Abstract
Maize is one of the world’s mostly cultivated crops which are consumed by the humans. The quality of maize protein is a vital factor in combating human malnutrition, a problem that is rapidly increasing among children. This study focuses on enhancing maize's protein quality by increasing lysine and tryptophan concentrations while reducing zein content. Seventeen in-house maize lines were analyzed for key biochemical characteristics. Among these, the CML161 line stood out, with a total protein content of 11.831%. The tryptophan and lysine contents in CML161 were 0.68% and 3.3%, respectively. Additionally, the total starch content in CML161 was found to be 37.8%. The endosperm modification test showed 100% opaqueness in the CML161 variety. Based on these findings, it can be concluded that CML161 contains a quality protein content of 5.74%, making it a promising candidate for further studies aimed at addressing malnutrition.
