How to Calculate Flour Blend Protein

Formula

Blend Protein % = (Bread Flour g x 0.127 + AP Flour g x 0.105) / Total Flour g x 100

Protein Levels by Flour Type

Cake flour: 7-8%

Pastry flour: 8-9%

All-purpose flour: 10-12%

Bread flour: 12-13%

High-gluten flour: 13-14%

Why Protein Matters

Higher protein creates more gluten, which provides structure and chew. Pizza and bagels need 12-14%, while cakes need 7-9% for tenderness.

计算示例

Blend 300 g bread flour with 200 g all-purpose flour.

01Bread flour protein: 300 x 0.127 = 38.1 g.
02AP flour protein: 200 x 0.105 = 21.0 g.
03Total protein: 38.1 + 21.0 = 59.1 g.
04Total flour: 300 + 200 = 500 g.
05Blend protein = 59.1 / 500 x 100 = 11.8%.

常见问题

What protein level do I need for pizza dough?

Traditional Neapolitan pizza uses 12-13% protein flour (tipo 00 or bread flour). New York style works well with 12-14%. Lower protein gives a more tender, less chewy crust.

Can I use vital wheat gluten to increase protein?

Yes. Adding 1 tablespoon (9 g) of vital wheat gluten per cup of all-purpose flour raises the protein by about 1.5 percentage points.

Does protein content affect hydration?

Yes. Higher protein flour absorbs more water. Increase hydration by 1-2% for each additional percentage point of protein.
