A process for isolating a sunflower oleosome fraction; comprising a) Grinding sunflower seeds in aqueous solution and obtaining a sunflower seed slurry with pH of more than 7.2, wherein a reducing agent and/or an acidulant is added during grinding and/or wherein it is added to the slurry; and b) isolating a sunflower oleosome fraction. Invention describes a sunflower oleosome fraction or a concentrate comprising isolated and/or washed oleosomes and a reducing agent and/or an acidulant in an amount of from 0.10 to 1.50 wt %. It describes the use of a reducing agent and/or an acidulant for prevention of green coloring.

Provided are methods and systems for recovering protein product powder, purified water and omega-3 oil from an animal tissue. The methods and systems use high throughput extraction filtration separation systems. Animal tissue, for example fish, and organic solvent are directly or indirectly transferred into one of the optional extraction or filtration systems. The extraction-filtration systems provide a high degree of filtration performance and product washing efficiency. Each system ultimately yields a product wet cake that includes the protein product. The protein product wet cake is then further dried in a drying unit to yield the final protein powder product. In each system, the process filtrates undergo further processing by filtration and distillation to recover the organic solvent and separate out the omega-3 fish oil. The recovered organic solvent can be recycled back into the process. Solid protein product powder is thus recovered, along with omega-3 oil, purified water and recovered solvent.

A system for treating whole stillage includes a stillage tank, a separation system in communication with the stillage tank and configured to separate the whole stillage into a wet cake portion and a thin stillage portion, and a primary filtration system in communication with the separation system. The primary filtration system can be configured to separate the thin stillage into a primary concentrate and a primary permeate. A secondary filtration system in communication with the primary filtration system can be configured to further purify the primary permeate. A water reclamation system in communication with the primary and/or secondary filtration system can remove water from the permeate. An additive can be added to the primary permeate to precipitate phosphorus-containing minerals and corn oil can be advantageously extracted from the primary concentrate. Protein-enriched animal feeds can be generated from dehydration of the primary concentrate.

A method for producing peanut oil, peanut oil produced thereof, and use of hydrolases to improve sensory property of peanut oil. Said method includes the steps of providing a peanut water mixture; adding one or more hydrolases to the peanut water mixture; hydrolyzing the peanut water mixture to produce hydrolyzed peanuts; drying the hydrolyzed peanuts to form dried hydrolyzed peanuts; roasting the dried hydrolyzed peanuts to form roasted peanuts; pressing the roasted peanuts to produce crude peanut oil; and filtering the crude peanut oil to form peanut oil.

An apparatus and process for extracting organic molecular compounds from plant material and concentrating those into a viscous oil, the process supported by a machine architecture that heats, cools, and stirs a cooking mixture of plant material and a consumable solvent oil, the viscous oil suitable for use in sublingual tinctures, food products, and topical salves.

The present invention concerns a process for producing fermentation products, such as ethanol, and a biogas unit, wherein a yield enhancing composition comprising at least one, at least two, at least three, at least four, or at least five different types of enzymes and/or at least one, at least two, at least three, at least four, or at least five different microorganisms is added to the whole stillage that is fed to the slurrying step and/or the biogas unit, outflow of the biogas unit before being mashed in the slurrying step; thin stillage that is fed to the slurrying step, residual materials resulting from purification of the oil and/or of the protein product that are fed to the biogas unit, wet cake that is fed to the slurrying step and/or fed to the biogas unit, added to the biogas unit, and/or biomass added to any one of the preceding steps.

An object is to provide a vegetable oil and/or fat which can be used as a substitute for an emulsifier that is usable in water-in-oil emulsions with a simple method without requiring unique facilities for producing water-in-oil emulsions. As a specific solution, a shea butter fraction obtained by fractionating shea butter under specific conditions is blended into any oil and/or fat, thereby enabling to provide a substitute for the function of emulsifiers in water-in-oil emulsions. In addition, the water-in-oil emulsion obtained by the present method is such that changes in physical properties over time as well as immediately after preparation of the emulsion can be suppressed.
