In practice

Which flour to choose?

We chose amber spent grain flour in this application to be able to reduce the amount of sugar added to the recipe.

The blond spent grain flour will bring cereal flavors which will give the biscuits a more rustic side.

Brown spent grain flour will bring a darker color as well as roasted or even cocoa notes.

At what percentage of incorporation?

From 5% to start having a color change.

Around 20-40% to have interesting modifications of the aromatic profile as well as nutritional values.

What changes should be taken into account?

Since spent grain flour is low in gluten and high in fibre, the egg and/or fat content of the biscuits must be slightly increased compared to a 100% wheat flour recipe.

The incorporation of spent grain flour also helps to reduce the shrinkage of the dough during rolling.
