The vegetables used (carrots, green beans and broccoli) were
each purchased fresh on three separate occasions from a local
supermarket on the day of processing. Edible portions (N 900 g) of
each vegetable were divided equally into three samples and
vacuum packed immediately at Food Science Australia, North
Ryde. Two of the samples were subjected to HPP at either
600 MPa or 400 MPa for 2 min whereas the third sample remained
untreated. All samples were stored overnight at 1 °C and trans-
ported to CSIRO Health Sciences and Nutrition in Adelaide on ice
the following day. The samples were then stored at 4 °C until
analysis, which was within 48 h of arrival. On the day of analysis,
samples were finely chopped in a kitchen food processor immedi-
ately prior to analysis.
