Low-calorie products are developed particularly for people with specific dietary re-
strictions. The purposes of this study were 1) to determine the acceptability of mango
juice, which contained one of five high-intensity sweeteners in lieu of sucrose and
3.0% fructooligosaccharide, in a 100-ml aseptic pouch and 2) to determine the shelf-
life of these products using two multivariate statistical analyses: principal component
analysis (PCA) and hierarchical cluster analysis (HCA).
Six samples of mango juice were formulated in a sweetness equivalent to that
obtained with 7% sucrose, and all of the samples contained 3.0% FOS
Sweeteners applied:
1.100:50:1 acesulfame-K:sucralose:neotame blend
2.Stevia with 97% rebaudioside A
3.Neotame
4.Sucralose
5.1:1 thaumatin/sucralose blend
6.Sucrose
The samples were presented in balanced block design (sequential monadic).
The acceptance tests were carried out in individual air-conditioned booths with white light
using 150 mango juice consumers. The samples were stored at a temperature of 20 C
degrees and analyzed after 0, 60, and 120 days.
The consumer data were analyzed by multivariate PCA to show the internal preference map
and HCA to group the consumers by preference dissimilarities.

After 120 days of storage, all of the samples presented preservation of acceptance
with an increase in sweetness
The aseptic pouch system was found to be a good way to preserve the acceptance
of ready-to-drink mango juice with sweeteners and FOS during 120 days of storage
The HCA and PCA were important and, in this case, complementary because the
