Abstract:
A hemp protein product, which may be an isolate, produces solutions at low pH values and is useful for the fortification of soft drinks and sports drinks without precipitation of protein. The hemp protein product is obtained by extracting a hemp protein source material with an aqueous calcium salt solution to form an aqueous hemp protein solution, separating the aqueous hemp protein solution from residual hemp protein source, adjusting the pH of the aqueous hemp protein solution to a pH of about 1.5 to about 4.4 to produce an acidified hemp protein solution, which may be dried, following optional concentration and diafiltration, to provide the hemp protein product.

Claim (Index 1):
A method of producing a hemp protein product having a protein content of at least about 60 wt %, preferably at least about 90 wt %, (N\u00d76.25) on a dry weight basis, which comprises:\n (a) extracting a hemp protein source with an aqueous calcium salt solution to cause solubilization of hemp protein from the protein source and to form an aqueous hemp protein solution, (b) at least partially separating the aqueous hemp protein solution from residual hemp protein source, (c) optionally diluting the aqueous hemp protein solution, (d) adjusting the pH of the aqueous hemp protein solution to a pH of about 1.5 to about 4.4 to produce an acidified aqueous hemp protein solution, (e) optionally clarifying the acidified hemp protein solution if it is not already clear, (f) alternatively from steps (b) to (e), optionally diluting and then adjusting the pH of the combined aqueous hemp protein solution and residual hemp protein source to a pH of about 1.5 to about 4.4 then separating the acidified aqueous hemp protein solution from residual hemp protein source, (g) optionally concentrating the aqueous hemp protein solution while maintaining the ionic strength substantially constant by a selective membrane technique, (h) optionally diafiltering the optionally concentrated hemp protein solution, and (i) optionally drying the optionally concentrated and optionally diafiltered hemp protein solution.
