  • Patent number: 4619789
    Abstract: A rendering system and method is provided for the rendering of organic materials into its major components comprising water, fat and solid proteins. The process involves mixing additional fat with the raw material to form a pumpable slurry including fat and water emulsions. The slurry is treated to break the emulsions and insolubilize the protein solids wherein the fat becomes a continuous phase fat in the slurry and the water becomes a continuous phase water. The treating comprises adding fat to the raw material having a temperature within the range of 140.degree. F. to 270.degree. F. in an amount such that the ratio of added fat to the dry defatted solids of the slurry is in the range of 4 to 1 to 6 to 1, respectively. The treating further includes partially drying the slurry such that at least 15 percent by weight of water as measured as a percentage of total water and defatted solids remains with the solids which discharge from the partial drying step as part of the partially dried slurry.

  • Patent number: 4615839
    Abstract: A fatty acid composition is produced by subjecting a lipid composition extracted from marine chlorella to solvent fractionation to remove neutral fats, chlorophyll, sterols and majority of phospholipids, thereby providing a polar lipid composition. The polar lipid composition is then subjected to hydrolysis to liberate fatty acids. Finally, the fatty acids are recovered, thereby providing a fatty acid composition with not less than 60% by weight of eicosapentaenoic acid.
