A lot of brands in this industry like to treat a lab report as a one-and-done marketing asset. They get a good test result back in the day, put the PDF on their homepage, and use it forever.
That isn't how agriculture works.
Black seed is a natural crop. Every single season brings different amounts of rainfall, sunny days, and soil conditions as a result. Because the raw seed changes from harvest to harvest, the chemical profile moves around too.
We operate on one non-negotiable rule: New harvest, new lab test
We have tested with Eurofins and used two methods:
-
HPLC: 3.02% TQ
-
NMR: 2.99% TQ (29,907 mg/kg)
HPLC is the liquid chromatography gold standard that isolates and measures Thymoquinone via UV light absorption at room temperature
NMR is Eurofins' proprietary magnetic spectroscopy method that they have adapted for use on oils that verifies the molecule's exact atomic hydrogen signature.
There are many other methods used by the industry. For example our supplier told us that one of their customers came back with extremely good TQ results of 4%, from the oil of the same seeds that we have. However, the method was used was GC-MS. GC-MS makes no sense for us because while we fight for every single degree Celsius during cold pressing, GC-MS blasts the oil at 250°C in the lab, completely distorting the true TQ number.
