Fe absorption was measured in adult human subjects consuming different cereal foods fortified with radiolabelled FeSO4, ferrous fumarate or NaFeEDTA, or with radiolabelled FeSO4 or ferric pyrophosphate in combination with different concentrations of Na2EDTA. Mean Fe absorption from wheat, wheat–soyabean and quinoa (Chenopodium quinoa) infant cereals fortified with FeSO4 or ferrous fumarate ranged from 0·6 to 2·2 %. For each infant cereal, mean Fe absorption from ferrous fumarate was similar to that from FeSO4 (absorption ratio 0·91–1·28). Mean Fe absorption from FeSO4-fortified bread rolls was 1·0 ...

A simplification of the pilot-plant scale modified Nagano method yielding two protein fractions, glycinin and â-conglycinin, by pH adjustment and ultrafiltration membrane separation was developed and compared with our pilot-plant-scale modified Nagano procedure and with a soy protein isolate pilot-plant procedure as our reference process. Two protein fractions, glycinin and â-conglycinin, were produced from our simplified process and compared to the three protein fractions, glycinin, â-conglycinin, and an intermediate protein mixture, produced with the modified Nagano method. The pilot-plant yields of glycinin, â-conglycinin, and intermediate mixture fractions from the modified Nagano method were 9.4, 10.3, and 4.8 ...
