BioNatal is the only company in the world to prove the cold pressing method through analysis. Most consumers of black seed oil look at the label contents of the oil bottles, but no one has ever seen official proof. Most of the world's black cumin seed oil suppliers are based in the Middle East and Africa, and these regions use old industrial equipment made for soft sunflower seeds and olive pulp, and are not equipped for the Nigella Sativa seeds. As a result, almost all of the black seed oil in the world market gets burned during pressing, and resellers always say that it is impossible to prove that the extraction was cold officially, which is not valid.
It's effortless to prove cold press, but most black seed oil manufacturers are not interested in these tests. BioNatal has the results of oil analyzes produced on our equipment, where the Benzo(a)pyrene component does not exceed 0.95 μg / kg while the global cold-pressed standard does not exceed 2.0 μg / kg
