The compositions of total and free amino acids in parts of Omija were investigated.
The most abundant amino acids in fruits, endocarps, and seeds were arginine (50.80%), lysine (14.37%), glutamic acid (14.22%), respectively.
Since the amino acid scores of fruits, endocarps, and seeds were 9.4, 11.9, and 16.7, respectively, the limiting amino acid of each part were S-compound amino acids. In the composition of free amino acids, contents of lysine were highest one such as 51.78, 57.00 and 32.88% in fruits, endocarps and seeds, respectively. The contents of histidine from free amino acids were 23.62% in fruits, 22.37% in endocarps, and 26.41% in seeds.
