Inulin

Unlock the Power of Nature: Premium Inulin Extract from Zhonghong Biotech – Your Trusted Source for Bulk & Customized Solutions

1. What is Inulin?

Inulin is a naturally occurring fructan, a polymer of fructose molecules, classified as a soluble dietary fiber and prebiotic. Found abundantly in the roots and rhizomes of various plants, it serves as an energy storage carbohydrate. Structurally, it features β-(2→1) linkages between D-fructose units, typically terminating with a glucose molecule. This unique structure makes it resistant to digestion in the human upper gastrointestinal tract, allowing it to reach the colon intact where it selectively stimulates the growth and activity of beneficial gut bacteria (Bifidobacteria, Lactobacilli). Its versatile functional properties – including fat mimetic capabilities, moisture retention, texture enhancement, and sugar replacement – make it invaluable across food & beverage, nutraceutical, and cosmetic applications. As consumer demand for functional ingredients surges, sourcing high-purity inulin from a reliable supplier like Zhonghong Biotech is paramount.

2. Inulin: Source, Chemical Properties & Identification

• Primary Botanical Sources: Chicory root (Cichorium intybus) is the dominant commercial source, prized for its high inulin concentration (15-20% fresh weight). Other significant sources include Jerusalem artichoke (Helianthus tuberosus), agave (Agave spp.), dahlia tubers, garlic, onions, and asparagus.

• Chemical Properties:

  • Type: Linear fructan polysaccharide (oligofructose for shorter chains).

  • Solubility: Highly soluble in hot water, forming clear, viscous solutions. Low solubility in cold water.

  • Sweetness: Approximately 10% the sweetness of sucrose.

  • Caloric Value: ~1.5 kcal/g (due to partial fermentation in the colon).

  • Hygroscopicity: Exhibits significant moisture-binding capacity.

  • Gelling: Forms thermo-reversible gels when combined with water or milk, useful as a fat replacer.

• Key Identifiers:

  • CAS Number: 9005-80-5

  • Molecular Formula (MF): (C6H10O5)n (represents polymeric structure)

  • Molecular Weight (MW): Variable, typically ranging from ~3,500 to 5,500 Da for standard chicory inulin, up to >10,000 Da for native forms. Oligofructose ranges ~350-1,500 Da.

  • EINECS Number: 232-684-3

3. What is the Best Inulin? Key Considerations from Zhonghong Biotech
Choosing the optimal inulin extract requires evaluating several critical parameters to ensure efficacy, safety, and suitability for your application. Zhonghong Biotech sets the benchmark for quality:

• Composition & Purity: Premium inulin features a high degree of polymerization (DP avg >23 for long-chain) or specific DP profiles (e.g., oligofructose DP 2-8). Zhonghong utilizes advanced purification (e.g., membrane filtration, chromatography) to achieve >95% pure fructan content, minimizing monosaccharides, disaccharides, and ash. Our INLIGHT™ Inulin Series offers various DP profiles tailored to functional needs. Rigorous HPLC analysis guarantees composition.

• Efficacy & Health Benefits (Science-Backed & Compliant):

  • Prebiotic Powerhouse: Selectively feeds beneficial gut microbiota, enhancing microbial diversity and producing beneficial short-chain fatty acids (SCFAs) like butyrate. (EFSA Article 13.5 Claim: “Chicory inulin contributes to normal bowel function by increasing stool frequency” – requires min. 12g/day).

  • Blood Glucose Management: Reduces postprandial glycemic and insulinemic response by delaying carbohydrate digestion/absorption. (EFSA Article 14 Claim approved for “reduction of post-prandial glycaemic responses” – requires min. 10g/meal replacing sugars).

  • Enhanced Mineral Absorption: Improves calcium (and potentially magnesium) bioavailability and bone mineral density.

  • Weight Management Support: Promotes satiety, reduces energy intake.

  • Lipid Metabolism: May help maintain healthy blood lipid levels.

  • Immune Function Modulation: Linked to gut-mediated immune benefits.

• Optimal Daily Intake: General prebiotic effect: 5g-10g/day. For specific health claims (bowel function, glycemic response): 12g/day or 10g/meal respectively. Start with lower doses (2-3g/day) and gradually increase to minimize potential digestive discomfort. Individual tolerance varies.

• Origin & Processing: Zhonghong sources premium non-GMO chicory roots from sustainable European farms. Our proprietary low-temperature extraction and purification process preserves the native structure and bioactivity, avoiding harsh chemicals.

• Application Method: Easily incorporated into foods (baked goods, dairy, cereals, bars), beverages (smoothies, shakes, fiber drinks), supplements (powders, capsules, tablets), and cosmetics. Solubilize in warm liquids (>60°C) for best results. Dosage varies by application (1-15% typical in food).

• Target Demographic: Adults seeking digestive health, blood sugar management, weight support, enhanced mineral absorption, or general wellness. Suitable for diabetics (consult physician). Generally well-tolerated.

• Crucial Precautions & Potential Side Effects:

  • Gradual Introduction: Rapid increase can cause bloating, gas, cramps, or diarrhea due to gut fermentation. Increase dose slowly over weeks.

  • FODMAP Sensitivity: Inulin is a high-FODMAP fiber. Individuals with IBS or severe FODMAP intolerance should avoid or use extreme caution under medical/dietitian guidance.

  • Allergy: Rare, but possible allergy to chicory or related plants (ragweed, marigolds).

  • Medical Conditions: Consult a healthcare provider before significant intake if pregnant, breastfeeding, or with gastrointestinal disorders (e.g., SIBO).

10. Health Benefits: Mechanisms & Research Insights

• Prebiotic Mechanism: Inulin’s β(2-1) fructosyl bonds resist mammalian digestive enzymes. Upon reaching the colon, they are selectively fermented by saccharolytic bacteria. This fermentation produces SCFAs (acetate, propionate, butyrate), lowering colonic pH, inhibiting pathogens, and providing energy for colonocytes. Butyrate is crucial for gut barrier integrity and has anti-inflammatory effects. The bifidogenic effect modulates the immune system via gut-associated lymphoid tissue (GALT) interactions.

• Glycemic Control: Inulin increases digesta viscosity, delaying gastric emptying and macronutrient (especially carbohydrate) absorption in the small intestine. This blunts postprandial glucose spikes. SCFAs may also influence hepatic glucose production and insulin sensitivity via GLP-1 secretion.

• Mineral Bioavailability: Fermentation acidifies the colonic lumen, increasing solubility of minerals like calcium and magnesium, enhancing passive paracellular absorption. SCFAs may also stimulate transcellular transport pathways.

• Lipid Metabolism: SCFAs (especially propionate) may inhibit hepatic cholesterol synthesis. Inulin can also bind bile acids, promoting their fecal excretion and forcing the liver to use circulating cholesterol to synthesize new bile acids.
