Evaluation of protein composition and functionality of lupin protein isolates extracted from different blue lupin (<i>Lupinus angustifolius)</i> cultivars.

ABSTRACT: Lupin is a promising alternative protein source due to the climate resilience of this crop and its large protein content. Protein isolates (PIs) were obtained after alkaline extraction-isoelectric precipitation from 22 narrow-leaf lupin genotypes from commercial and experimental breeding lines cultivated under controlled environmental conditions. The isolates were screened for their protein content and ratio of the main proteins, namely α-conglutin (legumin-like) and β-conglutin (vicilin-like). The molecular mass of the proteins ranged from 320 to 400 kDa and 180-260 kDa for α- and β-conglutins, respectively. In all genotypes, the ratio of α-conglutin to the total (sum of α-conglutin + β-conglutin) exceeded 53 %. Six varieties were selected for further compositional and functional analysis
