Phenolic content and antioxidant potential of lentil sprouts may be enhanced by treatment of seedlings in abiotic stress conditions without any negative influence on nutritional quality.
The health-relevant and nutritional quality of sprouts was improved by elicitation of 2-day-old sprouts with oxidative, osmotic, ion-osmotic and temperature stresses.
Among the sprouts studied, those obtained by elicitation with osmotic (600 mM mannitol) and ion-osmotic (300 mM NaCl) shocks had the highest total phenolic content levels: 6.52 and 6.56 mg/g flour, respectively.
Oxidative stress significantly enhanced the levels of (+)-catechin and p-coumaric acid.
A marked elevation of the chlorogenic and gallic acid contents was also determined for sprouts induced at 4 C and 40 C.
The elevated phenolic content was translated into the antioxidant potential of sprouts, especially the ability to reduce lipid oxidation.
A marked elevation of this ability was determined for seedlings treated with 20 mM, 200 mM H2O2 (oxidative stress) and 600 mM mannitol (osmotic stress); about a 12-fold, 8-fold and 9.5-fold increase in respect to control sprouts.
The highest ability to quench free radicals was observed in sprouts induced by osmotic stress (IC50- 4.91 and 5.12 mg/ ml for 200 mM and 600 mM mannitol, respectively).
The highest total antioxidant activity indexes were determined for sprouts elicited with 20 mM H2O2 and 600 mM mannitol: 4.0 and 3.4, respectively.
All studied growth conditions, except induction at 40 C, caused a significant elevation of resistant starch levels which was also affected in a subsequent reduction of starch digestibility.
Improvement of sprout quality by elicitation with abiotic stresses is a cheap and easy biotechnology and it seems to be an alternative to conventional techniques applied to improve the health promoting phytochemical levels and bioactivity of low-processed food.
