Abstract: An simpler, cheaper method for enhancing the percentage of eicosapentaenoic acid (EPA) and/or docosahexaenoic acid (DHA) from source oils has been discovered. This method hydrolyzes the oil using the lipase enzyme but does not inactivate the lipase enzyme with either added chemicals or increased temperature. The method relies on centrifugation to separate the enzyme from the desired oil and separate the oil from aqueous impurities. The hydrolyzed oil is enhanced with EPA and DHA, and can be further purified by using activated surface adsorbents, e.g., activated alumina, to remove more free fatty acids and impurities.

Abstract: In one aspect, the invention relates to powdered, protein-rich comestibles and methods for producing same. Disclosed are powdered, protein-rich comestibles having a protein content of at least about 65%, a moisture content of less than about 5%, and a lipid content of less than about 10%, wherein the powder has an average particle size of less than about 65 ?m. In one aspect, comestibles can be derived from fish sources. Also disclosed are methods for producing powdered, protein-rich comestibles by isolating soluble proteins from a mixture of water and comminuted raw fish product and drying the isolate to a powder. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.
