- Fatty acid profile — oleic, linoleic, palmitic, stearic acid percentages
- Batch identification — production date, batch number, and expiration date
- Physical properties — color, odor, specific gravity, and refractive index
Typical Fatty Acid Profile
Each batch of our cold-pressed black seed oil is analyzed by GC-MS for fatty acid composition. Typical ranges across recent production batches:
Exact values vary naturally by harvest and batch; each batch's analysis report states its specific composition and is available on request.
