Bambara groundnuts, also known in Thai as
“Thua Rang”, are non-traditional seeds, but are
now cultivated as a promising crop in the southern
part of Thailand to contribute as a locally cultivated
produce. An important attribute of the Bambara
groundnuts is their tolerance to drought and poor
soil, being very adaptable to hot temperatures, but
also tolerant to rainfall, while having relatively
good resistance to pests and diseases (Collision et
al., 2000). The Bambara groundnut seeds are rich in
proteins with about 18 to 24% content, and have a
good balance of essential amino acids with relatively
high proportions of lysine and methionine (Eltayeb
et al., 2011). Elegbede (1998) and Stephens (2003)
noted that Bambara groundnut protein contains higher
amounts of the essential amino acid methionine than
other grain legumes. For this reason, the protein
isolates from Bambara groundnut could be used to
complement other grain proteins in order to provide a
blanched amino acid profile.
