Rheological characterization and sensory evaluation of a typical soft ice cream made with selected food hydrocolloids.Abstract
The effect of two novel hydrocolloids known as Balangu seed gum (BSG) and palmate-tuber salep
(PTS) with carboxymethylcellulose (CMC) on the rheological
characteristics of a typical soft ice cream was studied. The power law
model well described the flow behavior of mixes with a high correlation
coefficient (r). The flow behavior index was in the range of
0.450-1.154, while the consistency coefficient varied from 0.051 to
6.822 Pa s(n). All mixes showed a pseudoplastic behavior except the mix
containing 0.3% PTS, which was found to have a slightly dilatant
characteristic. An increase in the concentration was accompanied by an
increase in the pseudoplasticity and consistency coefficient. The effect
of selected gums on some sensory properties of a soft ice cream such as
viscosity, coldness, firmness, degree of smoothness (coarseness),
liquefying rate, body and texture and total acceptance has also been
investigated in this work. The correlation between the apparent
viscosity and sensory attributes has been determined because of the
importance of viscosity in the quality evaluation of an ice cream.
Taking into account the commercial ice cream properties, a 0.4% BSG gum
concentration may be recommended.
