Home-made soybean pastes used by farm families show occasionally the presence of tyramine but seldom in commercial "Miso".<BR>From the viewpoint of utilization of soybean as protein sources of farm families, an improvement of the quality of soybean pastes is an important problem in extension services.<BR>In order to disclose the actual condition of the tyramine content distribution of home made soybean pastes 147 samples were collected from 147 farm households in Saitama, Tochigi and Gumma prefectures.<BR>According to the assay results by paper-chromatographical and photometrical procedures, the range of tyramine content in these soybean pastes was from 0 to 53mg%. And among these soybean pastes the group that contains more than 30mg% tyramine accounted for 10% of the total.<BR>However, the correlation between tyramine content and other individual factors such as duration of aging, sodium chloride content and ratio of materials could not be found.
