3.1.2. Acceptance and ranked preference upon tasting
Within the three vegetable types, there were significant differences
in acceptance and ranked preference for cauliflower
(p = 0.0002 and p < 0.0001, respectively) and beans (both
p = 0.003). Sweet potato samples were all equally accepted and
ranked the same for preference, regardless of the way they were
prepared. Post-hoc testing showed that boiled was accepted more
than baked white cauliflower (Fig. 1). Stir fried green beans were
accepted less than yellow boiled beans.
Ranked preference data were in agreement, but somewhat more
discriminating (data not shown). White and green boiled cauli-
flower were preferred to baked white cauliflower. The boiled yellow
beans and the short boiled green beans were preferred to
stir fried green beans.
Across all samples baked or stir fried was less accepted than the
remaining preparation methods, whereas difference in cooking
time (boiled versus short boiled) and in colour did not affect
acceptance.Statistical analysis across the three vegetable types found no
significant differences in acceptance between vegetable types, neither
within comparable preparation methods as well as across vegetable
type overall.
