The h value of the ABCP was only slightly
reduced with increased extract concentration in puree (from 11.4
to 10.9).
The colour purity (C*) of PACP decreased at lower extract concentrations, however when it reached 1.2% C* started to increase
(Table 2). Interestingly, this transition was reflected in the colour
acceptability scores of PACP (Table 3); at 0.8 and 1% extract addition
the colour was less acceptable than the control sample or purees
with higher extract percentages. The C* of ABCP slightly increased
by increasing extract concentrations in purees. The total colour
difference of PACP with 2% extract additive was 12.8, and the total
colour difference of ABCP with the same percentage of extract was
only 1.1 (Table 2). The total colour difference values between 1 and
2 indicates slight differences that are perceivable only by a person
capable of distinguishing nuances of colours, while DE values
higher than 5 indicate large overall colour differences.
The extract additive increased soluble solids content and
reduced pH of the purees. Soluble solids in PACP increased from
20.5 (control) to 22.0 Brix (2% of extract) and in ABCP from 18.8 to
20.1Brix, respectively. The pH of PACP reduced from 3.45 (control)
to 3.30 (2% of extract) and that of ABCP from 3.34 to 3.18,
respectively.
