Our black cumin seed extract adopts ethanol‑water dual extraction, purification and spray‑drying production workflow. Multiple separation steps remove seed oil residues, coarse fiber and unrelated impurities to retain stable thymoquinone. Many bulk black cumin seed extracts on the market face unstable active content caused by raw‑material differences and simplified processing, which brings risks to finished‑product consistency. Our extract powder delivers even colour, fine particle size and good flowability, performing steadily across batches for large‑scale formulation. No artificial colours, synthetic preservatives or redundant fillers are added throughout manufacturing.

Our Supplier Advantages

We maintain stable black cumin seed sourcing and complete extraction, purification and drying production lines. Strict in‑house quality control guarantees reliable quality for bulk export orders.

• Rigorous raw‑material screening: Qualified nigella sativa seeds are selected; regular testing covers heavy metals, pesticide residues and microbial limits.

• Optimized purification process: Effectively removes excess seed grease and miscellaneous impurities to secure stable thymoquinone content.

• Batch‑by‑batch full inspection: Each shipment completes HPLC thymoquinone test, moisture, heavy‑metal and microbial detection before release.

• Custom service available: Support thymoquinone content adjustment, particle‑size modification and private‑label packaging solutions.

• Flexible ordering: 1 kg sample orders are acceptable. Complete export documents including COA, MSDS and test reports can be provided for customs clearance.

Packaging & Storage Guidelines

• Standard Export Packaging: 1 kg aluminum foil bag; 25 kg food‑grade fiber drum with inner plastic lining bag

• Storage Conditions: Store in cool, dry, dark and ventilated warehouse. Keep away from high temperature, moisture and direct sunlight.

FAQ

Q1: What is the key testing component for black cumin seed extract?
A1: Thymoquinone is the core active marker for commercial black cumin seed extract, widely recognized by global supplement manufacturers. We can supply goods matching your target thymoquinone specification.

Q2: What is the difference between raw black cumin seed powder and concentrated black cumin seed extract?
A2: Plain seed powder contains large amounts of grease and fiber with low thymoquinone content. Concentrated extract enriches thymoquinone with stable test values and works better for standardized finished‑product manufacturing.

Q3: What about MOQ and lead‑time?
A3: MOQ starts at 1 kg for sample evaluation. Bulk goods are normally in stock. Custom‑spec orders need separate lead‑time confirmation.
