Claim 0:
1. A method for obtaining a refined protein component from a non-animal natural and/or modified non-animal natural source comprising the steps of:
a) obtaining a protein preparation from the non-animal natural or modified non-animal natural source;
b) washing the protein preparation at a wash pH;
c) aqueously extracting the protein preparation at an extraction pH to obtain an aqueous protein solution;
d) separating the aqueous protein solution from non-aqueous components;
e) heating the aqueous protein solution to a temperature of about 60° C.;
f) adding a calcium salt suitable for coagulating protein and adjusting the aqueous protein solution to a precipitation pH between about 6 and about 3 to precipitate protein and obtain a protein precipitate;
g) separating the protein precipitate from non-precipitated components; and
h) washing the protein precipitate to obtain the refined protein component;
wherein step (f) is the only protein precipitation step in the method.
