Ultra High Pressure Extraction of Plant Proteins

Drying non-mammalian proteins like plant proteins using a combined heating and drying process. The method involves atomizing and heating the protein liquid feed in a steam atmosphere at high pressures (5 barg or more) before direct drying in a spray dryer. This provides functionalized, texturized protein powders with reduced microbial loads and increased viscosity compared to conventional methods. The high pressure primary atomization and heating in the steam infusion chamber allows functionalization and concentration without dilution before drying.

A method for extracting high-value active compounds from wheat sprouts using ultra-high pressure sub/supercritical fluid extraction. The extraction process involves grinding wheat sprouts into a fine powder, injecting the powder into a reactor, and using sub/supercritical fluid at ultra-high pressure to extract the desired compounds. The extracted compounds are then concentrated under reduced pressure to produce a high-purity extract. This approach enables efficient extraction of polyphenols, flavonoids, and other bioactive compounds from wheat sprouts, with enhanced yield compared to conventional extraction methods.

A process for producing high-purity protein preparations from plant biomass through enzymatic extraction. The method employs a buffer solution containing a reducing agent to extract proteins from plant materials, followed by mechanical lysis, enzymatic treatment, and separation steps. The extraction process maintains protein purity of at least 80% while achieving optimal protein recovery. The resulting protein preparations can be formulated into a wide range of food products with minimal impurities.

A process for extracting high-quality protein isolates from plant materials like oilseeds, legumes, and lentils that contains high levels of oils, fats, and lipids. The process involves pre-treating the raw material to remove impurities, then extracting proteins using an aqueous solvent. The extract is then fractionated, concentrated, and purified using a sequence of declining polarity organic solvents. This allows isolating the proteins without co-extracting the oils and fats. The resulting isolates have high protein content, low carbohydrates, low phenolics, and no high-carbon solvents. They also retain native protein properties for food applications.

A novel approach to producing high-quality protein concentrates from forage crops like alfalfa that can be used as feed ingredients in animal nutrition. The concentrate is produced through a process that preserves the natural nutritional value of the forage while eliminating its undesirable anti-nutritional compounds. The process involves extracting and concentrating plant juice, then drying it directly to produce a protein-rich concentrate. This concentrate can be used as a feed ingredient in animal nutrition, particularly for livestock like pigs and poultry, while maintaining its nutritional value compared to traditional protein concentrates.
