Abstract:
The shelf life of confectionery products can be
changed commonly during storage and
transportation. In this study, accelerated shelf life
estimation (AST) and transit trial (TT) in selected
confectionery products (hard candy, center filled
chewing gum and jelly) were focused and the
properties of confectionery samples were
compared with the commercial products. Test
sample and control sample were stored in climate
chamber at 35/40ºC and 50/80% RH and test
reference sample and control reference samples
stored at finished good ware house <30 ºC. The
samples were evaluated once a week along 21
days period. For TT, the samples were
transported to the distance and returned back
(850Km). Product’s physical and packaging
properties were evaluated by visual methods and
moreover, organoleptic parameters were checked
according to 5-point hedonic scale. The data were
analyzed using analysis of variances (ANOVA)
followed by Friedman Test at 0.05 significance
level. Comparative test was done by test sample
comparing with the other three of samples.
According to the results, all of the quality
properties were decreased with the storage
period. Hard candy and center filled chewing gum
specifically showed the textural changes but jelly
samples had no changes in AST. Moreover, hard
candy and jelly samples showed no significant
differences in TT but chewing gum samples were
showed somewhat differences. The overall
qualities of the sample showed the more or less
exact quality properties with the commercial
products.
