What is Resistant Dextrin?

Resistant Dextrin is a highly soluble dietary fiber derived from corn or wheat starch, widely utilized in food manufacturing as a low-calorie bulking agent and functional fiber to promote digestive health.

How is Resistant Dextrin made?

Step No. Production Stage Key Action Control Point & Note
1 Raw Material Sourcing Receive and inspect high-purity, food-grade starch (e.g., corn, wheat, or tapioca starch). Verify supplier's Certificate of Analysis (COA). Test for purity, moisture content, and microbial load. Material must be free from contaminants.
2 Acidification Prepare a slurry by mixing starch with water and adding a food-grade acid catalyst (e.g., hydrochloric or citric acid). The starch-to-water ratio and uniform mixing are critical. Precisely control the addition of acid to achieve a target pH level (e.g., 1.5 - 2.5).
3 Pre-Drying The acidified slurry is partially dried to a specific, low moisture content, creating an "acidified starch cake". Achieving the correct intermediate moisture content is crucial for an efficient and controlled pyrolysis reaction in the next step.
4 Pyrolysis / Dextrinization Heat the acidified starch under controlled conditions. The heat and acid cause hydrolysis and subsequent repolymerization, forming new, indigestible glycosidic bonds. This is the most critical step. Strict control of temperature (typically 140-200°C) and reaction time directly determines the dietary fiber content and properties of the final product.
5 Cooling & Re-hydration Rapidly cool the resulting pyrodextrin to halt the chemical reaction. The product is then re-dissolved in water. Proper cooling ensures product consistency. The solution's concentration (Brix level) is monitored during re-hydration.
6 Purification & Refining Treat the solution with enzymes (e.g., amyloglucosidase) to break down remaining digestible sugars, followed by filtration, activated carbon treatment, and/or ion-exchange chromatography. Enzyme activity and reaction time must be monitored. This stage removes mono- and disaccharides, color, and off-flavors, increasing the relative fiber content. Purity is often verified by HPLC analysis.
7 Spray Drying Atomize the purified resistant dextrin solution into a chamber with hot air, evaporating the water and forming a fine powder. Control of inlet/outlet air temperature and feed rate is essential to achieve the target final moisture content (<5%) and desired powder density without causing heat damage or discoloration.
8 Sieving & Packaging Sieve the final powder for uniform particle size and package it into sealed, multi-layer, food-grade bags. A metal detector is a critical final control point before packaging. Package integrity is checked to protect the product from moisture and contamination during storage and transport.

Mechanism of action:

ParameterResistant Dextrin
Functional CategorySoluble Prebiotic Fiber; Bulking Agent; Texturizer; Sugar Reduction Aid
Key IngredientsResistant Dextrin (a non-digestible glucose polymer derived from starch)
Mechanism of ActionResists hydrolysis by enzymes in the upper gastrointestinal tract, passing intact to the large intestine; acts as a prebiotic substrate for fermentation by beneficial gut microbiota; provides non-viscous soluble solids that contribute bulk and mouthfeel without significantly increasing viscosity or water activity; exhibits a low glycemic response as it is not absorbed as simple sugars.
Application Effect in ProductIncreases dietary fiber content for nutritional claims; enables significant sugar and calorie reduction by replacing sugar's bulk; improves body and mouthfeel in reduced-sugar beverages, baked goods, and dairy products; maintains a clean flavor profile and high processing stability (heat, acid); helps control moisture and extend shelf life by lowering water activity.


Comparison:

Product Name Category/Type Key Features Strengths (vs peers) Weaknesses (vs peers) Best Use Cases Why Choose
Resistant Dextrin Soluble Prebiotic Fiber (from starch) High solubility, low viscosity, heat and acid stable, neutral taste. Exceptional process tolerance (baking, pasteurization); very high digestive tolerance; low water activity. Less potent prebiotic effect per gram compared to inulin/FOS. Beverages, baked goods, dairy products, processed foods requiring fiber fortification without altering texture. For applications needing extreme heat/pH stability and high digestive tolerance with minimal sensory impact.
Inulin / FOS Soluble Prebiotic Fiber (from chicory, agave) Varies in sweetness and chain length, can form gels, strong prebiotic. Potent and well-studied prebiotic effect; can provide sweetness and fat-mimicking texture. Lower digestive tolerance (gas, bloating at lower doses); less stable in high heat and low pH conditions. Yogurts, protein bars, supplements, low-sugar products where some sweetness is beneficial. When the primary goal is a strong prebiotic benefit and its textural/sweetening properties are desired.
Soluble Corn Fiber (SCF) Soluble Prebiotic Fiber (from corn starch) High solubility, high digestive tolerance, heat and acid stable. Excellent digestive tolerance; some types may increase calcium absorption; clean taste profile. Functionally very similar to resistant dextrin, making differentiation difficult. Keto-friendly products, beverages, nutrition bars, dairy, cereals. For a high-tolerance, corn-based fiber, especially when seeking claims related to calcium absorption.
Polydextrose Synthetic Soluble Fiber Low calorie (1 kcal/g), acts as a bulking agent, high solubility, low glycemic response. Excellent bulking agent for sugar replacement with very low caloric contribution; provides good mouthfeel. Often perceived as less "natural" by consumers; weaker prebiotic activity. Sugar-free confectionery, ice cream, baked goods, meal replacement shakes. For significant sugar and calorie reduction while maintaining product bulk and texture.
Acacia Gum (Gum Arabic) Natural Soluble Prebiotic Fiber (from tree sap) Excellent emulsifier, low viscosity, high solubility, very slow fermentation. Superior emulsifying properties; extremely well-tolerated due to slow fermentation; certified low-FODMAP. Higher cost and potential supply chain volatility; provides less bulk than polydextrose. Beverages (emulsifying oils/flavors), coatings, supplements for sensitive individuals. When an emulsifier and fiber are needed in one ingredient, or for a very gentle, slowly fermented fiber.
Partially Hydrolyzed Guar Gum (PHGG) Natural Soluble Prebiotic Fiber (from guar bean) Non-viscous, tasteless, odorless, dissolves completely clear. Clinically supported for gut regularity (IBS); extremely high tolerance; does not thicken liquids. Offers minimal textural benefits (bulking, gelling) in food formulation. Clear beverages, tube feeding formulas, medical foods, supplements for digestive health. For targeted gut health benefits (especially regularity) without impacting product viscosity or clarity.
