5. Conclusion
The addition of maltodextrin gels as fat replacers in confectionary
fillings resulted in changed textural properties of final
products. Reduced fat confectionery fillings expressed higher
firmness values, regardless the maltodextrin type, in comparison to
full fat confectionery filling which served as a control sample.
Confectionery fillings prepared with 20 g/100 g of potato or waxy
maize maltodextrin gels expressed slightly lower firmness value
than systems prepared with 15 g/100 g maltodextrin gels at same
fat replacement level, due to lower aw values of 20 g/100 g maltodextrin
gels. The increase in the amount of maltodextrin gel from 5
to 15 g/100 g, regardless the type and gel concentration, resulted in
decreased L* parameter, i.e. the fat reduced systems were darker.
According to sensory evaluation performed by trained panellists, it
was determined that 5 g/100 g fat reduced systems expressed
slightly better sensory properties in comparison to control sample.
Moreover, the results of total score method revealed that most of
the fat reduced samples were sensory acceptable. The results of
hedonic test performed by untrained panellists revealed that control
filling and the samples which were scored with the highest and
the lowest rate by trained panellists were sensory acceptable. Taste
of reduced fat systems was insignificantly different from control
sample. Confectionery fillings with reduced fat content were scored
with higher rates than control sample concerning odour property.
On contrary, texture/chewiness was better for control sample than
for fat reduced systems. However, 5 g/100 g fat reduced systemwas
characterised by the lowest standard deviation values for hedonic
test sensory scores which implies that this system was the most
uniformly scored. Consequently, 5 g/100 g fat reduced system was
more sensory acceptable than the other tested systems.
