What is Dextrin? Types and Industrial Uses Explained

1. Introduction to Dextrin

Dextrin is a group of low-molecular-weight carbohydrates produced by the hydrolysis of starch. It’s widely used across multiple industries for its adhesive and stabilizing properties. According to ScienceDirect, dextrin's water-solubility and viscosity make it valuable in both food-grade and technical applications.

2. Types of Dextrin

Dextrins are generally categorized based on their production process and application:

• White Dextrin: Mildly roasted starch; mostly used in food.

• Yellow Dextrin: Heated in acidic condition; ideal for adhesives and binders.

• British Gum: Similar to yellow dextrin but used in textiles.

These types vary in solubility and binding strength, making each suitable for different industrial applications.

3. Applications Across Industries

Dextrin is a multi-industry functional ingredient:

• Textile: As a finishing agent or stiffener.

• Paper: Improves binding and printability.

• Mining: Used as a frothing agent in flotation.

• Packaging: Binders in corrugated box adhesives.

Each application demands a specific dextrin variant. 

4. Dextrin in Food and Pharmaceuticals

Food-grade dextrin is widely used as a fiber supplement, thickener, and stabilizer. It helps improve texture and shelf stability in:

• Baked goods

• Processed meat

• Instant sauces and soups

In pharmaceuticals, dextrin is used as a tablet binder, disintegrant, and encapsulation material. PubMed research confirms dextrin’s safety profile and compatibility with human digestive systems.

5. Industrial Use: Adhesives and Packaging

Yellow dextrin is a leading component in envelope glue, cardboard packaging, and label adhesives. According to The Adhesive and Sealant Council, dextrin-based glues offer a strong bond while remaining biodegradable—an eco-friendly alternative to synthetic resins.
