Abstract
Marine animal oil free of undesirable odor or taste is produced by treating a freshly killed marine animal with a peroxidase-inhibiting antioxidant, disaggregating the marine animal, separating the oil phase, mixing with a dilute aqueous acidic solution, removing the oil phase and adding antioxidant. Marine animal oil which has already turned rancid may be restored to a non-rancid state by mixing with a reducing antioxidant such as a thiodipropionate, separating out the fatty acids which have reacted with the antioxidant, preferably by column chromatography, and adding another antioxidant to prevent further peroxidation.
