Footnotes:
1  Descriptive terms (soft, firm, extra firm) vary in usage between manufacturers as there are no standards for the various types of tofu.
2  Manufacturers use either magnesium chloride (nigari), calcium sulfate, or both in varying quantities to precipitate the protein. Calcium and magnesium contents will vary accordingly.
