Blanching was carried out by immersing cabbage in hot water
using a wire mesh basket (cylindrical, 10 cm diameter and 15 cm
height). The basket containing 50 g cut cabbage was immersed in
a thermostatically controlled water bath (±0.5 C) containing 5 L
water. Blanching was carried out between 80 and 100 C with an
increment of 5 C. For all the temperatures, samples were withdrawn
every 2 min up to 14 min. The blanched material was
drained, cooled in ice water (1–4 C) for 1 min and then allowed
to drain for 30 s. The blanched samples were kept in a plastic
bag (20 25 cm) and colour and texture analysis were carried
out on the same day. The treatments were randomised and were
performed in duplicate. The processed samples were submerged
in liquid nitrogen and ground to a coarse powder using a mortar
and pestle and stored in plastic bags at 20 C until further analysis
(10–15 days).
