title: Amino acids profile and antioxidant activity of differentLupinus angustifoliusseeds after solid state and submerged fermentations.
abstract: The objective of this study was to investigate the amino acids profile, total phenolic compounds (TPC) content, antioxidant activity after submerged (SmF) and solid state (SSF) fermentations of differentLupinus angustifoliusseeds by theLactobacillus sakeiKTU05-6. Additionally, the impact of different lupin seeds as fermentation media for LAB biomass and d/l-lactic acid production was analysed. The d/l ratio for SmF and SSF treated lupin samples varied from 0.15 to 0.45 and from 0.12 to 0.46, 16 respectively. Nutritional analysis highlighted a substantial increase in the TPC content and antioxidant activity up to 31.5-48.8% for SSF treatedL. angustifoliussamples compared to unfermented. The interaction between analysed factors (lupin variety and fermentation conditions) had a significant influence on essential and nonessential amino acids profile.
