A process for extraction of edible protein from corn germ. The process includes providing a defatted corn germ with a fat concentration of less than about 5% by weight, milling the corn germ to a granulation of less than about 100 US mesh at less than 180°F, preparing a slurry from the milled corn germ, extracting a edible protein solution from the slurry, recovering the edible protein by precipitating agents (ethanol, acids), and drying the edible protein. The resulting food is 80% to 90% protein.

La présente invention concerne un traitement destiné à l'extraction d'une protéine comestible contenue dans le germe de maïs. Selon ce procédé, on commence par prendre un germe de maïs délipidé dont la teneur pondérale en lipide est inférieure à environ 5%, puis on moud le germe de maïs jusqu'à atteindre une granulation d'un calibre inférieur à environ 100 mesuré au tamis US à une température inférieure à 180°F. À partir du germe de maïs moulu, on élabore une bouillie liquide dont on extrait une solution de protéine comestible. Enfin, pour recueillir la protéine comestible, on la précipite avec des agents tels que l'éthanol et des acides, et on la fait sécher. L'aliment résultant est à 80 90 % une protéine.
