Various aspects of the disclosure relate to methods and systems for extracting plant oil from plant material. A system may comprise a microwave emitter, an extraction chamber, and a cooling chamber. Microwave radiation emitted by the microwave emitter may dielectrically heat a microwave absorbing agent, which may heat the plant oil of the plant material. Plant oil of the plant material may be volatized in the extraction chamber and may be directed into the cooling chamber to be condensed.

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.

The present disclosure is related to refining one or more grain oil composition streams (e.g., distillers corn oil or syrup) in a biorefinery to provide one or more refined grain oil products, where each grain oil product has targeted amounts of a free fatty acid component and the fatty acid alkyl ester component.

The present disclosure provides an extraction method of natural crocodile oil. The method improves the traditional ancient method of making oil, and includes: mixing crocodile fat with a traditional Chinese medicine bag and standing, then taking out the fat, and sequentially pulping and filtering. By using the above method, any extracts are not added without decolorization, the effective ingredients in the crocodile oil can be maintained to the greatest extent to the greatest extent, and therefore the method of the present disclosure is suitable for large-scale production. The present disclosure further provides the crocodile oil obtained by the extraction method. The crocodile oil is glittering and translucent, has no fishy smell, and can be preserved for a long time.

A process for production of biofuels from algae can include cultivating an oil-producing algae by promoting sequential photoautotrophic and heterotrophic growth. The method can further include producing oil by heterotrophic growth of algae wherein the heterotrophic algae growth is achieved by introducing a sugar feed to the oil-producing algae. An algal oil can be extracted from the oil-producing algae, and can be converted to form biodiesel.

A protein fraction and an oxidation stable fat fraction are recovered from poultry containing fat, bone and protein. The poultry is comminuted, mixed with a food grade acid at pH 3.6 to 4.4 to form a liquid protein fraction and a solid fat fraction. The liquid fraction is mixed with a food grade alkali to precipitate the protein.

Disclosed are techniques and systems for producing microbials having anaplerotic oils that are rich in odd-chain fatty acids, and other beneficial components, at higher concentrations than those present in other natural dietary sources of OCFA, at lower cost, and higher production yield. Such compositions can comprise pentadecanoic and heptadecanoic fatty acids. The techniques described herein include methods for producing and deriving such compositions rich in odd-chain fatty acids from microbials, including microalgae and yeasts/fungi.
