Patent ID: 8545924

Claim:
A process of preparing a canola protein product, which comprises: adding a calcium salt to supernatant from the precipitation of a canola protein micellar mass to provide a conductivity of about 5 mS to about 30 mS to form a calcium phytate precipitate, removing precipitated calcium phytate from the resulting solution to provide a clear solution, adjusting the pH of the clear solution to about 2.0 to about 4.0, concentrating the pH-adjusted clear solution to a protein content of at least about 50 g/L to produce a clear concentrated canola protein solution, optionally diafiltering the clear concentrated canola protein solution, optionally effecting a colour removal step, and drying the concentrated protein solution to produce a dried canola protein product, wherein said concentration and/or optional diafiltration step are effected in such manner that the dried canola protein product contains about 60 to less than 90 wt % (N×6.25) protein on a dry weight basis.
