Pumpkin seed oil

Pumpkin seed oil suppliers and sourcing guide

Pumpkin seed oil is pressed from the seeds of Cucurbita pepo, often from hull-less varieties. The traditional Styrian style roasts the ground seeds before pressing, giving a dark green, nutty oil; cold-pressed oil from raw seeds is lighter in color and flavor. Brands buy it for softgels, bottled culinary oils and cosmetics.

What to check on the COA

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

Fatty acid profile
Linoleic and oleic acids by GC as methyl esters to confirm identity.
Free fatty acids and peroxide value
Free fatty acids (as oleic acid) by titration (AOCS Ca 5a-40) and peroxide value (AOCS Cd 8b-90); both rise as the oil ages or is handled poorly.
PAHs
Polycyclic aromatic hydrocarbons such as benzo[a]pyrene by GC-MS, relevant for roasted oil.
Pesticide residues
Multi-residue screen by GC-MS/MS and LC-MS/MS.
Heavy metals
Lead, cadmium, arsenic and mercury by ICP-MS, reported against the supplier specification.
