2.2. Carrot sample preparation
Fresh carrots (Daucus carota subsp. sativus variety Nantes) were
collected within 24 h after being harvested at commercial maturity
(typically at the age of 18 weeks after seeding) from local growers
(Branxholme, Invercargill, New Zealand). On arrival, the carrots were
visually screened based on similarity in colour (ripening indicator),
shape (cultivar indicator) and size (quality indicator) then stored
at 4 °C until use. The carrots with bruised, damaged and infected
areas were excluded from the study. Carrot samples were randomly
taken and approximately 15 to 20 mm of both the crown and root
parts of the carrots were discarded to produce a carrot sample with approximately
80 mm in length. Since the quality of carrots would change
over the storage period, a reference sample (untreated carrot) was
prepared simultaneously with the PEF-treated carrot samples for each
replicate
