The first two components explained 82.34% of
the total variance.The biplot of principal component 1 (PC 1) vs.
principal component 2 (PC 2) is shown in Fig. 6. The first principal
component (PC 1) accounted for 60.17% of the total variation in the
data. The winy aftertaste and surface moisture attributes had positive
loadings, while the overall preference, fruity aroma and
sweetness/acidity attributes displayed negative loadings. The PC 1
(x-axis) shows that the control and Aloe vera coated kiwifruit slices
(left of the graph) differed from the chitosan-AC and alginate coated
kiwifruit slices (right of the graph), most notably with the regard to
the attributes identified in PC 1. The second principal component
(PC 2) accounted for 22.17% of the total variance, and the firmness
and color attributes showed positive loadings. It seems that
chitosan-AC coated kiwifruit slices are characterized by apparent
surface moisture and a winy taste. On the other hand, a fruity aroma
and sweetness/acidity were attributes primarily related to the
