The present disclosure provides for improved oilseed extraction methods using sequential extractions with polar solvents and non-polar solvents or extractions with an azeotrope of a polar solvent and a non-polar solvent to produce oilseed meal concentrates having increased protein content and reduced soluble carbohydrate and anti-nutritional compound content.

This invention relates to a process for the continuous production of vegetal protein concentrates by removing the soluble carbohydrates by an aqueous alcohol from a defatted vegetable material said process requiring no frequent production interruptions for cleaning operations. The innovative process includes the steps of removing at least a fraction of the soluble carbohydrates by solvent extraction, the solvent being aqueous alcohol, to obtain a solvent wet protein rich vegetable material and a miscella; removing the aqueous alcohol form the solvent wet protein rich vegetable material to obtain a vegetable protein concentrate; wherein the solvent extraction takes place in a moving screen solvent extractor equipped with a cleaning means of the moving screen on its return journey and for which no plugging takes place for extended period of time.

A method provides for removing oil content from a source material and extracting protein from the source material prior to generating a protein concentrate, including decorticating the source material, the source material having a protein and an oil content therein, the decorticating to remove a cortex from the source material. The method includes creating a flour from the source material having the cortex removed therefrom, removing at least a portion of the oil content from the flour by generating a solvent mixture by mixing the flour with a solvent and extracting a de-oiled flour from the solvent mixture, including oil and sugars extracted from the flour. The solvent may include supercritical CO2, subcritical CO2, ethanol, or a combination thereof. The method includes drying the de-oiled flour using at least one dryer and extracting a protein concentrate from the de-oiled flour.

A system and method for vicine/covicine removal includes generating a feed stock from a plant-based protein source, the plant-based protein source having anti-nutritionals disposed therein, including vicine and covicine. The system and method includes generating an ethanol slurry by combining the feed stock with an ethanol wash containing a first volume of ethanol and processing the ethanol slurry through an extractor to generate an ethanol matrix and a feed stock mass. The method and system further includes providing the feed stock mass to a desolventizer and generating a desolventized feed stock mass therefrom. Therein, the method and system includes drying the desolventized feed stock mass to generate a clean feed stock with at least a portion of the vicine/covicine removed therefrom.

A dry fractionation method and system provides for generating a protein concentrate product therefrom. The method and system includes milling a plant-based flour to generate milled flour and generating a first protein concentrate from the milled flour using an air classifier. The method and system includes processing the first protein concentrate to generate a protein rich curd and generating a neutral hydrolyzed protein slurry by mixing the protein curd with a base, water and enzymatic cocktail. The method and system includes generating a homogenized protein slurry from the protein slurry and generating a cooled protein slurry by pasteurizing the homogenized protein slurry. Therein, the method and system provides for extracting the protein concentrate product from the cooled protein slurry.

Pulse proteins of reduced astringency are obtained by fractionating pulse protein products which are completely soluble and heat stable in aqueous media at acid pH value of less than about 4.4 into lower molecular weight, less astringent proteins and higher molecular weight, more astringent proteins.

A gluten free native rapeseed protein isolate comprising <10 ppm gliadin and processes to obtain the gluten free native rapeseed protein isolate comprising <10 ppm gliadin.

A method of identifying a selected pollination window in a Poaceae crop by monitoring one or more environmental parameters and identifying a selected pollination window based upon the monitored parameters. The correct selection of parameters has been shown to markedly increase seed set, yield, and/or other desirable characteristics, including but not limited to preferred content of oil, starch, protein, and/or other nutritional components. Parameters may include one or more of: temperature, relative humidity, and vapor pressure deficit.

A method and system provides for for de-oiling and extracting protein from chickpeas prior to generating chickpea protein concentrate. The method and system includes receiving a chickpea flour generated from the chickpeas, including having cortex material removed from the chickpeas and generating an ethanol mixture by mixing the chickpea flour with ethanol to remove at least a portion of the oil content from the chickpea flour. The method and system includes separating the ethanol mixture into a de-oiled chickpea flour and an ethanol recycling stream having organics from the chickpea flour absorbed therein. Therein, the method and system includes extracting a protein concentrate from the de-oiled flour.

Methods of manufacturing products from material comprising oilcake, compositions produced from materials comprising processed oilcake, and systems for processing oilcake are provided herein. A product is produced by a method comprising de-solubilizing protein in a first material comprising oilcake to produce a processed material comprising an insoluble protein fraction by extruding the first material in a pressure range of 10 bar to 80 bar. The processed material is hydrolyzed to produce a mixture comprising the insoluble protein fraction and a hydrolyzed fraction. The insoluble protein fraction is separated from the hydrolyzed fraction. The insoluble protein fraction is processed into the product by extruding the insoluble protein fraction in a pressure range of 10 bar to 80 bar.
