Colour
Colour was measured in a pineapple-water (4 : 1, w : v)
puree with a Hunterlab D25 A-9 Tristimulus Colorimeter.
A standard white tile having reflectance values of X
= 82.5 1, Y = 84.53, 2 = 10 1.23 was used as reference. A
representative sample of the puree was put into a plastic
dish (6 cm diameter and 1.5 cm high), and measured.
Each value represents a mean of a duplicate determination
of three different samples. Results were reported as
an average of in~vidual values as L (lightness), a (+a =
red, -a = green) and b (+b = yellow, -b = blue).
