Figure 1 presents the effect of hydrocolloids on the relative
sedimentation of cloud in litchi juice stored for a period of
1 month. Pectin did not effectively stabilize the colloidal
particles and thus the cloud precipitation was seen within 5
days of storage (Fig. 1a). Our results, however, differ from
the previously published results (Okoth et al. 2000;
Corredig et al. 2001) wherein addition of pectin led to stabilization
of the cloud. It is felt that the increase in cloud particle
size depends on the DE, the amount of pectin added,
and the method used to modify the pectins. However, it is
beyond the purview of this paper to elucidate the exact
reason for such results. It is felt that more studies related to molecular interaction need to be conducted to conclude the
same. Because addition of pectin did not stabilize the cloud
effectively, pectin was not further selected for the evaluation
studies.
