The accessibility of iron and zinc was limited in all ingredients, with only faba bean isolate, pea isolate, faba bean concentrate and texturized pea containing accessible iron. Faba bean isolate was found to have the highest amount of accessible iron (67.4 mg/kg) whereas textured pea showed the lowest amount (0.5 mg/kg). The estimated bioavailability of iron and zinc, based on the calculated molar ratio of phytate, was low for all studied ingredients, with isolates showing the highest overall tendency for available iron and zinc. The amino acid composition data revealed limitations regarding valine and/or isoleucine in all protein concentrates and texturized proteins, soy isolate, and faba bean flour. In contrast, no significant differences were found in overall protein digestibility, suggesting that all tested raw materials, including faba bean, can be considered good protein sources.
