1. A method for extracting seed oil from Punica granatum seeds to formulate a stabilized seed oil, said method comprising: separating Punica granatum seeds;drying said Punica granatum seeds;cleaning said Punica granatum seeds;flaking said Punica granatum seeds, wherein said flaking comprises tempering said seeds to 12 to 16% moisture content;extracting Punica granatum seed oil from said flaked Punica granatum seeds using solvent extraction process on a counter-current extractor using isohexane mixed with antioxidants selected from at least one of the group consisting of mixed tocopherols, natural antioxidants, and synthetic antioxidants; andstabilizing said Punica granatum seed oil. 2. The method of claim 1, wherein said drying said Punica granatum seeds is initiated for a duration and temperature sufficient to achieve a free fatty acid content of less than 0.5%. 3. The method of claim 1, wherein said drying said Punica granatum seeds comprises placing said Punica granatum seeds at a set depth of about ½″, drying at a set temperature of between 80-110° C., and drying for at least three hours. 4. The method of claim 1, wherein said drying said Punica granatum seeds comprises drying until said Punica granatum seeds contain 5-8% moisture content. 5. The method of claim 1, wherein said flaking said Punica granatum seeds comprises: pre-heating said tempered seeds to 50±3° C. in a cooker section of a cooker pre-press; andflaking said tempered seeds using a roller gap width setting of 0.2 mm. 6. The method of claim 1, wherein said stabilizing of said Punica granatum seed oil comprises water washing and caustic refining. 7. The method of claim 6, wherein said caustic refining comprises heating to 65° C. and adding 0.1% phosphoric acid, mixing and adding sodium hydroxide at 1 to 4% of starting oil weight. 8. The method of claim 6, wherein said water washing refining comprises heating to 40 to 50° C. and centrifuging to remove impurities, followed by adding 15% water (w/w) and mixing at 75° C., followed by recovering oil from said water by centrifugation. 9. The method of claim 1, further comprising: deodorizing said Punica granatum seed oil; andwinterizing said Punica granatum seed oil. 10. The method of claim 9, wherein said deodorizing comprises heating said Punica granatum seed oil to a temperature range between 180-210° C., cooling said Punica granatum seed oil to 40-90° C. and filtering said Punica granatum seed oil through a coarse filter. 11. The method of claim 6, wherein said stabilizing of said Punica granatum seed oil further comprises bleaching. 12. The method of claim 11, wherein said bleaching comprises applying heat, adding citric acid and mixing. 13. The method of claim 11, wherein said bleaching comprises using a filter aid, clay or activated carbon. 14. The method of claim 13, wherein said filter aid is selected from cellulose acetate and a synthetic amorphous micronized silica hydrogel. 15. The method of claim 11, wherein said bleaching comprises adding clay or activated carbon to said Punica granatum seed oil at 0.5% to 5% w/w at 75 to 115° C. and mixing for 10 to 60 minutes in a reactor under full vacuum. 16. The method of claim 11, further comprising: deodorizing said Punica granatum seed oil; andwinterizing said Punica granatum seed oil. 17. The method of claim 16, wherein said deodorizing comprises placing said seed oil under a vacuum pressure of 18-28 mm Hg after bleaching.
