Studies on lysine enriched plasteins from oilseed proteins.

Lysine-enriched plasteins were prepared from groundnut and sesame proteins using N-epsilon-cbz-lysine methyl ester and also enzymic hydrolysates of casein or soybean protein as a source of lysine peptide. Plasteins obtained with the ester had yields of around 40% for sesame and 70% for groundnut. Lysine content was 11-13% for groundnut and 16-19% for sesame plasteins. Those obtained with lysine peptides as a source of this amino acid had high yields (75-85%) and moderate lysine content (6-6.5% for groundnut and 7-9% for sesame plasteins).
