Abstract

This study evaluates the optimal conditions for elicitation with H2O2 for improving the antioxidant capacity of lentil sprouts. Generally, except for 3-day-old sprouts, elicitation increased phenolic content (in respect to the control). The highest phenolic content was determined for 2-day-old sprouts treated with 15 mM H2O2 (0.71 mg/gf.m.). All the studied modifications increased the antioxidant potential of sprouts. The highest elevation (3.2-fold) was found for 5-day-old sprouts (single 15 mM H2O2 treatment). A significant increase was also found on the 2nd and 4th days (2.13- and 2.14-fold, respectively). Elicitation induced tyrosine and phenylalanine ammonia-lyases activities. H2O2 treatments induced the activity of catalase - especially for 2-day-old sprouts treated with 150 mM H2O2 (597 U/gf.m.). Elicitation with H2O2 is a useful tool for designing some features of sprouts. Phenolic content and antioxidant capacity are strongly affected by concentration of the elicitor, and time and intervals of its application.
