1. What is Blueberry Fruit Powder?
Blueberry Fruit Powder is a concentrated nutritional isolate derived from the whole fruit of Vaccinium angustifolium or Vaccinium corymbosum. Unlike simple dried fruit, Exbiol® utilize **Freeze-Drying (FD) technology** to preserve the heat-sensitive **anthocyanin glycosides** and enzymes. This results in a free-flowing, nutrient-dense powder that provides a functional property of high ORAC (Oxygen Radical Absorbance Capacity) for clean-label food and supplement matrices.
2. Technical Specifications
| Parameter | Industrial Specification |
|---|---|
| Anthocyanin (HPLC) | 1.0% — 5.0% (Standardized) |
| Molecular Mass (Cyanidin-3-glucoside) | 449.38 g/mol |
| Moisture Content | ≤ 5.0% (Freeze-Dried) |
| Mesh Size | 95% Through 80 Mesh |
3. Source & Origin
Sourced from GAP-compliant farms in the Qinling Mountains and North American wild zones. We prioritize the **Lowbush (Wild) varieties** due to their naturally higher skin-to-pulp ratio, which yields a deeper purple pigment and superior antioxidant density. DNA Barcoding ensures zero adulteration with grape or mulberry derivatives.
4. Mechanism of Action
The biological activity is centered on the Flavylium Cation structure of anthocyanins. These molecules donate hydrogen atoms to neutralize free radicals and modulate the **Nrf2-mediated antioxidant response**. Industrially, the powder acts as a natural humectant and pH-sensitive pigment, supporting the functional property of vision and cardiovascular health markers.
The Anthocyanin Degradation Challenge
Problem: Anthocyanins are highly sensitive to pH shifts and thermal oxidation during spray-drying, leading to “Browning” (loss of purple color).
Exbiol Solution: We utilize Cryogenic Freeze-Drying (-40°C). By skipping the heat-intensive spray-drying phase, we ensure 95% retention of the natural deep-purple hue and active antioxidant bonds, significantly extending the shelf life of functional beverages.
6. Usage & Formulation Guide
Solubility: Cold Water Dispersible (CWD). Our powder provides instant dispersion without clumping. Processing: Avoid temperatures above 60°C in open vessels. pH Range: Most stable and vibrant at pH 2.5 — 4.5. For neutral pH systems (dairy), utilize our stabilized encapsulate grade.
7. Industrial Evolution
From simple sun-dried berry mashes to modern Standardized Fruit Isolates. Exbiol’s 4th-gen extraction technology focuses on “Full-Spectrum Nutritional Fingerprinting,” moving beyond simple flavor to delivering pharmaceutical-grade phytochemicals in a whole-food format.

17. Technical FAQ (Closed-Loop Decision Center)
Q: How do you verify the 1%-5% Anthocyanin assay for bulk orders? (Ref: Section 04)
We utilize HPLC-DAD (AOAC 2005.02) specifically mapping the five primary anthocyanoside isomers. This prevents false positives from synthetic dyes or mulberry extracts common in UV-only testing.
Q: Can you provide raw LC-MS data for our quality audit? (Ref: Section 05)
Yes. For contract manufacturers, we provide full LC-MS/MS fingerprinting and HPTLC Botanical Identification to confirm the wild lowbush variety species authenticity.
Q: How is the ‘Sublimation Stability’ managed during logistics? (Ref: Section 11)
Our Freeze-Dried crystals are Nitrogen-Locked at the drying stage. We use 1.0mm PE vacuum liners that prevent oxygen permeability, maintaining the vibrant purple hue even during 45-day sea freight.
Q: Do you support custom mesh sizes for sachet filling? (Ref: Section 14)
Yes. Our standard is 80 mesh, but for instant RTD sachet production, we offer 120-mesh micronization to ensure uniform dispersion and zero mouth-grittiness.
Q: Is your technical documentation dossier ready for FDA audit? (Ref: Section 12)
Absolutely. Every industrial batch is released with a Full Regulatory Package including MSDS, TDS, Flow Chart, and No-GMO declarations compliant with US DSHEA guidelines.
