BIOEFFECTIVE KRILL OIL COMPOSITIONS

摘要

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.

主权项

1. A method of production of krill oil comprising:
a) providing krill; b) treating said krill to denature lipases and phospholipases in said krill to provide a denatured krill product; c) storing said denatured krill product for a period of from 1 to 24 months; d) extracting oil from said denatured krill product with a polar solvent to provide a krill oil with from about 3% to about 15% ether phospholipids w/w of said krill oil astaxanthin esters in amount of greater than about 100 mg/kg of said krill oil.
