Abstract
Provided herein are processes for producing a sunflower seed protein isolate (SFPI) from de-oiled sunflower seed flour that is economical and produces oil seed protein isolate that has unique composition and functionality. The process involves use of low temperatures, below where denaturation of proteins occurs, to produce a sunflower seed protein product with a protein content 80-98 wt % (N×6.25) on a dry basis and ≤3% oil while substantially maintaining the native form of the proteins in the flour.
Claims31
A sunflower seed protein isolate extraction process comprising, step-wise:
- a. alkaline hydration of hull-free, desolvented, de-oiled sunflower seed flour with an aqueous solution:
- i) at a pH of 7.5-10,
- ii) at a temperature of 18-60° C.,
- iii) including Na and/or Ca and/or Mg salt,
- b. separation of solids from the solution, producing a liquid fraction,
- c. precipitation and separation of protein from liquid fraction:
- i) at pH 4-6,
- ii) at a temperature of 18-60° C.,
- d. dilution of the protein to produce a slurry,
- e. homogenization and sterilization of protein slurry
- f. drying protein slurry.
