4. Conclusions
Fat reduction and inulin addition increased the density of the low-fat ice creams compared that of the control ice cream. Fat reduction caused the yellowness (b*) of the low-fat ice creams to decrease while fat reduction and inulin incorporation had no effect on the redness (a*) of the samples. Inulin addition significantly decreased the melting resistance of the inulin-containing low-fat ice creams compared with that of the control ice cream. The melting rate of the inulin-free low-fat ice cream was not significantly different from that of the inulin-containing ones. The rise in the inulin content caused the hardness of the inulin-containing samples to decrease significantly compared with that of the inulin-free low-fat ice cream.
