Description
Cooling pastry dough is a critical thermal step that controls fat crystallization, gluten relaxation, and starch retrogradation to achieve desired flakiness, tenderness, and shelf‑life.
Technical
During cooling, butter fat crystallizes into 20–30 % fat crystals, while gluten polymerization is limited and starch retrogrades, especially around 4 °C. These processes reduce water activity, slow enzymatic activity, and stabilize the crumb structure, thereby extending shelf‑life and preventing spoilage.
