This research was carried to evaluate the quality of labenah (concentrated yoghurt) sold in Suez canal province by determining some chemical and microbial properties of sixty samples, collected from different places in Ismailia and Portsaid Governorate in between December 2013 and July 2014 .
The chemical examination revealed that the mean value of Titratable acidity percent, total solids, fat and salt content was 1.934±0.076 %, 32.21±0.56 %, 16.93±0.60 % and 2.15±.03% respectively.
The results showed that 25 % and 35 % of samples did not comply with the (GSO) and (S.D.) respectively.
Bacteriological examination of samples declared that the mean value of total Mesophyilic, Psychrotophic, Coliforms and Escherichia coli count was 3.18x105± 6.1x104, 9.2x106 ± 2.4x105, 1.13x104±1.63x103 , and 3x103 ± 3.7x102 respectively.
Salmonella were not detected in all the examined samples of labenah.
Mycological examination of samples revealed that, yeast and mould count were high in all samples with mean value of 4.5x104± 9x103 , 5.3x103±1.4x103 , respectively.
The results revealed that the more frequent isolated yeast was the candida albican and candida tropicalis, while the most frequent isolated molud was Aspergillus and Mucor spp.
Public health importances of isolated micro-organisms as well as measures for improving the quality of the product were discussed
