Advantages

Nutrition :

• Increased fiber and protein content:
• Protein source > 5% spent grain flour.
• Source of fiber > 4% from spent grain flour.
• Rich in fiber > 23% spent grain flour.
• Reduction of caloric load.
• Improvement of the Nutri-Score: decrease of 7 points from 12% incorporation, change from a Nutri-Score of D to C.

Organoleptic :

• The addition of spent grain flour allows the flavors and colors of the products to be modified gradually depending on the incorporation rate.
• In this example, adding amber spent grain flour helps reduce the amount of sugar thanks to its caramelized flavors .

Economic :

• Spent grain flour has a high water retention capacity, the hydration of the dough must be increased, this allows a reduction in material costs.

In practice

Which flour to choose?

All three flours can be used. Blond spent grain flour will bring a more rustic side thanks to these cereal notes, the amber spent grain flour will be more delicious thanks to its caramelized flavor and brown spent grain flour give a more original rendering with a more pronounced color and roasted/cocoa flavors.

At what percentage of incorporation?

From 4% to get a fiber source claim, 23% to be high in fiber. Up to 30% to keep a soft product.

What changes should be taken into account?

Dough hydration must be increased : at least +10% hydration for 10% of added spent grain flour.

By adding some of the liquids to the spent grain flour before kneading, it will be easier.
