Texgran is a source of protein that is produced from soybean protein. It can be cooked taking the place of meat. It is inexpensive, and is cooked highly effectively. However, through the investgation of its essential amino acids construction it has been found that the sulfur-containing amino acids are limited and protein score of texgran is 58; accordingly its nutritive value of protein is inferior to the animal protein. In order to use it effectively in our diet as a substitute for animal foods, these limiting amino acids should be supplemented. On the other hand, effective use of texgran will improve Japanese diet from the viewpoint of protein nutrition because it contains more lysine than cereals do and more tryptophan than fish and shellfish do. Actually it is advisable to use texgran as a principal source of protein and supplement a small amount of animal foods with high methionine content. Particularly it is practical to include texgran and eggs together in a menu to raise the protein score of the diet.
