Ahiflower oil

Ahiflower oil suppliers and sourcing guide

Ahiflower is a trade name for the oil pressed from the seeds of Buglossoides arvensis (corn gromwell), a plant in the borage family grown under contract, mainly in the United Kingdom. The seed is cold-pressed and the oil is refined. It contains stearidonic acid (SDA) together with alpha-linolenic and gamma-linolenic acids, which sets it apart from flax and borage oils. Brands buy it as bulk oil for softgels and liquids, or as a powder.

Microencapsulated oil on a carrier for powders, tablets and food applications, at a lower oil content per gram.

What to check on the COA

Compare each result with your own specification when the lot arrives.

Fatty acid profile: SDA, ALA, GLA and linoleic acid by GC of methyl esters, the main identity and potency check.
Peroxide, anisidine and TOTOX: Peroxide and p-anisidine values and the calculated TOTOX value, since the oil is highly unsaturated.
Acid value: Acid value by titration.
Heavy metals: Lead, cadmium, mercury and arsenic by ICP-MS.
Pyrrolizidine alkaloids: Some buyers ask for pyrrolizidine alkaloid testing by LC-MS/MS because the plant belongs to the borage family.
