What is Isomaltooligosaccharide (IMO)?

Isomaltooligosaccharide (IMO) is a mildly sweet, digestion-resistant carbohydrate mixture, manufactured from starch, that is widely used in foods as a low-calorie prebiotic fiber and bulking agent.

How is Isomaltooligosaccharide (IMO) made?

Step No. Production Stage Key Action Control Point & Note
1 Starch Liquefaction Prepare a slurry of food-grade starch (e.g., corn, tapioca) and water. Add α-amylase enzyme and heat to break down long starch molecules into shorter dextrins. Control of temperature, pH, and enzyme dosage is critical. The reaction is monitored by testing the Dextrose Equivalent (DE) value to ensure proper starch breakdown.
2 Saccharification Cool the liquefied mash and add a second enzyme, such as glucoamylase, to convert the dextrins into a high-glucose syrup. The process requires strict control over temperature and reaction time to maximize the conversion of dextrins to glucose, the essential substrate for IMO synthesis.
3 Transglucosylation Introduce the key enzyme, transglucosidase (α-glucosidase), to the glucose-rich syrup. This enzyme re-links glucose molecules with α-1,6 glycosidic bonds, forming isomaltooligosaccharides. This is the most critical stage. The final IMO content is determined by precise control of substrate concentration (Brix), enzyme dosage, temperature, and reaction time.
4 Enzyme Deactivation Rapidly heat the syrup to a high temperature (e.g., 95-105°C) to permanently denature and inactivate all enzymes, halting the reaction. The syrup must reach and be held at the target deactivation temperature for a specific duration to guarantee complete cessation of all enzymatic activity.
5 Decolorization Pass the crude IMO syrup through columns containing activated carbon to adsorb color compounds and other organic impurities. Monitor the flow rate and syrup temperature. The color of the outlet syrup is regularly checked against a standard to ensure effectiveness and determine when carbon needs changing.
6 Ion Exchange Pump the decolorized syrup through cation and anion exchange resin beds to remove mineral salts and charged impurities, improving clarity and taste. The electrical conductivity of the syrup is continuously monitored at the outlet. A rise in conductivity indicates the resins are saturated and require regeneration.
7 Evaporation Remove excess water from the purified syrup using a multi-effect evaporator under vacuum to increase the solids content. The primary control is achieving the target final Brix value (e.g., 75-80%). Using a vacuum prevents caramelization and heat damage to the product.
8 Spray Drying (Optional) If producing a powder, the concentrated syrup is atomized into a hot air stream, which rapidly evaporates the remaining water. This step is only for powder IMO. Control of inlet/outlet air temperature and feed pressure is crucial to achieve the target moisture content and particle size.
9 Final Packaging The final product (syrup or powder) is filtered one last time and then filled into clean, food-grade containers (e.g., drums, totes, bags). A metal detector is a critical control point before packaging. Ensure proper sealing, weight verification, and correct labeling with batch number and expiration date.

Applications & Usage

Common Applications:

Beverages
bars
cereal
candy
functional foods

Mechanism of action:

Parameter Isomaltooligosaccharide (IMO)
Functional Category Prebiotic Fiber; Sweetener; Humectant; Bulking Agent.
Key Ingredients A mixture of α-(1→6) and α-(1→4) linked glucose oligomers, including isomaltose, panose, isomaltotriose, and isomaltotetraose.
Mechanism of Action Resists digestion by upper gastrointestinal enzymes due to α-(1→6) glycosidic bonds. Serves as a fermentable substrate for beneficial gut microbiota (e.g., Bifidobacteria, Lactobacilli), promoting their growth and the production of short-chain fatty acids (SCFAs). Provides mild sweetness (approx. 50-60% of sucrose) and high water-binding capacity.
Application Effect in Product Adds dietary fiber content; reduces sugar content while maintaining mild sweetness and desirable mouthfeel; increases moisture retention, improving texture and extending shelf life in baked goods and bars; provides bulk and viscosity control in syrups and beverages.


Comparison:

Product Name Category/Type Key Features Strengths (vs peers) Weaknesses (vs peers) Best Use Cases Why Choose
Isomaltooligosaccharide (IMO) Prebiotic Fiber / Functional Sweetener Mixture of glucose oligomers; mildly sweet (50-60% of sugar); good heat and acid stability. Excellent binding properties for bars; good texture and mouthfeel; very stable during processing. Some forms are partially digestible, raising blood sugar more than other fibers; prebiotic effect can be variable. Protein bars, nutrition bars, baked goods, sugar-reduced syrups and beverages. For superior binding and texture in bars and baked goods where structure is critical.
Fructooligosaccharides (FOS) Prebiotic Fiber / Sweetener Short-chain fructose polymers; clean, mild sweetness; often derived from chicory root or cane sugar. Strong, well-documented prebiotic effects at low doses; enhances mineral absorption. High potential for causing gas, bloating, and digestive discomfort in sensitive individuals. Yogurts, dairy products, supplements, infant nutrition, beverages. For a potent and scientifically-backed prebiotic effect, especially in supplements and dairy.
Soluble Corn Fiber (SCF) Soluble Dietary Fiber Non-digestible glucose polymer; minimal sweetness; high solubility and process stability. Extremely high digestive tolerance (very low gas/bloating); excellent stability in heat and acid. Less potent prebiotic activity compared to FOS or XOS; provides little to no sweetness. High-fiber beverages, meal replacement shakes, baked goods, products for sensitive stomachs. When maximum digestive tolerance and processing durability are the highest priorities.
Chicory Root Fiber (Inulin) Prebiotic Fiber / Fat Replacer Long-chain fructose polymers; forms a gel with water; provides creamy texture; minimal sweetness. Excellent fat mimetic, improving mouthfeel in low-fat products; strong prebiotic activity. Can cause significant gas/bloating similar to FOS; can create undesirable gel textures if not used correctly. Low-fat yogurts, ice cream, spreads, dairy applications, fiber fortification in baked goods. To add fiber while simultaneously improving texture and replacing fat, especially in creamy foods.
Xylooligosaccharides (XOS) Prebiotic Fiber Oligomers of xylose from plant sources like corn cobs; not sweet. Clinically shown to be effective as a prebiotic at very low doses (1-2g), minimizing side effects. Less common and can be more expensive; provides minimal bulk or functional texture. Concentrated prebiotic supplements, functional foods where only a small ingredient addition is desired. For a highly potent prebiotic effect at a very low dosage, minimizing calories and digestive risk.
Polydextrose Soluble Fiber / Bulking Agent Synthetic polymer of glucose; provides no sweetness but adds bulk and mouthfeel; low calorie. Excellent bulking agent for sugar reduction; highly stable; high digestive tolerance. Lacks the strong, specific prebiotic benefits of FOS or XOS; is a synthetic ingredient. Sugar-free candies, baked goods, frozen desserts, beverages, as a bulking agent. When the primary goal is to replace the bulk and texture of sugar with a low-calorie, stable fiber.
