Abstract
Recent trends in healthy lifestyle and diet made functional foods rich in
quality nutrients and bioactive compounds with potential health benefits highly sought
after. Some cultivated plants, such as soya and chia can provide a viable source of
nutraceuticals with high fibre, protein, and protective antioxidant potential. The wholegrain flours of black soya beans and black chia seeds were used in this study. Potential
nutritive and health-benefitting properties of these flours were compared by assessing
their chemical composition and antioxidant profile. The content of dietary fibres such
as NDF, ADF, ADL and hemicellulose determined in black chia seed sample was
higher than in black soya soya beans which had higher fibre content. The total protein
content recorded in black soya beans was almost as twice as high (42.26+0.14%) as
chia protein content (25.04+0,20%). Black soya beans had the highest content of water
soluble proteins (29.00+0.13% d.m.) with NSI (nitrogen solubility index) acounting
for as much as 70.96+0.31% of total proteins, while black chia seeds had the highest
content of globulins (14.64+0.07% d.m.) and NSI 58.48+0.27% of total proteins. Both
black soya bean and black chia contained a high amount of total phenolic compounds
(830,66+5.46 and 1201.94+16.29 mg GAE/kg, respectively) and exhibited a
considerable total antioxidant capacity, which makes them good contestants for
functional food ingredients with potential health benefits
