Water‑Soluble Resveratrol (5%) from China: What Buyers Really Need to Know

If you’re sourcing Grape Skin Extract Powder Resveratrol 5% Water Soluble Chinese Maufacturer, here’s the inside track from the factory floor to your formulation bench. Demand is shifting fast: beverage developers want transparent labels, gummies need flowable powders, and cosmetic labs ask for stable polyphenols without staining. Water-dispersible resveratrol at 5% hits that sweet spot—functional, cost-manageable, and frankly, practical for scale-up.

Product Snapshot and Specs

Assay (Resveratrol)	5.0% by HPLC (typical: 5.0–5.6%)
Water Solubility	Dispersible/clearable in water ≥95% at 25°C, pH 3–7 (real-world use may vary)
Appearance/Color	Fine purple-red to brownish powder, mild grape note
Carriers	Maltodextrin or β‑cyclodextrin (on request)
Moisture/Ash	≤5% / ≤5%
Compliance	Non‑GMO, BSE/TSE‑free, Non‑Irradiation, Allergen‑free
Shelf Life	24 months sealed, cool/dry, away from light

How It’s Made (Process Flow)

Materials: grape skins (EU/China origins audited) → ethanol/water extraction → clarification → membrane concentration → vacuum concentration → spray‑drying with carrier → standardization to 5% → blending → metal detection → packing. Testing checkpoints: HPLC assay (USP‑style), heavy metals by ICP‑MS (USP & GB), residual solvents (USP ), pesticides (GB 2763/EU 396), micro (TAMC/TYMC, pathogens), color/particle size. Service life is driven by moisture and light control—honestly, that’s where many projects slip.

Applications & Real‑World Feedback

• Functional beverages and stick packs (clear or lightly tinted, low sediment).
• Gummies/tablets with tight friability targets and low odor carryover.
• Cosmeceuticals/serums seeking polyphenol stories without gritty feel.
• Bakery and nutrition bars—color adds a “natural” cue.

What buyers report: “Good dispersion, minimal settling after 24h,” and “specs are consistent lot to lot.” I guess the micro results help—typical TAMC ≤1,000 cfu/g; pathogens absent.

Vendor Comparison (What to Watch)

Criteria	Finutra (Hebei)	Typical Trader (CN)	EU Brand
QA Docs	CoA + HPLC chromatogram + MSDS + Allergen	CoA only (≈)	Full pack + stability data
Lead Time	7–12 days ex‑works	10–20 days	3–5 weeks
Solubility Consistency	High (pilot samples match lots)	Variable	High
Price Index	≈1.0	≈0.9–1.1	≈1.6–1.9

Customization & Compliance

Options: 5–20% assay, 80–120 mesh, low‑dust granulation, β‑CD inclusion for clarity, flavored carriers. Certifications available: ISO 22000/FSSC 22000, HACCP, cGMP (dietary supplements), Halal/Kosher. Testing aligned to USP /, heavy metals by USP /, plus GB food safety standards.

Quick Case Study

A Southeast Asia RTD brand needed a tinted but clear drink with stable polyphenols. Using Grape Skin Extract Powder Resveratrol 5% Water Soluble Chinese Maufacturer, they ran a 10,000‑bottle pilot. Result: no haze at pH 3.5, color ΔE

Final thought: in fact, the safest bet is requesting a pre‑shipment sample from the same lot. For Grape Skin Extract Powder Resveratrol 5% Water Soluble Chinese Maufacturer, that tiny check often saves weeks later.
