A process for obtaining free fatty acid and/or free fatty acid ester, including separating a liquid mixture containing the free fatty acid and/or the fatty acid ester by contacting a vapor of the liquid mixture in a column of a distillation apparatus with condensate formed from the vapor running downward. Heat and mass transfer takes place between the vapor and the condensate on column internals. The column has at least 10 theoretical plates and the separation is conducted with a pressure drop between the top and bottom of the column of p of 3.3 mbars. Appropriately, the liquid mixture, contains polyunsaturated fatty acid, preferably omega-6 or omega-3 fatty acid and/or alkyl monoesters and/or glycerol monoesters. In one embodiment the column has at least 30 theoretical plates and the separation is conducted with a pressure drop p between 3.5 mbar and 6 mbar.

The present invention relates to a process for winterizing crude fish oil by an improved winterization process, wherein a solubilizing agent is added to the fish oil prior to the winterization. The solubilizing agent is preferably a fat-soluble edible organic compound, such as fatty acids or fatty acid mixtures. The invention further relates to compositions obtainable by the process.

Lipid compositions derived from a solvent-extracted distillers oil of a dry grind ethanol process and lipid compositions included in cosmetic products, personal care products, skin care products, nutraceuticals, bio fuels, bio-lubricants, oleo chemicals, nutritional products, other bio-products, and animal feed compositions. Concentrations of lipid components.

One or more techniques are disclosed for a process of preparing stearic acid from animal and/or plant sources may comprise: 1) deodorizing and distilling a fat; 2) concentrating fatty acids of the fat; and 3) hydrogenating the fatty acid to provide stearic acid. The process may include the use of co-products from plant and/or animal sources. The process may also include distilling the stearic acid to provide palmitic acid and/or fully hydrogenated fatty acid. Tallow fatty acid, vegetable fatty acid, stearic acid, and palmitic acid prepared from the process described are also disclosed.

Provided herein are systems and methods for the facile extraction and purification of oils from plant material, including cannabis and hemp. The systems and methods herein are versatile, and may utilize a wide range of solvents to extract oils from a variety of plant-based material. Further, the provided systems and methods are closed loop, reducing the loss solvent and decreasing the risk of safety concerns such as human exposure to solvent chemicals or explosion of volatiles. In some embodiments, the systems and methods remove impurities from the extracted oils, for example waxes or other precipitates, and provide a higher purity and higher quality extract.

Oils and fats containing 10 to 80 mass % of 1,3-distearoyl-2-oleoylglycerol (SOS) and including a triple chain length -type SOS crystal are provided. In the measurement of the X-ray diffraction of the triple chain length -type SOS crystal, the diffraction peak A corresponding to spacing of 3.95 to 4.05 , the diffraction peak B corresponding to spacing of 3.80 to 3.95 , the diffraction peak C corresponding to spacing of 3.70 to 3.80 , and the diffraction peak D corresponding to spacing of 3.60 to 3.70 are observed. The ratio of the diffraction intensity of the diffraction peak C to the diffraction intensity of the diffraction peak D is 0.35 or less.

A method of treating a mother having postpartum depression, comprising administering to the mother a composition comprising a plurality of mixed self-assemblies comprising: i) at least 50 wt % of a soyasaponin, and ii) allopregnanolone.

A chocolate having good solidification properties, a high mold releasability and a high crystal stabilization rate, said chocolate being obtained by using an oil or fat composition wherein StOSt and POP triglycerides are contained each in a definite amount or more and StLSt, PLP, StStO and PPO triglycerides are contained each in a definite amount or less. As a result, the productivity of the chocolate can be increased.
