PRODUCTION AND USE OF A POLAR LIPID-RICH FRACTION
CONTAINING OMEGA-3 AND/OR OMEGA-6 HIGHLY UNSATURATED
FATTY ACIDS FROM MICROBES, GENETICALLY MODIFEED
PLANT SEEDS AND MARINE ORGANISMS
FIELD OF THE INVENTION
The present invention relates to the fields of production and use, and in particular, the extraction, separation, synthesis and recovery of polar lipid-rich fractions containing eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), docosapentaenoic acid (DPA(n-3) or DPA(n-6)), arachidonic acid (ARA), and eicosatetraenoic acid (C20:4n-3) from microorganisms, genetically modified seeds and marine organisms (including fish and squid) and their use in human food applications, animal feed, pharmaceutical applications and cosmetic applications.
BACKGROUND OF THE INVENTION
Highly unsaturated fatty acids of the omega-6 and omega-3 series represent a special class of bioactive lipids in that they are important structurally in membranes in the body, but also participate directly and indirectly in communication between cells through the eicosanoid pathways and by their influence of these fatty acids on gene expression. Six of these fatty acids, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), docosapentaenoic acid (DPA(n-3) or DPA(n-6)), arachidonic acid (ARA), and eicosatetraenoic acid (C20:4n-3) have been shown to be effective in preventing/treating cardiovascular disease, inflammatory disease, immune function imbalances, fertility and some of these fatty acids (ARA, DHA DPA(n-6) are important structurally in the brain and nervous system. Recent evidence indicates that some highly unsaturated fatty acids may be more bioavailable when supplied in a phospholipid form than in a triglyceride form. EPA, DHA, and ARA have historically been supplied to the nutritional supplement markets in the form of oil extracted from algae or fish. However recent evidence indicates that some polyunsaturated fatty acids may be more bioavailable in a phospholipid form rather than in a triglyceride form. This may be because of the bipolar nature of phospholipids, making them readily solubilizable in the gut and available for digestion and uptake. This same bipolar property of phospholipids additionally would make these fatty acids more functional in topical applications such as creams and lotions or more soluble in aqueous-based applications such as beverages because of there ability
to participate in emulsification processes. We propose that there may be important advantages in supplying these omega-3 and omega-6 HUFAs in the form of phospholipids and improved processes for recovering polar lipids enriched in these fatty acids are also needed. Examples of polar lipids include phospholipids (e.g. phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, phosphatidylserine, phosphatidyl- glycerol, diphosphatidylglycerols), cephalins, sphingolipids (sphingomyelins and glycosphingolipids), and glycoglycerolipids. Phospholipids are composed of the following major structural units: fatty acids, glycerol, phosphoric acid, and amino alcohols. They are generally considered to be structural lipids, playing important roles in the structure of the membranes of plants, microbes and animals. Because of their chemical structure, polar lipids exhibit a bipolar nature, exhibiting solubility or partial solubility in both polar and non-polar solvents. The term polar lipid within the present description is not limited to natural polar lipids but also includes chemically modified polar lipids. Although the term oil has various meanings, as used herein, it will refer to the triacylglycerol fraction.
One of the important characteristics of polar lipids, and especially phospholipids, is that they commonly contain polyunsaturated fatty acids (PUFAs: fatty acids with 2 or more unsaturated bonds). In many plant, microbial and animal systems, they are especially enriched in the highly unsaturated fatty acids (HUFAs: fatty acids with 4 or more unsaturated bonds) of the omega-3 and omega-6 series. Although these highly unsaturated fatty acids are considered unstable in triacylglycerol form, they exhibit enhanced stability when incorporated in phospholipids.
The primary sources of commercial PUFA-rich phospholipids are soybeans and canola seeds. These biomaterials do not contain any appreciable amounts of highly unsaturated fatty acids unless they have been genetically modified. The phospholipids (commonly called lecithins) are routinely recovered from these oilseeds as a by-product of the vegetable oil extraction process. For example, in the production of soybean or canola oil, the beans (seeds) are first heat-treated and then crushed, ground, and/or flaked, followed by extraction with a non-polar solvent such as hexane. Hexane removes the triacylglycerol-rich fraction from the seeds together with a varying amount of polar lipids (lecithins). The extracted oil is then de-gummed (lecithin removal) either physically or chemically as a part of the normal oil refining process and the precipitated lecithins
recovered. This process however has two disadvantages: (1) the seeds must be heat- treated before extraction with hexane, increasing the processing cost, and increasing undesirable oxidation reactions and denaturing the protein fraction, thereby decreasing its value as a by-product; and (2) the use of the non-polar solvents such as hexane also presents toxicity and flammability problems that must be dealt with.
The crude lecithin extracted in the "de-gumming" process can contain up to about 33% oil (triacylglycerols) along with sterols and glucosides. One preferred method for separating this oil from the crude lecithin is by extraction with acetone. The oil (triacylglycerols) is soluble in acetone and the lecithin is not. The acetone solution is separated from the precipitate (lecithin) by centrifugation and the precipitate dried under first a fiuidized bed drier and then a vacuum drying oven to recover the residual acetone as the product is dried. Drying temperatures of 50-70°C are commonly used. The resulting dried lecithins contain approximately 2-4% by weight of oil (triacylglycerols). Process temperatures above 70°C can lead to thermal decomposition of the phospholipids. However, even at temperatures below 70°C the presence of acetone leads to the formation of products that can impair the organoleptic quality of the phospholipids. These byproducts can impart musty odors to the product and also a pungent aftertaste.
What is needed is an improved process for effectively recovering polar lipids and phospholipids rich in omega-3 and omega-6 HUFAs from biomaterials that enables the use of these fatty acid in food, nutritional supplement, pharmaceutical and cosmetic applications. Furthermore the fractions are needed as an ingredient in feed for companion animals and in aquaculture.

