Abstract:
1. A process for producing a protein isolate from an oilseed meal, said oil seed meal not having been subjected to extraction with a solvent to remove oil and said oil seed meal being provided by cold pressing at a temperature of 85° C. or less, comprising: mixing the oilseed meal with an aqueous solvent comprising water without any added salt to form a slurry; if phytic acid is present in the oil seed meal, treating the slurry with phytase at a temperature and a pH suitable for phytase activity; separating the slurry with a solid/liquid separation process to form: separating the liquid phase to form: subjecting the aqueous soluble protein phase to membrane filtration to obtain a protein solution; and drying the protein solution to obtain the protein isolate, said protein isolate comprising a mixture of proteins having a range of molecular weights, wherein the protein isolate comprises at least 90% protein (w/w) on a dry weight basis.
