in Milk]]>Al-OtaibiM.M. SalehaF.A. Al-ObaidR. 1201381There is an increasing demand by consumers for food products with functional
properties. Date Syrup (Dips) has high contents of total sugar and contains
many functional components such as polyphenols, carotenoieds and phytosterols.
The objective of this study was to monitor the growth and survival of two probiotic
bacteria, Lactobacillus acidophilus La-5 and Bifidobacetrium lactis
Bb-12 in milk with different concentrations of dips during fermentation.
The L. acidophilus count increased gradually in all the samples up to
12 h of incubation. Later on, the bacterial counts decreased after 24 h of incubation
in all the treatments containing dips. However, the count of B. lactis
did not change significantly after 6 h. incubation for all the samples while
it decreased significantly after 12 and 24 h incubation in the samples containing
10 and 15% dips while it increased in the control until 12 h. and decreased
after 24 h incubation. Besides, an inverse relationship was observed between
the dips concentration and the growth rate of both the probiotic bacteria.
Subsequently, the acidity of milk increased in the control while it decreased
with increasing the dips concentrations and the pH values. The results
indicated that both the probiotic bacteria B. lactis and L. acidophilus
can remain viable with count of = 106 cfu mL-1 in presence
of dips concentration up to 20% during fermentation except for the treatment
with 20% dips in the presence of B. lactis after the 24 h. The
study results showed an excellent potential for incorporating the dips
in other probiotic dairy products.]]>El-Gawada, A.I.A., E.M. El-Sayeda, S.A. Hafez, H.M. El-Zeinia and F.A. Saleh,2005153744El-Gawad, A.I.A., E.M. El-Sayed, S.A. Hafez, H.M. El-Zeini and F.A.
