How to Prepare Soy Flour
Soy flour is a wholesome, nutrient-rich ingredient that is used to make meat alternatives, dairy alternatives and baked goods. Since it is a natural source of protein, dietary fiber and isoflavones, soy flour can greatly enrich any food it is added to. Although it cannot fully replace wheat flour in recipes, there are many advantages to baking with soy flour. When combined with regular wheat flour, soy flour can extend the shelf life of baked goods, enhance their texture and boost their protein content. It can also be used in fried foods to reduce the absorption of fat.
Soy flour commonly retails in natural food stores, but it can also be prepared at home with mature soybeans. There are two standard practices for milling soybeans, the wet heat and dry heat methods. Both are simple techniques that use a conventional kitchen oven. While the wet heat method involves blanching and slow-roasting the soybeans, the dry heat method entails soaking and quick-baking the soybeans.

Tips & Warnings
Soy flour can be stored in an airtight container for up to one year. To avoid clumping, stir or whisk before measuring.
Soy flour can produce a range of tastes depending on how it is processed. If you desire a more "nutty" flavor, consider lightly toasting your soy flour in a saucepan before using.
Since any dough with soy flour has a tendency to brown faster, the baking process should always be closely monitored.
Although soy flour is a protein-rich ingredient, it lacks gluten -- the specific protein that gives baked goods their structure. As a result, it is not recommended to substitute more than 25% of grain flours with soy flour. Nonetheless, even modest ratios of soy flour to wheat flour can dramatically increase the protein content of baked goods. For instance, a yeast-raised bread with 12% soy flour and 88% wheat flour has a 40% higher protein content than pure wheat bread. (See Reference 2)
