The Anatomy of a Perfect Biscuit

Biscuit quality is defined by a combination of essential characteristics that shape both appearance and texture. Color, size and shape, volume and rise, crispness, flakiness, texture, crumbling, moisture, staling, and sogginess all contribute to how a biscuit is perceived and performs. The balance between these attributes determines the overall quality and consistency of the final product.

Flour composition plays a key role in achieving this balance. Protein quantity and quality and damaged starch show the strongest contribution, while starch gelatinisation and lipids have a significant influence. Amylase activity contributes at an average level, while ash content and sugars brought by the flour play a smaller role. Starch retrogradation has a more limited impact. The generally observed levels of each component are also indicated for biscuit applications.

By highlighting the relative contribution of these flour components, this resource helps clarify how flour composition supports consistent biscuit quality.
