The results of Figs. 1 and 2 also demonstrate that the firmness of
the fermented milks was enhanced significantly (p < 0.05) not only
by inulin addition as a prebiotic (14% increase as an average), but
also by an increase in the time of cold storage (13% increase as
an average). As far as the effect of storage time on firmness is concerned,
such an increase was consistent with the effect of time on
the moisture content during storage
