  • Patent number: 9845442
    Abstract: A hydrodynamic cavitation method for degumming triglyceride oil is used to increase oil yield and reduce impurities. The residence time of the oil for degumming in the cavitation field is reduced to enhance removal of impurities such as phosphorus without prolonged exposure of the oil to cavitation conditions. The mass transfer of impurities from an oil phase to non-oil components or water is carried out in a non-cavitational, mass transfer reactor positioned downstream of a hydrodynamic cavitation device. A separation step can be used to remove the phosphatides and other impurities from the treated oil to form a purified oil product.

  • Patent number: 9816046
    Abstract: This invention discloses new krill oil compositions characterized by having high amounts of phospholipids, astaxanthin esters and/or omega-3 contents. The krill oils are obtained from krill meal using supercritical fluid extraction in a two stage process. Stage 1 removes the neutral lipid by extracting with neat supercritical CO2 or CO2 plus approximately 5% of a co-solvent. Stage 2 extracts the actual krill oils by using supercritical CO2 in combination with approximately 20% ethanol. The krill oil materials obtained are compared with commercially available krill oil and found to be more bioeffective in a number of areas such as anti-inflammation, anti-oxidant effects, improving insulin resistances and improving blood lipid profile.
