    Abstract: Methods and compositions are provided for producing purified oil from an organism, whether these organisms are wild type, selectively bred or genetically modified, and are suitable for the large scale production of an oil product. The organism may be an animal, a plant or a microorganism such as yeast, bacteria or algae. The organism is processed to create a biomass which can be extracted to remove the lipids contained within the biomass. The extraction produces a crude extract rich in lipids and containing residual contaminants. These contaminants are removed by contacting the crude extract with a composition that comprises a nanomaterial. Subsequently an oil product is recovered which is substantially free from residual contaminants, such as pigments.

The pH of the ground animal tissue is reduced to a range of from approximately 3.5 to approximately 4.5 and the ground tissue is allowed to decompose through the action of digestive enzymes released from the visceral tissue of the animal tissue by the maceration step. The decomposed tissue is separated into a lipid portion, a proteinaceous portion and a bone fragment or hard tissue portion. At least a part of the lipid portion may then be extracted from the decomposed tissue for further processing or disposal of contaminants and pollutants contained therein.

    Abstract: A processing method used for separating bone and oil from marine byproducts in the preparation of an endproduct. The byproducts are ground and then warmed to a relatively low temperature of approximately 70 deg.C. or less. The warmed material is passed to a refiner to separate the bone from the meat portions. The meat portion is transferred to a digestion tank where the endogenous enzymes perform a first stage digestion. Exogenous enzymes may be added and further digestion may take place for increased liquefaction of the meat portion. The exogenous enzymes can survive temperatures higher than the 60-65 deg.C. range so the liquified material can be heated during the further digestion to increase hydrolysis and pasteurize the product. Oil may be removed from the product by centrifuge following completion of either digesting step. Evaporation of the product may be used to increase the percentage of solid material. Alternatively, the oil may be removed after digestion without mechanically deboning the byproducts.

    Abstract: A fat reforming method using an enzyme which has been activated by adding the enzyme to a system containing water and fat phases, activating the enzyme by a function of a boundary surface/layer between the water and fat phases, and removing the water and fat phases through freeze drying. Tetradecane may be used as the fat phase. Just after adding tetradecane into a water phase in which lipase is dissolved, though existing in water phase as shown in FIG. 4(a), the lipase moves towards the boundary surface since it has a tendency to gather around the boundary surface between the water and fat phases. The lipase moved to the boundary surface has hydrophobic portion at the side of the fat phase and a hydrophilic portion of the lipase at the side of the water phase, as shown in FIG. 4(b), and at the same time the lid covering the activating portion is opened by the function of the boundary surface.

The process consists of supplying a homogenisation and/or processing vessel (1) with effluent to be pre-treated, as it is produced, activating a recirculation circuit (2) between the vessel and a biological reactor (3) to obtain a fat dilution rate situated between 0.400 h−1 and 1.500 h−1 for an initial fat concentration of 1 g/l, degrading the fats in the biological reactor (3) using the bacterial composition and discharging the pre-treated effluent to a final treatment unit such as a purification plant.

  • Patent number: 6103516
    Abstract: A method for extracting vegetable oils from oleaginous plants in which the solid parts of the plants, which contain oils embedded in macromolecular polysaccharide substances typical of the integument of the plants, are subjected to an enzyme attack by means of at least one enzyme which lyses at least that polysaccharide. Then the oil contained in the solid parts is recovered by means of conventional mechanical recovery stages without using a solvent-based extraction stage.

  • Patent number: 6001640
    Abstract: A degumming step in the production of edible oils is disclosed. Vegetable oils from which hydratable phosphatides have preferably been eliminated by a previous aqueous degumming process, are freed from non-hydratable phosphatides by an enzymatic treatment, so that they may be physically refined. The main characteristic of the invention is the use of phospholipase from an Aspergillus strain. The process is gentle, economical and environment-friendly.

  • Patent number: 5929212
    Abstract: The invention provides recombinant antibody molecules comprising antigen binding regions derived from the heavy and/or light chain variable regions of a donor anti-CD3 antibody, e.g. OKT3, and which have anti-CD3 binding specificity, preferably of affinity similar to that of OKT3. The recombinant antibody is preferably a humanized antibody and may be a chimeric or CDR-grafted antibody. A method is disclosed for preparing CDR-grafted humanized antibodies in which, in addition to the CDR's, non-human antibody residues are preferably used at positions 23, 24, 49, 71, 73 and 78 of the heavy chain variable region and at positions 46, 48, 58, and 71 of the light chain variable region. The recombinant, especially the humanized, anti-CD3 antibodies may used for in vivo therapy or diagnosis.

  • Patent number: 5532163
    Abstract: This invention provides processes for the refining of oil and fat by which phospholipids in the oil and fat to be treated can be decomposed and removed efficiently. Particularly, it provides a process for the refining of oil and fat which comprises reacting, in an emulsion, the oil and fat with an enzyme having an activity to decompose glycerol-fatty acid ester bonds in glycerophospholipids (e.g., pancreas-derived phospholipase A.sub.2); and another process in which the enzyme-treated oil and fat is washed with water or an acidic aqueous solution. Preferably, the acidic aqueous solution to be used in the washing step is a solution of at least one acid selected from the group consisting of citric acid, acetic acid, phosphoric acid and salts thereof. Also, it is preferred that the emulsified condition is formed using 30 weight parts or more of water per 100 weight parts of the oil and fat.
