The Biscuit: Dry, Crispy, and Structurally Controlled

Biscuit quality depends on achieving the right balance between crispness, crumbliness, structure, and stability over time. Whether smooth or rough, thin or thicker, biscuits must deliver a dry, pleasant bite while maintaining their integrity throughout shelf life.

A great biscuit combines color, size and shape, volume, crispness, flakiness, texture, crumbling, moisture control, and resistance to staling and sogginess. Size, shape, and height must be tightly controlled to ensure biscuits fit properly into packaging, maintain consistent count, and meet consumer expectations. Biscuits must also remain dry over time, which is why they are often individually packed to protect them from moisture.

Because biscuits are low-moisture products, controlling how water is managed during mixing and baking is essential, and this starts with flour.

At the Table – Discover the “Biscuit” Video

In the Back to Flour Series, the At the Table video dedicated to biscuits highlights that flour plays a decisive role in defining both product structure and processing behavior.

Protein content must remain relatively low to avoid forming a strong gluten network. Excess protein would increase water absorption and lead to harder biscuits with less desirable texture. Damaged starch must also be controlled at low levels. Because it binds large amounts of water, too much damaged starch requires higher water addition during mixing, water that must later be removed during baking, increasing the risk of cracks and product breakage.

Starch gelatinization plays a central role in defining biscuit texture. It directly influences crumbliness, flakiness, and internal structure. Depending on the product type, biscuits may exhibit layered structures or more aerated internal structures with bubbles, and gelatinization helps stabilize these differences during baking.

Lipids, often present in significant amounts in biscuit formulations, contribute to texture and mouthfeel, while also influencing shelf life. However, they can lead to rancidity over time if storage conditions are not well controlled.

Enzymatic activity (amylases) and sugar both impact color development during baking. Higher activity or sugar content leads to increased browning, requiring careful control to achieve the desired golden color. Ash content also affects color, with higher levels producing greyer biscuits, except in specific products such as oatmeal biscuits.

Finally, starch retrogradation can influence texture over time by making biscuits harder, although its impact is generally more limited than in softer bakery products.

Together, these flour components determine how the dough behaves during processing and how the biscuit ultimately looks, breaks, and feels when eaten.

What’s Next?

This focus on Biscuits is part of the Back to Flour Series, which connects flour functionality to finished product quality across all bakery segments. By understanding how flour composition controls water management, structure, and texture, manufacturers can consistently deliver biscuits with the desired crispness, appearance, and shelf-life stability.

The Back to Flour Series is constantly growing; with videos, technical PDFs, and resources across At the Table, Transformation of Dough, Secrets of Flour, and more technical insights to come.
