| Abstract: | The content of dry matter, total nitrogen, and amino acids (except for tryptophan) in fresh and canned broad bean (Vica fabav. major) seedswas determined, in the canned product whole seeds or cotyledons without hull being analysed. Two Dutch bred cultivars, Comprimo RS with large seeds and medium sized Threefoldwhite, were investigated at four stages of maturity defined by the content of dry matter at levels of about 25% (stage I), 30% (II), 35% (III), and 40% (IV). Amino acid content in 100 g fresh weight was similar in the two cultivars, rapidly increasing with maturation. The value of protein expressed by the EAA index was almost the same for the investigated cvs, usually being slightly higher in the case of more mature seeds. Whole seeds from canned product contained slightly less amino acids than the raw material while the EAA index showed similar or slightly lower values for whole seeds than for the raw vegetable. The content of all the amino acids (except for tyrosine) was greater and the EAA indices were higher in the cotyledons of canned broad bean than in whole seeds. Methionine with cystine were the limiting amino acids in fresh and canned seeds. |
