Sponge Cake: The Science of Lightness

The Sponge Cake: The Science of Lightness

Sponge cakemay look simple, but achieving perfect lightness and volume requires delicate balance. In industrial baking, this product’s quality depends on precise control - from ingredient selection to mixing, and baking. A great sponge cake must combine height, springiness, softness, and a fine crumb-without collapsing or drying out.

Delivering that signature texture and golden surface relies on flour characteristics that promote stability, and uniform expansion during baking.

At the Table – Discover the “Sponge Cake” Video

In the Back to Flour Series, the At the Table video dedicated to sponge cake explores the characteristics that define quality:

• Volume & Rise – airy developmentwithout collapse.
• Softness & Springiness – alight, elastic crumb that bounces back.
• Crumb Texture – smooth and uniform,free of large holes.
• Moisture & Staling – enoughinner moisture to keep softness, but not too much to compromise structure.
• Color - a uniform golden surfacethat signals proper baking and ingredient balance.

These attributes are directly shaped by flour composition:

These attributes are directly influenced by flour composition. roteins and starches provide the structure that supports volume and crumb uniformity. Damaged starch increases water absorption and affects texture balance. Amylase activity regulates sugar availability, impacting color and softness. Ash content influences crumb precision and color tone, while lipids improve emulsion stability and delay staling.
