Abstract
The qualities of home-made soybean paste used by farm families were investigated from viewpoint of their essential amino acid composition.
Ten essential amino acids in 28 soybean paste samples, which were collected from farm households in Saitama, Tochigi and Gumma Prefectures, were analysed by microbiological assay method.
Results were as follows: leucine 7.7, isoleucine 4.7, lysine 5.7, methionine 1.2, cystine 1.3, phenylalanine 4.7, threonine 3.4, tryptophan 0.9, tyrosine 3.9 and valine 4.6g per cent in protein.
The difference of essential amino acid composition among any kinds of home-made soybean pastes could not be found.
