US 2026/0283175 A1 · IMPROVED PREPARATION OF SUNFLOWER PROTEIN PRODUCTS ("SF871NDS")

Abstract

Processes for preparing sunflower protein products from a sunflower protein source are provided. Protein extracted from the sunflower protein source is processed to provide a sunflower protein product having a protein content of greater than 60 wt % (N×6.25) d.b. A separation step is employed in the process to improve the efficiency of membrane processing. Additional sunflower protein product is prepared from the residual sunflower protein source after protein extraction, preferably having a protein content of greater than 30 wt % (N×6.25) d.b. These protein products are also provided as are food and beverages, pet food, animal feed, industrial product, cosmetic product or personal care product comprising the sunflower protein products.

A process for preparing a sunflower protein product from a sunflower protein source, the sunflower protein product having a protein content of greater than 60 wt % (N×6.25) d.b., the process comprising

a) extracting sunflower protein from a sunflower protein source, optionally by a counter-current procedure, to cause solubilization of the sunflower protein from the sunflower protein source to produce an aqueous phase and a residual sunflower protein source;
wherein optionally an anti-foamer, which is optionally a food-grade, non-silicone based anti-foamer, is added during the extraction to reduce the volume of foam formed upon further processing;
b) separating the aqueous phase from the residual sunflower protein source to produce an aqueous sunflower protein solution and a separated residual sunflower protein source, wherein optionally the aqueous sunflower protein solution is treated with an adsorbent, which is optionally granulated activated carbon, to remove colour and/or odour compounds
c) optionally defatting the separated aqueous sunflower protein solution to at least partially remove fat from the separated aqueous sunflower protein solution;
d) adjusting the pH of the aqueous sunflower protein solution to an acidic value in the range of about pH 1.5 to about pH 5.0 to provide an acidified sunflower protein solution;
e) optionally concentrating the acidified sunflower protein solution;
f) optionally diafiltering the concentrated acidified sunflower protein solution using water as the diafiltration solution or optionally diafiltering the acidified sunflower protein solution using water prior to concentration or optionally diafiltering the partially concentrated acidified sunflower protein solution using water;
g) optionally drying the acidified sunflower protein solution (d) or optionally concentrated and/or diafiltered sunflower protein solution ((e) or (f)) to provide a sunflower protein product;
wherein steps e) and f) may optionally be carried out simultaneously.
