mouth pH safe for teeth. Sucrose drops pH and can hurt enamel, but isomaltulose does not. The FDA says isomaltulose does not cause tooth decay.
Isomalt also helps protect teeth. New studies show isomalt in mouth rinse can stop enamel loss. It may even help fix early tooth damage. Isomalt works with fluoride to make teeth stronger. It does not feed bad bacteria, so you can eat sweet foods without worry.
Tip: To keep your teeth safe, both isomaltulose and isomalt are good picks.
Calorie Content
You might want to know how many calories these sweeteners add. Isomaltulose gives the same energy as regular sugar. Isomalt gives about half the calories. Isomaltulose is fully used by your body, so it gives you energy. Isomalt is only partly taken in and is fermented in your gut, so it has fewer calories.
Substance | Mean Caloric Value (kcal/g) |
