Organoleptic scoring of fermented milk products prepared with
dibs
The organoleptic properties of resultant fermented milk made
with/or without adding of dibs (date syrup) are shown in Table
4. Zabady with 2% dibs and biogarde with 2% dibs had the
highest (pP 0.05) scores for flavor, appearance and body textures
with those of control; this may be due to the increasing
gel firmness and also improved the body textures. Fortification
with dibs up to 3% increased the organoleptic properties compared
with controls. The obtained data revealed that fermented
milks (zabady and biogarde) fortified with 2% dibs
gained the highest scores of organoleptic properties. Furthermore,
the average total score points of both tested treatments
gradually decreased by the prolongation of storage periods.
However, the panelists described the flavor of fermented milks
prepared with 2% dibs as more acceptable. These results may
be maintained by the data of HMF and Fe in Table 1., sulfur
amino acids in Table 3. Hence, it was limited to the highest
average score points of treatments to the proceeding chemical
characteristics, amino acid contents and microbiological tests.
