Abstract
A canola protein isolate having a protein content of at least about 90 wt % (N×6.25) is employed as an at least partial replacement for at least one component providing functionality in a food composition. The canola protein isolate is a blend of canola protein isolate in the form of an amorphous protein mass formed by settling the solid phase of a dispersion of protein micelles and mixing the amorphous mass with concentrated supernatant from the setting step and drying the mixture.
Claims5
In a food composition comprising a foodstuff and at least one component providing functionality in said food composition, the improvement which comprises at least partially replacing said at least one component by a substantially undenatured canola protein isolate having a protein content of at least about 90 wt %, as determined by Kjeldahl nitrogen×6.25 on a dry weight basis, said canola protein isolate comprising a blend of:
- (1) a first canola protein isolate having a protein content of at least 90 wt % on a dry weight base and at a Kjeldahl nitrogen conversion of N×6.25 and which exhibits a protein profile which is:
- about 60 to about 98 wt % of 7S protein
- about 1 to about 15 wt % of 12S protein
- 0 to about 25 wt % of 2S protein, and
- (2) a second canola protein isolate having a protein content of at least about 90 wt % on a dry weight basis and a Kjeldahl conversion of N×6.25 and which exhibits a protein profile which is:
- about 60 to about 95 wt % of 2S protein
- about 5 to about 40 wt % of 7S protein
- 0 to about 5 wt % of 12S protein
In a food composition comprising a foodstuff and at least one component providing functionality in said food composition, the improvement which comprises at least partially replacing said at least one component by a substantially undenatured canola protein isolate having a protein content of at least about 90 wt % as determined by Kjeldahl nitrogen×6.25 on a dry weight basis, said canola protein isolate being a blend of an amorphous protein mass formed by settling the solid phase from an aqueous dispersion of canola protein miscelles and mixing said amorphous protein mass with concentrated supernatant from the settling step.
