The present invention relates to lipid comprising docosapentaenoic acid and/or docosahexaenoic acid wherein the docosapentaenoic acid and/or docosahexaenoic acid may be preferentially esterified at the sn-2 position of triacylglycerol, and processes for producing and using the lipid.

The present invention provides a process for the enzymatic degumming of unrefined triglyceride oils, said process comprising: a) providing an unrefined triglyceride oil having a phosphorus content of at least 100 mg per kg of unrefined triglyceride oil; b) combining the unrefined triglyceride oil with water, lactic acid and enzyme to produce an oil-and-water emulsion, said enzyme being selected from phospholipase, lipid acyltransferase and combinations thereof; c) keeping the emulsion at a temperature of 20-90° C. for at least 10 minutes; and d) separating degummed triglyceride oil from the emulsion. This enzymatic degumming process is extremely effective in removing phospholipids, including non-hydratable phospholipids (NHP), from crude and other unrefined vegetable oils.

A method for preparing field muskmelon oil includes the following steps: S1, removing foreign matter, including: removing the foreign matter in field muskmelon seeds; S2, low-temperature pressing, including: performing the low-temperature pressing on the field muskmelon seeds after removing the foreign matter in step S1 to obtain an oil residue mixture; S3, filtering and removing impurities: filtering the oil residue mixture obtained by the low-temperature pressing in step S2 to remove the impurities to obtain a primary oil; and S4, centrifugal separation, including: centrifugally separating the primary oil obtained by filtering and removing impurities in step S3 to obtain the field muskmelon oil. The new method avoids using high-temperatures resulting in optimal yield of nutritional content and no harmful byproducts.

A method for producing a carotenoid enriched fatty acid composition includes: reacting an oil including free fatty acids and carotenoids with a basic solution; withdrawing, separately from the oil, an extraction solution including at least a portion of the free fatty acids, at least a portion of the carotenoids, and the basic solution; acidifying the extraction solution to produce an aqueous phase and a fatty acid phase, the fatty acid phase including the free fatty acids and the carotenoids of the extraction solution; and separating the fatty acid phase from the aqueous phase.
