Cowpea a member of the legume family was sprouted to be able to improve its nutritive value especially the amino acids. Lysine, however, is highly venerable to process loss. One of the ways to determine the availability of the essential amino acids is to determine the available lysine. This study was geared not only in measuring the available amino acids, by determining the available lysine using the FDNB (Fluoro-di-nitro-benzene) extraction method, but to improve on the availability of these amino acids through germination. This method is also capable of removing the drudgery of animal study and faster to achieve the desired results.
