2.1. Plant material and sample preparation
Radishes (Raphanus sativus L.) were purchased from a local
market in Mar del Plata, Argentina. They were kept at 5 ± 1 ◦C in
darkness prior to processing. Radish roots were separated from
leaves and washed in tap water to eliminate any surface contamination.
Then,they were cut with a manual cutter into slices of about
3–4 mm and washed again in tap water using a ratio of sliced radish
to water of 1:10 (w:w).
