Quercetin Bulk Powder

Quercetin Bulk Powder – Premium Plant Extract for Nutraceutical Manufacturing

Xi'an Linnas Biotech Co., Ltd. supplies pharmaceutical-grade Quercetin Bulk Powder produced in accordance with ISO 9001, HACCP, HALAL, and KOSHER certifications, with 95% purity confirmed by HPLC. Advanced alkaline extraction and acid precipitation techniques are used to obtain our product from Sophora japonica flower buds. This light yellow powder exhibits remarkable stability for solid-dose applications, with a thermal breakdown point of 314°C. To guaranty that the heavy metal concentration stays below 10 ppm and satisfies USP/EP pharmacopeial standards, every batch is subjected to stringent quality control. We deliver within three days of payment confirmation and offer them in 20–25 kg drums or 1–10 kg foil packs.

Product Specifications

Superior Quality from Natural Sources

Instead than using artificial substitutes, our Quercetin Bulk Powder is made only from Sophora japonica flower buds. Compared to onion or apple sources, this botanical source guaranties greater purity and extraction efficiency.

The genuine quercetin content is indicated by the yellow needle-shaped crystalline structure. In order to avoid contamination with less expensive flavonoid alternatives, we confirm identity using HNMR and IR spectrum analysis against USP Reference Standards.

There are sophisticated micronized versions with D90 < 10 microns. By expanding the surface area for better absorption in dietary supplement formulations, they improve bioavailability.

Applications Across Industries

This chemical is used by food manufacturers to enhance pigment light resistance and stop flavor deterioration. It is perfect for baking and heat-processed functional meals due to its strong thermal stability.

Brands of dietary supplements use it in powder blends, pills, and capsules. During manufacture, precise calculations of capsule fill weight are made possible by the powder's constant bulk density.

Its strong antioxidant qualities are valued by cosmetic formulators for anti-aging skincare products. It works well in both oil-based and water-based formulations when paired with the right solubilizers.

Manufacturing Excellence & Quality Assurance

Strict environmental controls are maintained during the extraction and drying operations in our automated production plant. By doing this, oxidation that results in color changes from vivid yellow to undesirable brown tones is avoided.

Every production batch is thoroughly tested for microbiological contaminants, pesticide residues, heavy metals, and purity. We offer complete analytical documentation, such as third-party test reports and Certificates of Analysis.

To prevent exposure to air and UV light, the powder is packaged right away in light-resistant aluminum bags. Assay levels are maintained during the normal two to three-year shelf life with proper packing.

Enhanced Bioavailability Solutions

Absorption rates are impacted by the limited water solubility of standard crystalline quercetin. We provide technical assistance for formulation techniques that get around this obstacle.

For improved dissolving, the surface area of micronized powder versions is greatly increased. Alternatively, phytosome delivery systems can be created by combining with bio-enhancers such as piperine or phospholipid complexes.

Our technical staff works with clients to create formulations that meet certain bioavailability goals. This advice service assists in maximizing the effectiveness of dose forms.

OEM & ODM Custom Manufacturing

From ingredient modification to final product packaging, Linnas offers full turnkey solutions. Our skilled formulators create exclusive mixes that satisfy your brand's requirements.

From small batch experiments to large-scale commercial production, we can handle orders of all sizes. Product launches are delivered on time thanks to specialized production lines and flexible manufacturing schedules.

Custom packaging design, assistance with regulatory documents, and quality testing procedures are examples of private label services. This all-encompassing strategy simplifies your supply chain administration.

Packaging Options

We provide fiber drums with inner polyethylene liners (20–25 kilogram) for commercial manufacturing or food-grade aluminized foil bags (1–10 kg) for laboratory volumes. For large-volume orders, custom packaging options are offered.

Tamper-evident seals and desiccant packets are included with every shipment. For regulatory compliance, we offer comprehensive paperwork such as COA, MSDS, and allergen declarations.

Frequently Asked Questions

Q: What distinguishes anhydrous from dihydrate forms?

A: Dihydrate provides better stability for supplement uses and has two crystal water molecules. Higher concentration (>98% potency) is possible with anhydrous, although strict moisture management during storage is necessary.

Q: How can the color be maintained consistently throughout batches?

A: Batches exhibiting oxidation-related browning are rejected by our quality control, even though natural fluctuations from bright yellow to greenish-yellow occur due to harvest timing. Color constancy is maintained by quick packaging and regulated drying temperatures.

Q: Is there no solvent used in the extraction process?

A: We employ aqueous precipitation after ethanol extraction, which qualifies it for clean label claims. The finished product satisfies US and EU clean label certification requirements and is non-GMO and allergy-free.

Q: What tests distinguish genuine quercetin from adulterants?

A: Since numerous flavonoids exhibit similar absorption, standard UV testing is inadequate. To ensure genuine powder composition, we match HNMR or IR spectra against reference standards.

Q: What storage circumstances preserve potency?

A: Keep at a controlled room temperature, away from moisture and oxygen, in sealed, light-resistant containers. Throughout the shelf life, proper storage maintains the 95% purity criterion.
