Overview
Chicory polysaccharide, primarily composed of inulin-type fructans, is extracted from the roots of the chicory plant (Cichorium intybus). It is a natural prebiotic that promotes gut health by stimulating the growth of beneficial bacteria like Bifidobacteria. Due to its low-calorie and high-fiber properties, it is widely used in functional foods and dietary supplements. In the industrial sector, chicory polysaccharide is valued for its versatility. It acts as a fat replacer, stabilizer, and sugar substitute in processed foods. Its neutral taste and solubility make it suitable for beverages, dairy products, and baked goods.
Physical and Chemical Properties
Chicory polysaccharide is a white to off-white powder with a mildly sweet taste. Its molecular structure consists of β-(2→1) linked fructosyl units, often terminating with a glucose molecule. This configuration makes it resistant to digestion in the upper gastrointestinal tract, allowing it to reach the colon intact. The polysaccharide is hygroscopic and absorbs moisture from the environment, requiring airtight storage. It dissolves readily in hot water but forms a gel-like substance in cold water. Its thermal stability is moderate, decomposing at temperatures above 150°C without melting.
Main Applications
In the food industry, chicory polysaccharide is used as a dietary fiber additive in products like yogurt, cereal bars, and low-sugar snacks. Its prebiotic effects support digestive health, making it a popular ingredient in functional foods. It also serves as a fat mimetic in reduced-calorie products. The pharmaceutical industry utilizes chicory polysaccharide in probiotic formulations and as an excipient in tablet coatings. In animal feed, it enhances gut microbiota balance in livestock and pets. Recent research explores its potential in biodegradable packaging due to its film-forming properties.
Safety and Storage
Chicory polysaccharide is classified as GRAS by the FDA and is safe for most consumers. However, excessive intake (over 20g/day) may cause gastrointestinal discomfort, such as bloating or flatulence, in sensitive individuals. Allergic reactions are rare but possible. Proper storage is critical to maintain quality. The powder should be kept in sealed containers at room temperature (below 25°C) with relative humidity under 65%. Prolonged exposure to moisture can lead to clumping or microbial growth. Shelf life typically ranges from 2 to 3 years when stored correctly.
B2B Procurement Guide
When sourcing chicory polysaccharide, prioritize suppliers with ISO or GMP certifications to ensure quality consistency. Key specifications to verify include purity (≥90%), degree of polymerization (DP), and microbiological limits. Organic or non-GMO certifications may be required for specific markets. Bulk pricing varies based on order volume and purity. For large-scale procurement (1+ metric tons), negotiate contracts with manufacturers to secure competitive rates. Sample testing is recommended to confirm solubility, taste, and compatibility with your application. Lead times typically range from 2 to 6 weeks, depending on supplier location.
