n Egypt, mung bean (Phaseoius aureus) has been introduced recently by the Ministry of Agriculture. Mung bean is an excellent source of protein (27%), and its essential amino acid composition compares favourably with that of soybean, kidney bean and FAO/WHO reference protein (El-Adawy, 1996; Fan & Sosulski, 1974; Thompson, Hung, Wang, Rapser, & Gade, 1976). However, antinutritional factors limit the food applications of mung bean. Therefore, dehulling of the seeds before milling has been used to overcome this problem (El-Adawy, 1996; Thompson et al., 1976).
