Conclusions
Consumption of natural and healthy foods is nowadays a major
interest of consumers. Soybean products are very important
foods due to their numerous nutritional benefits and their global
availability. This study presented soy whey fermented with L.
plantarum B1–6, which provides a potential biotechnological
process without causing serious environmental pollution. L.
plantarum B1–6 had good growth in soy whey and could provide
probiotic property for the host and had the capacity to improve
nutritional and functional properties of the products. Thus, the
enhancement of the antioxidant activity of soy whey by fermentation
with L. plantarum B1–6 and the ability to protect DNA
oxidation which was demonstrated is of significance. This is
the first report which evaluates the DNA protective ability of
fermented soy whey. Therefore, we propose the strain of L.
plantarum B1–6 as starter culture to obtain a functional soy beverage
rich in phenolics and isoflavone aglycones with enhanced
health-promoting properties. Furthermore, use of fermented
soy whey as nutraceutical and functional food ingredient or
inclusion in therapeutic diet for patients with diseases linked
to oxidative stress may be recommended.
