Zhong et al. (2018) reviewed biochemical and physicochemical functionalities of seed coats of five globally important pulses: chickpea, field pea, broad/faba bean, lentil, and mung bean. It was reported that high levels of dietary fiber, minerals, and potential health‐promoting phytochemicals in the seed coats indicate their great potential to be used as a natural, nutritious dietary fiber.

The cotyledon comprises the greatest portion of the bean in terms of both weight and volume and contributes a valuable component to the texture and nutritive value of the bean as food. The cotyledon portion, which is responsible for the embryonic leaf tissue during germination, makes up 90.5% of the total bean on a dry‐weight basis. Dry cotyledons have been reported to contain 39.3% starch, 27.5% protein, 1.65% lipids, and 3.5% ash (Powrie et al. 1960). Botanically, the cotyledons of dry beans are a segment of the embryo and are thus differentiated from the endosperm of common cereal grains. As the seed matures, these stored energy reserves increase and upon germination are mobilized and utilized for initial seedling growth.
