The present invention refers to a process for reducing the amount of undesired components in an oil composition, particularly in an oil composition comprising omega-3 polyunsaturated fatty acids. The process of the present invention provides efficient removal of undesired water-soluble (hydrophilic) components and undesired fat-soluble (lipophilic) components from an oil composition in order to obtain a purified concentrate, e.g. a highly purified concentrate enriched in omega-3 polyunsaturated fatty acids.

A solid avocado oil is characterized in that its palmitic acid content in relation to total fatty acids is between 15 and 35% and its complete melting point is within a range of from 20 to 50? C., the avocado oil being obtained from avocado of a variety selected from the list consisting of Hass, Fuerte, Bacon, Pinkerton, Ettinger, Lula, Ryan, Barker, and/or Peruano. A cosmetic or pharmaceutical composition is characterized in that it comprises, in a cosmetically or pharmaceutically acceptable vehicle, a solid avocado oil according to the invention. A method for obtaining a solid avocado oil is characterized in that it is carried out on fresh or dehydrated fruit, crude avocado oils, or co-products from the refining or dewaxing of crude avocado oils.

The invention relates to a lipid extract of the seeds of passion fruit, Passiflora incarnata and/or Passiflora edulis, preferably P. edulis, characterised in that said lipid extract is an oil of passion fruit seeds concentrated in its unsaponifiable fraction, containing between 3 wt. % and 100 wt. % of unsaponifiable matter in relation to the total weight of the extract. The invention also relates to a method for preparing such an extract and to a composition comprising said extract, especially for the use thereof in a dermatological or pharmaceutical composition or as a food.

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.

The present invention relates to a method of admixing a volume of water in which acid- or base-forming compounds are contained and whose volume fraction is >5% by volume in the ratio to be purified lipid phase and/or in a volume ratio that allows the formation of a water phase in order to separate hydratable mucilage from a lipid phase, to purify a lipid phase and/or to obtain the hydratable mucilages.

The present invention provides compositions and methods related to the production and use of enzymes suitable for reducing the amount of steryl glycosides or saturated monoacyl glycerols in a lipid mixture.

An aqueous orthosilicate solution comprising m[SiO4.sup.4?]+nX.sup.1+ in an aqueous solution wherein X is an alkali metal cation selected from the group consisting of sodium or potassium; and wherein n is four to five times greater than m. The aqueous orthosilicate solution is made by adding silicon particles of less than about 3 cm and water to a pressure vessel followed by adding a molar excess of alkali caustic to the pressure vessel containing the silicon particles. The temperature in the vessel is maintained not to exceed about 190? F. while an aqueous orthosilicate solution is formed. Upon cooling the formed aqueous orthosilicate solution is recovery. Aluminum or CuO can be added during the initial heating.
