Amino Acid Composition of Protein Hydrolysates of Some Lentils of Common Use

G H KAZI ,T IQBAL ,

The chemical investigations of seeds of Cicer arictinum, Len,. emlenta. Pha,colu, radiatu,. Phareolu, mungo and Cajanu, indicu, have been carried out using T.L.e., paper chromato­graphic and colorimetric methods. Amino acid composition of the acid hydrolyzates of proteins ex­tracted from lentils is reported here. Lysine, methionine and tryptophan have been recognized to play an important role in nutritional effectiveness of various foods. The lentils investigated are an impor­tant source of proteineous foods available to people in Asia, therefore much emphasis was laid down on estimation of the amino acids present in them and in turn evaluating various physico-chemical parameters such as protein score and net dietary protein percentage. The results are consolidated in Table I - IX.
