How is shark squalene harvested?
Traditionally, squalene is harvested from deep-sea shark livers, which has the potential to devastate shark populations and have long-lasting ecological consequences. Amyris’ sugarcane-derived squalene can help offset this issue by providing a pharmaceutical grade alternative to shark-derived squalene.
Does olive oil contain squalene?
Squalene is found in olive oil at a concentration ranging from 0.7 to 12 g per kilogram of oil. The squalene content depends on the olive cultivar and oil-extraction technology, and it is dramatically reduced during the process of refining.
