A process for making olive oil having a high polyphenol content and, in particular a high hydroxytyrosol content, comprises the conventional steps of transforming (II) olives (1) into an oily must (5); of resolving (V) the later into an oily juice (7), from which a base olive oil (8) is obtained, and into an aqueous juice (6) containing most of the polyphenols; and of separating (VII) the vegetation water (9) from the aqueous juice (6). Moreover, according to the invention, steps are provided of removing water (XV) from the vegetation water (9), preferably by evaporation, so as to obtain a polyphenol-enriched concentrate (11); and of mixing (XIX) the concentrate (11) with the base olive oil (8), so as to transfer said polyphenols from the former to the latter and to obtain a final polyphenol-enriched oil (12), along with an exhausted concentrate (11′). The step of removing water causes a polyphenol concentration increase, to enhance their interphase transfer, and, at the same time, it causes a viscosity and density increase, which makes the water phase, during the contact with the oil, less prone to form emulsions than the methods of prior art. The high polyphenol concentration remarkably improves the organoleptic quality of the oil and makes the latter more stable, besides producing well-known advantageous effects for the consumer's health. According to further aspects of the invention, an apparatus is provided for making such oils, as well as a concentrate for use in olive oils and also in any other vegetable or animal food oil, in cosmetics, bio-repellent products and the like.

There is a method for extracting bio-oil from algal biomass, in particular oily microalgae, using solvents of a Deep Eutectic Solvents (DES) capable of producing a bio-oil with a low content of phospholipids and inorganic salts, mainly sodium chloride.

The present invention is directed to novel silane disulfide vegetable oils, a method of making the oils, their use in rubber compositions, and their use in tires.

A system and method for extracting botanical herbal oil is disclosed. The method includes washing plant material with liquid solvent forming a solvent-oil extract solution, pumping the solvent-oil extract solution to an atomizer, pumping vapor solvent to the atomizer, atomizing the solvent-oil extract solution with vapor solvent forming an atomized mixture, and vaporizing the atomized mixture to isolate the botanical herbal oil from the mixture. The system includes a first pressure vessel to chill a solvent, a second pressure vessel to wash plant material with liquid solvent forming a solvent-oil extract solution, an atomizer to mix the solvent-oil extract solution with vapor solvent forming an atomized mixture, a liquid transfer pump to pump the solvent-oil extract solution to the atomizer, a vapor transfer pump to pump the vapor solvent to the atomizer, and a vaporizer to vaporize the atomized mixture and isolate the botanical herbal oil.

The disclosed embodiments include systems and methods for the solvent extraction of a substance from a material. The disclosed systems include multiple tanks and an extraction column in communication with the tanks. Solvent transport is accomplished via pressure differentials that are established between or among tanks to cause the solvent to be transported between or among said tanks.

Disclosed herein are processes for reducing or eliminating emulsion during the process of obtaining a microbial oil comprising one or more polyunsaturated fatty acids (PUFAs) from one or more microbial cells by washing the fermentation broth with at least 1 amount of water. Further disclosed herein is microbial oil comprising one or more PUFAs that is recovered from microbial cells by at least one process described herein.

The present invention relates to an oil comprising at least one polyunsaturated fatty acid having at least 20 carbon atoms (LC-PUFA). It is found that LC-PUFA-containing oil are susceptible to gelling by formation of microscopic crystals during storage ultimately resulting in unfavorable quality and handling properties. This problem has been particularly observed with a microbial oil comprising at least about 25% by weight LC-PUFA and a moisture content of 0.2 to 5% by weight. Surprisingly, it has been found that a LC-PUFA-containing oil as described above is effectively stable and does not show gelling properties under conventional storage conditions, if the oil composition as such contains less than about 8% preferably less than about 5% by weight of free fatty acid in the residual moisture of the oil. Therefore, the present invention is directed to an oil comprising at least about 25% by weight LC-PUFA and a moisture content comprising less than about 8% preferably less than about 5% by weight of free fatty acid.

A method for extracting naturally occurring oil bodies (oleosomes) from a material containing naturally occurring oil bodies (oleosomes) includes the steps of dispersing the material containing oleosomes in an aqueous composition to thereby obtain an aqueous dispersion of material containing oleosomes, extracting oleosomes from the aqueous dispersion of material containing oleosomes to thereby obtain a crude oleosome extract and isolating crude oleosomes from the extract by drying the crude oleosome extract. The dried oleosome powder may be used with a personal care product, a pharmaceutical product or a food product.
