“…If the results are analysed from the point of view of sulphur supplementation, our observations are different from those of Kestwal et al (2011), who studied the sodium thiosulphate (Na2S2O3) influence in 12-day cruciferous sprouts. They noticed that different concentrations of sulphur supplementation, increased TPC-FC and DPPH…”

“…Such aromatic compounds may exist in much smaller amounts in untreated sprouts or may be formed only in the case of sodium sulphate treatments and it is probable to belong to the class of aromatic glucosinolates. Kestwal et al (2011) reported an increase in the aromatic glucosinolates content in case of sulphur treatments, and most likely this is also the case of Na2SO4 treatment.…”

Sprouts are very rich in antioxidants (e.g. phenolic compounds) and their consumption is beneficial for humans' health. The sprouts' antioxidant properties are correlated to conditions of growth and maturity stage. The present study reveals the influence of maturity stage (5-, 7-and 9-day-old) and two sodium salts, NaCl and Na 2 SO 4 (10 mM and 100 mM) on the antioxidant capacity and total phenolic content of cauliflower and broccoli sprouts. The analysed sprouts' extracts were obtained in two phases, using ethanol 70% with 0.01% hydrochloric acid. In the case of cauliflower, the 7 days germination leads to the highest total phenolic content and radical scavenging capacity. Broccoli sprouts revealed the most enhanced DPPH radical scavenging capacity and total phenolic content at 5-day-old. The two sodium salts, generally, had positive effects on global antioxidant status. It is highlighted both for broccoli and cauliflower, the stimulating effect of 100 mM Na 2 SO 4 on the total phenolic content and soluble dry weight, but the DPPH radical scavenging activity was more important in the case of NaCl, than Na 2 SO 4 treatments, except for cauliflower sprouts treated with 100 mM Na 2 SO 4 . In conclusion, germination under adequate salt stress is a protocol to be considered in order to improve antioxidant properties of broccoli and cauliflower sprouts, despite the non-convenient effects on the germination and sprouts growth. Further researches are needed to optimize the level and time periods of such treatments.

“…In this study levels of total glucosinolates including glucoraphanin were increased in S supplemented radish, broccoli and cabbage sprouts. Levels of total phenolics were higher in S supplemented radish, but not broccoli or cabbage sprouts, and antioxidant activity was higher in S supplemented radish and broccoli but not cabbage [78].…”

“…This may have been due to salt stress at the concentrations used [3]. In the study of Kestwal et al (2010) broccoli, radish and cabbage seeds were sprouted in soil supplemented with S as sodium thiosulphate (Na2S2O3) at S concentrations equivalent to 20 to 60 kg/ha. This range was selected following an initial experiment to determine the optimal treatment range where sprout growth was not significantly adversely affected.…”
