Impact of germination time and type of illumination on the antioxidant compounds and antioxidant capacity of Lens culinaris sprouts

Lentil sprouts have the potential to be an effective dietary source of polyphenolics. The effects of different illumination conditions of germination on the content of polyphenolics and antioxidant capacities of lentils sprouts have been studied. Obtained results indicated that both germination and illumination conditions modified the polyphenolic profiles and biological activity. Studies have shown that phenolic phytochemicals can be stimulated by cultivation under continuous light; a significant increase in p-hydroxybenzoic, benzoic, caffeic acids content on days 3 and 4 after germination was observed. Antioxidant activity of sprouts was correlated with phenolics content and closely depended on the cultivation conditions. To achieve lentil sprouts with enhanced nutraceutical value (antioxidant potential), germination in the presence of continuous light can be suggested.

► Lentil sprouts contain phenolics and demonstrate a wide range of antioxidant activities.
► Antioxidant activities are strongly, positively correlated with phenolics content.
► Germination conditions influence the phenolics level and antioxidant potential.
► Antioxidant power is positively correlated with light condition during germination.
► Antioxidant potential is evaluated most effectively by continuous illumination.
