The PLS regression of data allows for the identification of which
attributes, in the intensities presented, influenced acceptance of the
mango nectar samples positively or negatively in an interval of
confidence of 95% in each evaluation time. Sweet aftertaste and bitter
aftertaste affect the acceptance negatively in Day zero. Those attributes
are not expected in mango nectar but are common when sucrose
replacers are used (Cadena & Bolini, 2011). At 60th day of storage,
acid aroma and acid taste, attributes related to the deterioration of the
samples, affect the acceptance negatively, even as sweet aftertaste. At
the end of the study, at 120th day, only bitter aftertaste affected the
sample acceptance negatively. Probably with the increase in all samples,
sensory attributes related to sample deterioration did not influence the
sample acceptance with an interval of confidence of 95%.
