1. What is Oat Beta-Glucan 70%?
Oat Beta-Glucan (CAS 9041-22-9) is a non-starch polysaccharide composed of linear chains of β-(1→3) and β-(1→4) linked D-glucopyranosyl units. At Exbiol®, we isolate the 70% fraction from premium Avena sativa bran. This high-density isolate is specifically engineered for pharmaceutical and clean-label functional foods, offering a bio-polymer matrix that maintains high metabolic affinity while providing industrial-scale solubility without the sediment common in lower grades.
2. Technical Specifications
Industrial grade soluble fiber isolate. Physical data points for formulation engineering:
- Molecular Weight Range: 90,000 – 110,000 Da (Controlled)
- Bulk Density: 0.35 – 0.55 g/ml
- Appearance: Fine white to light-yellow powder
- pH (1% Sol.): 6.0 – 8.0
3. Source & Origin
Exbiol® sources non-GMO oats exclusively from GAP-compliant high-latitude regions. We utilize an Aqueous Green Extraction process. By avoiding chemical solvents and using ultra-filtration membrane separation, we preserve the triple-helix structure of the glucan chains, ensuring 100% biological property support for cholesterol-binding receptors.
4. Mechanism of Action
The efficacy of Oat Beta-Glucan is driven by its Viscosity-Mediated Entrapment. In the digestive tract, it forms a high-molecular-weight gel that traps bile acids and dietary cholesterol, increasing their excretion. At a cellular level, it interacts with the Dectin-1 receptors on immune cells, providing a functional property of immune-signaling modulation.
Rheology Engineering (Mw Control)
Industrial challenge: Excessive gumming in beverages. Exbiol® solve this via Precision Ultra-filtration. By maintaining Mw at ~95kDa, we ensure 100% pourability in 5% solutions, whereas standard glucans gel at 1.5% inclusion.
Thermal Stress Stability
Our 70% fraction is engineered for Retort and UHT conditions. Validated testing at 121°C for 15 minutes shows <2.0% degradation of active β-(1,3/1,4) chains, ensuring label claim compliance after sterilization.
Hygroscopicity Management
High-purity glucans are prone to caking. We utilize Fluid-Bed Anti-Aggregation technology to ensure an 80-mesh free-flowing powder, perfect for high-speed automated capsule and sachet filling.
5. Application Benefits
- Cardiovascular Support: Functional property for supporting healthy LDL levels (EFSA Compliant).
- Glycemic Homeostasis: May support a functional reduction in postprandial glucose response.
- Dermal Soothing: Formulation advantage: Superior water-holding capacity for medical-grade barrier repair.
6. Usage & Formulation Guide
- Dissolution: Add to aqueous phase with high-shear mixing for 5-10 mins.
- pH Tolerance: Structural integrity maintained from pH 3.0 to 8.5.
- Synergy: Highly compatible with whey/pea proteins; prevents protein-sedimentation in neutral pH drinks.
7. Industrial Evolution
The industry has moved from crude oat flour (5% glucan) to second-gen 20-30% extracts. Exbiol’s Third-Generation 70% Isolate represents the transition to “Concentrated Active Platform” technology, allowing for therapeutic doses in small serving sizes without the “sludge” mouthfeel of legacy ingredients.

17. Technical FAQ for Bulk Buyers
Q: How do you verify the 70% assay specifically for Beta-Glucans?
We utilize AOAC Method 995.16. This involves enzymatic hydrolysis followed by HPLC-RI detection, ensuring we distinguish active glucans from non-functional starch and dextrins.
Q: What is the “Viscosity-to-Concentration” ratio in liquid formulations?
Our Mw control (~95kDa) ensures that a 5% solution remains pourable (<500 cP). This allows for heart-health claims (3g/day) in small, sensory-friendly serving sizes.
