The segments were chopped
into 0.5 5–6 cm pieces, using a vegetable cutting machine. A
pooled batch of about 18 kg chopped cabbage was stored in a plastic
bag under dark refrigerated conditions (4 ± 0.5 C) for 4–5 days
and was utilised as the raw material for all subsequent treatments.
A 50-g sample was taken from the pooled batch (in duplicate) as a
reference for fresh, unprocessed cabbage
