摘要:
The present invention contemplates the creation of a low fluoride oil processed from a phospholipid-protein complex (PPC) formed immediately upon a crustacean (i.e., for example, krill) catch. The process comprises disintegrating the crustaceans into smaller particles, adding water, heating the result, adding enzyme(s) to hydrolyze the disintegrated material, deactivating the enzyme(s), removing solids from the enzymatically processed material to reduce fluoride content of the material, separating and drying the PPC material. Then, using extraction with supercritical CO2 and ethanol as solvents, inter alia krill oil is separated from the PPC. In the extraction the krill oil can be separated almost wholly from the feed material. The products have low fluoride content. The manufacturing costs in the extraction process are relatively low.

This invention discloses new krill oil compositions characterized by having high amounts of phospholipids, astaxanthin esters and/or omega-3 contents. The krill oils are obtained from krill meal using supercritical fluid extraction in a two stage process. Stage 1 removes the neutral lipid by extracting with neat supercritical CO2 or CO2 plus approximately 5% of a co-solvent. Stage 2 extracts the actual krill oils by using supercritical CO2 in combination with approximately 20% ethanol. The krill oil materials obatined are compared with commercially available krill oil and found to be more bioeffective in a number of areas such as anti-inflammation, anti-oxidant effects, improving insulin resistances and improving blood lipid profile.

Process for recovery and separation of sugars and oil from plants where the stems and leaves of such plants have substantial levels of both sugars and oils.
摘要:
A method for degumming and/or refining crude oil containing impurities involving mixing the crude oil with degumming agents, i.e., water or acid, and subjecting the mixture to flow-through, hydrodynamic cavitation processing. The cavitational processing transfers impurities in the crude oil to a water phase for easier separation. The water phase may be separated from the oil phase by commonly available separation methods.

The present invention relates generally to the field of recombinant fatty acid synthesis, particularly in transgenic plants. The application describes genes involved in fatty acid synthesis and provides methods and vectors for the manipulation of fatty acid composition of plant oils. In particular, the invention provides constructs for achieving the integration of multiple heterologous genes involved in fatty acid synthesis into the plant genome, such that the resulting plants produce altered levels of polyunsaturated fatty acids. Also described are methods for enhancing the expression of fatty acid biosynthesis enzymes by co-expressing a silencing suppressor within the plant storage organ.

摘要:
A method for separating neutral and polar lipids from an oil of biological material, wherein the oil is fractionated using a mixture of a polar solvent comprising at least one carbon atom, water and an additional substance selected from the group consisting of: mono-, di- and oligosaccharides comprising from 3 to 10 monosaccharide units, said additional substance is present in an amount of at least 0.1 wt % calculated on the total weight of solvent, water and additional substance, to form at least two liquid fractions having different densities, wherein one fraction is rich in polar lipids and another fraction is rich in neutral lipids. An oil rich in polar lipids obtained from the method is disclosed, said oil I contains at least 40, preferably at least 50 lipid % polar lipids as calculated on the total amount of lipids in said oil and that the total amount of polar solvent and water in said oil is between 20 and 30 wt %. An oat oil containing high amounts of estolides of DGDG can further be obtained.
摘要:
A method for recovering lipids from microbial biomass, the method including providing wet microbial biomass which contains lipids to extraction without disrupting the biomass cell walls, and subsequently, extracting the wet microbial biomass with a liquid extractant at elevated temperature of at least 170° C. and elevated pressure. The combination of the temperature and pressure is such that the lipids in the cells are contacted with the extractant. Subsequently the extracted lipids are recovered from or with the extractant.
