Back to Flour The Anatomy of a Perfect Steamed Bun

Steamed buns are characterized by a unique combination of softness, springiness, and a smooth, uniform surface. Their quality relies on achieving the right balance between volume, crumb texture, and moisture, while maintaining a stable structure over time. Color, size and shape, and resistance to staling also contribute to defining how the product is perceived and evaluated.

The document highlights how flour composition supports these characteristics. Protein quantity and quality, amylase activity, and damaged starch are identified as the main contributing components. Starch gelatinisation also plays an important role, while ash content has a significant influence. Lipids and starch retrogradation contribute to a lesser extent. The generally observed levels of these components are indicated for steamed bun applications.

By focusing on these contributions, this resource provides a clear overview of how flour composition supports the specific texture and structure expected in steamed buns.
