Lupin is one of the most nutritionally interesting legumes as an excellent source of protein, minerals and fibre. In this study, a narrow-leaved lupin (Lupinus albus L.) flour and a white lupin (Lupinus angustifolius L.) protein concentrate were analysed in purity and in mixtures obtained by partial substitution of durum wheat re-milled semolina. The mineral profile (micro- and macronutrients), protein content and heavy metals were determined. The addition of white lupin flour (FL) and narrow-leaved lupin protein concentrate (CPL) to the semolina increased the protein content, except for the 3% FL sample. The pure FL had a very high protein content (40.05 g/100 g), which increased to 55.00 g/100 g in CPL. Flour blends had higher levels of micronutrients than the re-milled semolina (SR), which increased with the degree of substitution. Regarding macronutrients, CPL, FL and their blends showed higher values than SR, especially K and P. The high micronutrient and protein contents make CPL and FL, in combination with re-milled semolina, potentially suitable for biofortified and functional food formulations.
