About these values

The record is firm tofu made with calcium sulfate and nigari. Tofu varies by firmness, so a package label may differ. The USDA record is "Tofu, firm, prepared with calcium sulfate and magnesium chloride (nigari)" (SR Legacy, FDC ID 172448). It gives 9.04 g of protein and 78 kcal per 100 g.

Protein in a portion is its weight times the protein per 100 g, divided by 100. For half a cup of tofu: 126 × 9.04 ÷ 100 = 11.4 g. Values on this page are rounded to 0.1 g.

A packaged food's own label can differ from the USDA average. When you have the label, its numbers are the ones for that product.
