Inulin

Description

Inulin is a naturally occurring polysaccharide produced by many types of plants. It is classified as a soluble dietary fiber and is commonly extracted from chicory root. Inulin is widely used in the food and health industries for its functional properties as a prebiotic fiber, fat replacer, and texture modifier.

Chemical Characteristics

• Appearance: White to off-white fine powder

• Taste: Mildly sweet (about 10% the sweetness of sucrose)

• Solubility: Soluble in hot water

• Stability: Stable under acidic and neutral pH; breaks down under prolonged high heat

• Type: Fructan polysaccharide composed primarily of fructose units linked by β-(2→1) glycosidic bonds, typically ending with a glucose unit

• Prebiotic Effect: Stimulates growth of beneficial gut bacteria, especially Bifidobacteria

Applications

1. Food and Beverage Industry

   • Used as a dietary fiber to improve digestive health

   • Fat substitute in dairy products, baked goods, and spreads

   • Sugar replacer in low-calorie and sugar-free products

   
   

2. Nutraceuticals and Dietary Supplements

   • Prebiotic fiber supporting gut health

   • Enhances calcium and magnesium absorption

   
   

3. Pharmaceutical Industry

   • Used as an excipient in tablet formulations for improved texture and stability

   
   

4. Animal Nutrition

   • Added to animal feed to promote intestinal health and nutrient absorption
