FRACTIONATION AND TREATMENT OF FEED MEAL FROM OILY SEEDS Russian patent published in 2006 - IPC A23J1/14 A23K1/14 A23K1/18 

FIELD: food and feed processing industry, in particular production of food proteins and feed meal.

SUBSTANCE: method of water extraction and fractionation includes blending of raw material from rape or canola seeds with water in concentration of 10-50 mass/vol % under mild extractive conditions to form aqueous mixture containing aqueous extract including extracted protein, fine fragments of solid phase of seed core cells and fiber material. Further obtained aqueous extract is separated from solid phase residue by filtration or screening through screen to produce filtrate including extracted protein and fine fragments of solid phase of seed core cells residue contains at least 200 mass % of protein calculated as dry matter of solid phase residue. Then said aqueous extract and fine fragments of solid phase of seed core cells are treated with enzyme at 10-70°C to produce extracted dephytinized high protein fraction comprising at least 30 mass % of total protein amount containing in raw materials. Extracted dephytinized fraction is treated by conditioning thereof at not less than 80°C for at least 1 min to induce coagulation of protein containing therein. Further extracted fraction is separated to produce solid phase and liquid.

EFFECT: method for production of value feed product for ruminants without side product or wastes.
