The consumer in the United States tends to think that flour refers to all-purpose white flour or, possibly, whole wheat or cake flour. Unfortunately, baked recipes are generally assumed to use all-purpose flour. Increasingly, other sources are being used for their cost, nutritive value, specialized functional properties, unique sensory characteristics or simply due to marketability. The many different sources may be grains, oilseeds, and legumes. The oilseeds [soybean, flax, safflower, peanut, rapeseed, coconut, cottonseed, sesame, and others] and legume flours [navy bean, lupine, lima bean, chickpea, cowpea, fababean, pigeon pea, lentil] are increasingly being used as substitutes or supplements for wheat flour.
Each of these alternate sources have their advantage and disadvantage. The phenolics are a particular problem, especially for the legumes, rapeseed and mustard. They are intermediate in concentration in soybean, flax, peanut, and safflower flour and low in coconut, cottonseed and sesame flour. Other problems constantly are being identified and minimized, such as the gossypol in cottonseed.
