Malt powder от John Spottiswood

You can make malt powder by allowing whole grains to sprout briefly, drying them, and then grinding them into a powder. Commercial malt powders are usually made with barley, and they're used extensively by commercial bakers. There are two main types of malt powder: diastatic and non-diastatic. Diastatic malt contains active enzymes which help break starch down into sugar. The extra sugar feeds the yeast in the dough, helping the bread to rise, and also gives the bread a browner crust. It's often used to make crusty breads. Non-diastatic malt doesn't have active enzymes, but it gives baked goods better flavor and a shinier, browner crust. It's used in everything from bagels to croissants to breakfast cereals. Don't confuse malt powder with malted milk powder, which also contains powdered milk and wheat flour and is used to make beverages. Look for malt powder in health food stores or baking supply stores.
