The Chopin Alveograph test assesses gluten strength by inflating a piece of dough until it ruptures. Dough is prepared, developed, shaped into disks, and allowed to rest. Each disk is then inflated with air, and the resistance to expansion is recorded. The resulting curve provides insights into dough elasticity and extensibility, which reflect gluten quality and dough strength. Since dough is prepared with a consistent 50% hydration level, flours with lower water absorption (WA) capacity produce more viscous dough, making the Alveograph a useful tool for measuring WA. During dough fermentation, gas cells expand in three dimensions, similar to the Alveograph's measurement of dough sheet expansion. This test offers valuable predictions about dough behavior and baking quality for various applications, such as bread and confectionery. Flour millers and manufacturers use Alveograph results to specify flour characteristics, ensuring a consistent production process and product quality, including the balance between dough deformation resistance and extensibility. Related terms include alpha-amylase, quality control, dough development, malting, endosperm, grinding, wheat flour, bread dough, dough quality, and gluten.