DETAILED DESCRIPTION OF THE INVENTION
Because of their bipolar nature, polar lipids (including phospholipids) are of significant commercial interest as wetting and emulsifying agents. These properties may also help make HUFAs in the phospholipids more bioavailable, in addition to enhancing their stability. These properties make phospholipids ideal forms of ingredients for use in nutritional supplements, food, infant formula, pharmaceutical, and cosmetic applications. Dietary benefits of phospholipids include both improved absorption and improved incorporation. Phospholipids also have a broad range of functionality in the body in that they are important cell membrane constituents, they are good emulsifiers, they can act as intestinal surfactants, serve as a choline source and as a source of HUFAs.
EPA, DHA, and ARA are normally produced for the nutritional supplement market and food uses through the extraction (by cooking) of fish (EPA and DHA) such as menhaden, tuna or salmon, or hexane extraction of fungal biomass (ARA) from the genus Mortierella. The phospholipids in both processes are removed in a later degumming step that produces a waste material comprising a complex mixture of neutral lipids, sterols,
glucosides and phospholipids. This material is normally sold to the domestic animal feed industry to dispose of it.
Besides fish and fungal biomass, there are microbial sources of DHA and DPA(n-
6). For the present invention, useful microbes can be selected from fungi, microalgae, protozoa or bacteria. These organisms can be selected from the groups including the
Stramenopiles, Thraustochytriales, Chrysophyceae, Xanthophyceae, Bacillariophyceae,
Dinophyceae, Phaeophyceae, Rhodophyceae, Chlorophyceae, Euglenophyceae,
Cryptophyceae, Oomycetes, Chytridomycetes, or Zygomycetes. Useful microbes can also be selected from the group of genera consisting of Mortierella, Mucor, Phycomyces, Rhizopus, Pythium, Ochromonas, Nitzschia, Phaeodactylum, Skeletonema, Fucus,
Platymonas, Achyla, Phytophera, Schizochytrium, Thraustochytrium, or
Crypthecodinium. Microorganisms are good sources of phospholipids because they can be grown in culture in a manner that optimizes phospholipid production and minimizes triglyceride (oil) production. On the other hand the methods used in this invention allow both oil and phospholipids to be recovered separately in forms that can be used directly in food, feed, nutritional supplements, cosmetic or pharmaceutical application.
DHA, EPA and ARA phospholipids can be recovered from fish, microalgae, or fungi through the degumming process described above. However as noted this produces a complex material containing many other compounds including neutral lipids, sterols, glucosides, etc
A preferred embodiment of the present invention is to use alcohol and centrifugation to recover the omega-3 and/or omega-6 HUFA-rich phospholipids. Preferred methods for this recovery are described in the following references, which are incorporated by reference herein in their entirety: i. PCT Application Serial No. PCT/USO 1/12047, entitled "Method for the
Fractionation of Oil and Polar Lipid-Containing Native Raw Materials" filed April 12, 2001; ii. PCT Application Serial No. PCT/USOl/12049, entitled "Method For The Fractionation Of Oil And Polar Lipid-Containing Native Raw Materials Using Water-Soluble Organic Solvent And Centrifugation" filed April 12, 2001.
Once the omega-3 and/omega-6 rich phospholipid fractions have been extracted by these preferred processes, they can be used directly as ingredients or they can be purified further and even separated into phospholipid classes by well-known techniques
such as different forms of chromatography, molecular distillation, and special refining techniques. Polar lipid groups phosphatidylcholine, phosphatidylserine, phosphatidylethanolamine, phosphatidylinositol, and sphingolipids. The phospholipid rich polar lipids or the purified phospholipid rich fractions can also be mixed with another lipid or oil such as fish lipids, microbial lipids, vegetable lipids, GLA-containing lipids, SDA-containing lipids and mixtures thereof, or be mixed with another phospholipid fraction (lecithin) such as soy or egg yolk lecithin, sunflower lecithin, peanut lecithin or mixtures thereof prior to use as a nutritional supplement, feed or food ingredient. These mixtures of phospholipids can also be incorporated into creams or lotions for topical applications (e.g. treating of skin conditions) or skin lesions induced by bums, UV- irradiation or other skin damaging processes. The mixtures can also be processed to produce a liquid or spray-dried dietetic product or fat emulsion for treating cachexia and severe fat malabsorption or for treatment of H. pylori infection of the gastrointestinal tract or incorporated into aerosol sprays for treating chronic inflammatory disease states of the lung (e.g., COPD, asthma, cystic fibrosis).
Advantages of the present invention including providing omega-3 and/or omega-6 ΗUFAs in a more bioactive and functional form (phospholipid) than the triglyceride form and include a better process (e.g., a) no need for heat treatment; b) no use of toxic solvents (like hexane) and c) no artifacts and off-flavors due to the use of acetone) for recovering these phospholipids from oilseeds and microbes. The EPA, DΗA, DPA(n-3), DPA(n-6), eicosatetraenoic acid and/or ARA content of the total fatty acids of the polar lipid fractions and comprise at least two weight percent of the total fatty acids of the polar lipid fraction, more preferably greater than 5 weight percent, more preferably greater than 10 weight percent, and most preferably greater than 20 weight percent of total fatty acids in the polar lipid fraction.
EXAMPLE
Example 1
Phospholipids were extracted from salmon, salmon roe, Black tiger prawns, squid, Schizochytrium sp, and the total fatty acid content of the phospholipids was determined by gas chromatography. The results are presented in Table 1. As can be observed the phospholipid fraction of these biomaterials can be used to deliver omega-3 and/or omega-
6 HUFAs and in this form these bioactive fatty acids should be more stable, more bioavailable, and more functional.
