Isomaltulose Overview

What Is Isomaltulose?
Isomaltulose is a carbohydrate that works as a sweetener. Scientists call it a disaccharide. This means it has two simple sugars: glucose and fructose. These sugars are joined by an α(1→6) glycosidic bond. Regular sugar uses an α(1→2) bond instead. Isomaltulose’s formula is C12H22O11. It has eight special points called stereocenters. When water is added, it becomes a hydrate and gets heavier. Food makers use isomaltulose because it tastes sweet and gives steady energy.
Natural Sources
Honey is the main natural source of isomaltulose. Bees make honey, and it has this slow-release sugar. Sugar cane juice also has a little isomaltulose. These foods have isomaltulose in their natural form. No other foods have much of this sweetener.
Isomaltulose vs. Sugar
Isomaltulose and table sugar both have glucose and fructose. But their bonds are not the same. Isomaltulose’s α-1,6 bond is harder to break down. This makes it digest slower. Its glycemic index is 32, which is lower than sucrose’s 65. Eating isomaltulose causes blood sugar and insulin to rise slowly. Studies show isomaltulose gives a 20% lower blood sugar peak. It also causes a 55% lower insulin response than sucrose. This helps people control blood sugar, especially with diabetes.
Tip: Picking isomaltulose as a sweetener can help keep blood sugar steady and support health.
Palatinose Explained
Palatinose is another name for isomaltulose. Both names mean the same thing. Palatinose is made from glucose and fructose joined by an α-1,6 bond. This bond makes palatinose digest slowly and give steady energy. Palatinose is fully digestible and gives 4 kcal per gram. It does not feed bad mouth bacteria, so it helps teeth. Food companies use palatinose for its health benefits and balanced sweetness.
Aspect | Sucrose | |
|---|---|---|
Composition | Disaccharide of glucose and fructose | Disaccharide of glucose and fructose |
Glycosidic bond | α-1,6 linkage | α-1,2 linkage |
Digestion rate | Slower hydrolysis in small intestine | Rapid hydrolysis |
Glycemic index (GI) | Lower (slow glucose release) | Higher (fast glucose release) |
Tooth friendliness | Not fermented by oral bacteria, reduces acid | Fermented by oral bacteria, acid |
Metabolic effect | Low and balanced blood glucose and insulin | Rapid blood glucose and insulin spikes |
Sweetness | About 50% of sucrose | Standard sweetness |
Source | Found in honey, sugar cane juice, made from sucrose | Natural sugar in many plants |
Health Benefits

Low-Glycemic Sweetener
Palatinose is a sweetener with a low glycemic index. Scientists use glycemic index to see how fast carbs raise blood sugar. Palatinose has a glycemic index of 32, which is much lower than regular sugar. This means it raises blood sugar more slowly.
Studies show palatinose can lower blood sugar after meals by 20%–52% and insulin by 30%–50% compared to sucrose or maltodextrin.
These effects are seen in both healthy people and those with diabetes.
Research shows palatinose is absorbed more slowly and the liver takes up more glucose.
Groups like EFSA and FDA say palatinose is safe and good for teeth.
Picking a low-glycemic sweetener like palatinose helps keep blood sugar steady and supports health.
Blood Sugar Control
Palatinose helps control blood sugar. Its α-1,6 glycosidic bond makes it digest slowly. This causes glucose to enter the blood gradually and gives a gentle rise in blood sugar.
Both healthy and diabetic people have lower blood sugar after eating palatinose than sucrose.
A study found plasma glucose drops by about 7.99 mg/dL at 60 minutes after eating.
People with diabetes who control their blood sugar well see even better results.
The effect is not huge, but palatinose is still a good choice for managing blood sugar, especially for diabetes.
Many studies show palatinose gives a longer and lower blood sugar response than sucrose.
Slow digestion means the pancreas makes less insulin and fewer incretins, which help release insulin.
Studies include adults with diabetes, people with trouble handling glucose, and others with health problems.
Palatinose leads to lower peaks in blood sugar and insulin, which helps control blood sugar.
Gut Health
Palatinose helps the gut by acting as a prebiotic.
Lab studies show palatinose helps good bacteria grow and boosts short chain fatty acids like acetic and butyric acids.
In a lab model of the human colon, palatinose lowers the Firmicutes to Bacteroidetes ratio, which helps balance gut bacteria.
Rat studies show palatinose increases good bacteria like Faecalibacterium and Phascolarctobacterium and lowers bad bacteria.
Tests show more short chain fatty acids and better bile acid profiles.
Rats eating palatinose have lower body weight, eat less, handle glucose better, and have lower blood fats.
Clinical trials show palatinose is easy to digest and safe.
During exercise, 50 g of palatinose does not upset the stomach or slow down how fast the stomach empties compared to maltodextrin.
People do not report stomach problems, so palatinose is safe for digestion.
Dental Health
Palatinose is good for teeth and helps dental health.
Tests on chocolate with palatinose show it does not lower plaque pH below the level that causes tooth decay.
The product got the ‘Happy Tooth’ seal, showing it is safe for teeth.
Studies show palatinose is barely broken down by mouth bacteria and stops the formation of glucans that cause cavities.
Animal studies show palatinose is fully digested and absorbed in the small intestine, and it breaks down slower than sucrose.
Palatinose does not make dental plaque more acidic, so it is a good sucrose replacement for teeth.
When compared to other sweeteners, palatinose changes dental plaque bacteria only a little and causes just a short drop in saliva pH.
It is absorbed slower than sucrose and is fully digested, so people with diabetes like it.
Palatinose is good for teeth but not totally safe from cavities, so brushing and flossing are still important.
Energy Release
Palatinose gives slow and steady energy.
The sucrase-isomaltase enzyme breaks down palatinose 4.5 times slower than sucrose.
Because it digests slowly, palatinose goes farther in the small intestine, changes hormone levels, and keeps carbs coming into the blood longer.
Blood sugar stays up longer after eating palatinose, showing it gives steady energy.
Palatinose is fully digested and is a steady energy source.
Athletes get steady energy from palatinose.
In a study, male athletes who ate palatinose before running used carbs for energy longer.
Their top power was higher after eating palatinose.
Other studies show better cycling times and more power after long exercise with palatinose.
Aspect | Effect of Palatinose Compared to Sucrose or Maltodextrin | Notes and Variability |
|---|---|---|
Postprandial Blood Sugar Levels | Steady energy supply | |
Insulin and GIP Concentrations | Lower insulin and GIP after eating | Stops high insulin |
Substrate Utilization | Sometimes more fat burned | Depends on exercise |
Endurance Performance | Better cycling times and more power | Results differ |
Gastrointestinal Tolerance | Usually good and easy to handle | Depends on dose |
Palatinose is easy to digest and gives steady energy for athletes and active people.
