Abstract
Provided herein are processes for producing a canola seed protein isolate (CPI) from de-oiled canola flour that is economical and produces canola protein isolate that has unique composition and functionality. The process involves use of low temperatures below where denaturation of proteins occurs to produce a canola protein product with a protein content 80-98 wt % (N×6.25) on a dry basis while substantially maintaining the native form of the proteins in the flour.
Claims63
A canola protein isolate extraction process comprising, step-wise:
- a. separating hulls from desolvented, de-oiled canola flour,
- b. alkaline hydration of hull-free, desolvented, de-oiled canola flour with an aqueous solution:
- i) at a pH of 7-11,
- ii) at a temperature of 5-62° C.,
- iii) optionally including Na and/or Ca and/or Mg salt,
- c. separation of solids from the solution, producing a liquid fraction,
- d. precipitation and separation of protein from liquid fraction:
- i) at pH 3-7.5
- ii) at a temperature of 5-62° C.,
- e. dilution of the protein to produce a slurry,
- f. homogenization and sterilization of protein slurry
- g. drying protein slurry.
A canola seed protein isolate comprising oleosin.
