Does whole wheat flour absorb more water?

The reason for this is that, as explained above, gluten will absorb water, which is why flours higher in gluten-forming proteins generally absorb more water.

What’s the difference between whole wheat and white flour?

But using whole wheat takes things up a notch. Unlike white flour, whole wheat–like other unrefined grains–contains germ and bran. These two components bear minerals like zinc, magnesium and iron, as well as omega-3 fatty acids and dietary fiber.

What happens when water is added to flour?

When water is added to the flour and it is mixed, there is competition between the different compounds to absorb the liquid. Damaged starch is the winner in this game (it’s said to be very hygroscopic) and attracts water more quickly than protein. But damaged starch doesn’t know how to retain the water and the water in turn is also released.

What is flour absorption and why does it matter?

When you are working with wheat flour, you’d be wise to become familiar with the concept of flour absorption. The absorbency of flour varies from grain to grain and from season to season. The same brand of wheat flour may absorb more or less water depending on the moisture in your kitchen or where the flour was stored.
