American Journal of Food Technology1557-45711557-458XAcademic Journals Inc.10.3923/ajft.2009.1.8Al-OtaibiM.M. 1200941Eight commercial probiotic fermented milk products (six
full fat and two low fat) from Al-Ahsa markets were evaluated for chemical,
microbiological and sensory properties. The chemical composition parameters
ranged from 0.9-1.2% fat (low fat products), 3.0-3.9% fat (full fat products),
3.1-4.7% protein, 0.7-1.2% ash and 7.5-3.7% carbohydrate in all the milk
products. The pH values of all the products decreased significantly from
the production day to the end of storage period. With respect to the microbiological
side, the coliform bacteria, moulds and yeasts counts were not detected
in all the products during the refrigerated storage at 5 ±1 °C.
However, seven out of eight products contained over 106 cfu
mL-1 of bifidobacteria on the production day. Only two of these
products maintained 106 cfu mL-1 viable count of
bifidobacteria till the end of cold storage period. On the other hand,
three out of eight products showed the highest number of L. acidophilus
viable count (above 108 cfu mL-1) on production
day. The results of sensory evaluation showed that all the tested products
obtained high scores for flavor, appearance, texture or consistency and
smell (odor) properties during the storage period. These results suggest
that for optimum benefits, the probiotic fermented milk products with
live probiotic bacteria should be consumed within one week of their production
date. The research provided useful information to the dairy industries
to develop new technology to ensure the supply of high quality milk products
to the consumers.]]>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.
