Bread Flour Protein Rechner — Formel

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.

    Lösungsbeispiel

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

    1. Bread flour protein: 300 x 0.127 = 38.1 g.
    2. AP flour protein: 200 x 0.105 = 21.0 g.
    3. Total protein: 38.1 + 21.0 = 59.1 g.
    4. Total flour: 300 + 200 = 500 g.
    5. Blend protein = 59.1 / 500 x 100 = 11.8%.
