Thefirstprincipalcomponent(D1)separatedtheformulations in terms of the presence of sugar and/or sugar substitutes.
On the extreme left side were the formulations without these
ingredients (pure juice (PUR) and pure juice with probiotic
(PRO)); in the centre were the added oligofructose juices (PRE
and SYNB); and on the right were the added sugar (SAC) or
sucralose (SUC and SUC-P) products. The second principal
component (D2) separated the formulations based on the presence of a probiotic culture, as the added probiotic formulations
(PRO, SYNB and SUC-P) were above the axis. The third principal
component (D3) separated mainly the formulations with added
sugar (SAC; upper axis) from those with added sugar substitutes
(SYNB, SUC and SUC-P; bottom axis). These results indicate that
the addition of sucrose, sugar substitutes (oligofructose or
sucralose) and probiotic cultures resulted in clarified apple juice
with different sensory characteristics, as demonstrated by
ANOVA (Table 3).
