PROBLEM To provide a composition comprising highly enriched PUFA or its alkyl esters while containing fatty acid esters of 3-MCPD at adequately low concentrations and to provide an efficient method for producing the composition. MEANS FOR SOLVING A composition that contains fatty acids or fatty acid alkyl esters as its major component, the composition containing highly unsaturated fatty acid or alkyl ester thereof, wherein the proportion of the highly unsaturated fatty acid in the constituent fatty acids of the composition is 50 area % or more and wherein the concentration of 3-MCPD as found upon analyzing the composition by American Oil Chemists' Society official method Cd 29b-13 assay A is less than 1.80 ppm.

The invention relates to a new solvent-free process for simultaneously obtaining phospholipids-enriched krill oil and neutral lipid enriched-krill oil containing DHA and EPA poly-unsaturated fatty acids and astaxanthin and krill meal. The process includes preheating fresh minced krill followed by melting of the lipids using live steam injection to obtain a press liquid and a solid fraction; centrifuging the press liquid to obtain a phospholipids-enriched emulsion phase; evaporating the water of the emulsion using a thin film evaporator to obtain phospholipids-enriched krill oil; centrifuging the resulting decanter liquid to obtain neutral lipids enriched krill oil and stickwater.

Systems and methods are provided for separating high value by-products, such as oil and/or germ, from grains used for alcohol production. In one embodiment, a method for separating by-products from grains used for alcohol production includes, subjecting milled grains to liquefaction to provide a liquefied starch solution including fiber, protein, and germ. The germ is separated from the liquefied starch solution. The separated germ is ground, e.g., to a particle size less than 50 microns, to release oil to provide a germ/oil mixture. Then, prior to fermentation, the oil is separated from the germ/oil mixture to yield an oil by-product. The pH of the germ/oil mixture can be adjusted to about 8 to about 10.5 and/or cell wall breaking enzymes or chemicals may be added to help release oil from the germ. In one example, the oil yield is greater than 1.0 lb/Bu.

A multi stage process for separating oil, protein, fiber and clean water from a stream containing whole stillage byproduct from ethanol production is disclosed. In a first step, fibers are separated in a two-step process that includes a plate separator and a press. In a subsequent step, the liquid stream separated from the fibers and contains oil, protein and water is treated with a composition that causes the protein to gel. The liquid stream is then processed in a phase separator that drains the oil by gravity, removes the water by an impeller under pressure and removes the solidified protein using a scroll.

The present invention provides a composition based on a starch powder (such as flour), wheat germ, SiO.sub.2, MgO, Al.sub.2O.sub.3, Fe.sub.2O.sub.3, and K.sub.2O. This composition is extremely useful in treating acid related disorders and reducing the acidity, removing water, deodorizing, from plant oil and extending the oils shelf life of 3-5 years instead of the average one-year available.

A composition of matter comprises a shelf stable, partially defatted supercritical CO.sup.2 fluid solvent extracted whole grain flour derived from a cracked biomass of perilla frutescens, the flour comprising minerals and 2 to 8 percent of native seed oil, 35 to 45 percent protein, and 35 to 45 percent fiber.
