The present disclosure relates methods and systems for refining grain oil compositions using water, and related compositions produced therefrom. The present disclosure also relates to methods of using grain oil derived from a fermentation product in an anti-foam composition and/or feedstock to make diesel.

Disclosed are methods for separating non-soy plant materials to produce a fat-enriched fraction, a reduced-fat plant extract, reduced-fat plant protein compositions, a crude oil, plant gums, a degummed oil and a protein-fat sediment. Also disclosed are food products containing or prepared from the reduced-fat extracts, fat-enriched fraction, gums, oils, protein-fat sediments and reduced-fat protein compositions.

A method is disclosed for recovering lipids from microbial biomass, and for producing lipids. In the method, an aqueous suspension includes fermentation broth containing oleaginous yeast biomass which is subjected to hydrothermal treatment and lipids are recovered from the biomass by solvent extraction.

A method and an plant for separating wax from a dried wax coated plant material, comprising mechanically processing the plant material in a dry process by using an apparatus adapted for deforming at least the outer surface of the plant material, so that the wax coating is cracked and released from the remaining, partly de-waxed, plant material; separating the plant material in a separator into a portion A comprising plant material with a relatively high content of cracked and released wax coating and a relatively low content of the remaining, partly de-waxed, plant material, and a portion B comprising respectively a relatively low content cracked and released wax coating and a relatively high content of the remaining, partly de-waxed, plant material; liquefying the wax contained in portion A, and separating the liquefied wax from the remaining, partly de-waxed, plant material in portion A.

A method of extracting CBD, THC, desirable oils, and other compounds from the cannabis plant includes drying the plant, grinding or chopping the plant, mixing the resulting pieces of the plant with a fluid to form a mixture, circulating the mixture through a controlled cavitation reactor to liberate CBD, THC, desirable oils, and other compounds from the pieces, and separating the liberated CBD, THC, desirable oils, and other compounds from the fluid. The method may be used as an adjunct to or in combination with traditional extraction techniques such as leaching to increase yields.

A method for recovering fish oil from aquatic biomass under cold conditions, the method comprising the steps of; providing an aquatic biomass; producing a minced aquatic biomass by mincing the aquatic biomass; providing an aqueous suspension of the minced aquatic biomass by mixing and/or homogenizing the minced aquatic biomass in an aqueous solution; adjusting the pH of said aqueous suspension to an extreme high pH or an extreme low pH; separating the aqueous suspension into a supernatant comprising a lower density emulsion fraction substantially comprising oil, aqueous solution and emulsified proteins, and a higher density fraction comprising substantially solubilized proteins, and optionally a pellet comprising collagenous components; collecting the lower density emulsion fraction; separating the lower density emulsion fraction into an oil phase and an aqueous phase; and collecting the oil from said oil phase.

Disclosed herein are processes for obtaining a microbial oil comprising one or more polyunsaturated fatty acids (PUFAs) from one or more microbial cells by removing water from the cell fermentation broth or lysed cell composition before demulsification is conducted. Such process has the benefits of reduced demulsification time and reduced salt use. Further disclosed herein is microbial oil comprising one or more PUFAs that is recovered from microbial cells by the process described herein.

The invention relates to a method of making an oil product, said method comprising: (i) forming a suspension of flax seed hemp, or chia in water, (ii) heat treating the suspension; (iii) reducing the particle size of the suspension, for example by grinding; (iv) optionally adjusting the suspension pH to between pH 7 to 8, or to about pH 7.5; (v) filtering the suspension and (vi) adjusting the suspension pH to between pH 2 to 3.5, or about pH 2.5; and (vii) obtaining a retentate, preferably by centrifuging; and (viii) adding the retentate to a melted fat or melted fat blend to form an oil product.
