A process of preparing a canola protein isolate having a protein content of at least 90 wt% (N x 6.25) on a dry weight basis, comprising: (a) optionally (i) partially concentrating the supernatant from the precipitation of a canola protein micellar mass to a concentration of 50 g/L or less, or (ii) concentrating the supernatant from the precipitation of a canola protein micellar mass to a concentration of at least 50 g/L; (b) adding a calcium salt (i) to supernatant from the precipitation of canola protein micellar mass in the absence of optional step (a) to provide a conductivity of 5 to 30 mS to form a calcium phytate precipitate, or (ii) to the partially concentrated supernatant or concentrated supernatant in the presence of optional step (a) to provide a conductivity of 2 to 30 mS to form a calcium phytate precipitate, (c) adjusting the pH of the solution resulting from step (b) without removal of the calcium phytate precipitate to 2.0 to 4.0 to dissolve the precipitate and form a pH-adjusted clear solution, and (d) in the absence of optional step (a) or in the presence of step (ai), concentrating the pH-adjusted clear solution to a concentration of at least 50 g/L to form a clear concentrated canola protein solution, (e) optionally diafiltering the clear concentrated canola protein solution, (f) optionally effecting a colour removal step on the optionally diafiltrated clear concentrated canola protein solution, and (g) drying the optionally discoloured and optionally diafiltered clear concentrated protein solution. (a) optionally (i) partially concentrating the supernatant from the precipitation of a canola protein micellar mass to a concentration of 50 g/L or less, or (ii) concentrating the supernatant from the precipitation of a canola protein micellar mass to a concentration of at least 50 g/L; (i) partially concentrating the supernatant from the precipitation of a canola protein micellar mass to a concentration of 50 g/L or less, or (ii) concentrating the supernatant from the precipitation of a canola protein micellar mass to a concentration of at least 50 g/L; (b) adding a calcium salt (i) to supernatant from the precipitation of canola protein micellar mass in the absence of optional step (a) to provide a conductivity of 5 to 30 mS to form a calcium phytate precipitate, or (ii) to the partially concentrated supernatant or concentrated supernatant in the presence of optional step (a) to provide a conductivity of 2 to 30 mS to form a calcium phytate precipitate, (i) to supernatant from the precipitation of canola protein micellar mass in the absence of optional step (a) to provide a conductivity of 5 to 30 mS to form a calcium phytate precipitate, or (ii) to the partially concentrated supernatant or concentrated supernatant in the presence of optional step (a) to provide a conductivity of 2 to 30 mS to form a calcium phytate precipitate, (c) adjusting the pH of the solution resulting from step (b) without removal of the calcium phytate precipitate to 2.0 to 4.0 to dissolve the precipitate and form a pH-adjusted clear solution, and (d) in the absence of optional step (a) or in the presence of step (ai), concentrating the pH-adjusted clear solution to a concentration of at least 50 g/L to form a clear concentrated canola protein solution, (e) optionally diafiltering the clear concentrated canola protein solution, (f) optionally effecting a colour removal step on the optionally diafiltrated clear concentrated canola protein solution, and (g) drying the optionally discoloured and optionally diafiltered clear concentrated protein solution.
