This section covers key questions related to quality, safety, and international shipping for wholesale buyers.
In the international spice trade, the term “Black Cumin” is often used for two different plants. True Black Seed (Nigella sativa), which DITCO specializes in, belongs to the Ranunculaceae family and is characterized by its triangular, pitch-black seeds and high Thymoquinone content. Bunium bulbocastanum (Kala Jeera) belongs to the Apiaceae family and is a long, thin seed primarily used as a spice. For pharmaceutical and therapeutic oil applications, Nigella sativa is the industry standard due to its unique chemical profile.
Thymoquinone (TQ) is the primary bioactive compound responsible for the medicinal properties of Black Seed. Turkish origin Nigella sativa is globally prized for its high potency. In our technical specifications, the fixed oil extracted from these seeds typically contains a TQ concentration ranging from 0.5% to 1.5%, depending on the harvest. For B2B clients in the supplement and pharmaceutical sectors, we provide a Certificate of Analysis (COA) to verify TQ levels and antioxidant activity.
Purity is a critical quality marker for preventing cross-contamination in food and oil production. DITCO offers Black Seeds with purity levels of 99%, 99.5%, and 99.9% (Sortex Quality). Our seeds undergo an intensive cleaning process involving vibration sifting, de-stoning, and advanced optical color sorting (Sortex). This ensures the total removal of flat seeds, stalks, stones, and foreign botanical matter, resulting in a uniform, high-quality raw material.
For industrial oil pressers, the oil yield is the most important ROI factor. Our Black Seeds typically yield a fixed oil content of 30% to 38%. The oil is rich in essential fatty acids, primarily Linoleic Acid (Omega-6) at 50-60% and Oleic Acid at 20-24%. Because we maintain low moisture levels (below 9%) and utilize cool-temperature cleaning, the seeds remain stable for high-yield cold-pressing, preserving the delicate volatile components and vitamins.
Black Seeds are subject to strict monitoring for Maximum Residue Limits (MRLs) of pesticides and heavy metals. DITCO complies with EU Regulation (EC) No 396/2005 and FDA standards. Additionally, because these seeds are often grown in diverse soil conditions, we perform rigorous testing for PAHs (Polycyclic Aromatic Hydrocarbons) and microbiological parameters. We offer Steam Sterilization (SS) as an optional treatment to ensure the seeds are 100% free from Salmonella and E. coli for ready-to-eat applications.
To protect the high oil content from oxidation and rancidity, DITCO packs bulk Black Seeds in 25 kg or 50 kg multi-wall kraft paper bags with food-grade PE liners or double-layered polypropylene bags. To maintain a shelf life of 24 months, it is technically recommended to store the seeds in a cool ($<20$°C), dry, and dark environment. Maintaining a moisture level of max 9% is essential to prevent lipase activity, which can lead to increased acidity in the extracted oil.
