Abstract

A total of 45 random samples of ready to eat egg-based deserts including cream caramel, cake and jatooh products (15 samples each), were collected from different retailers, supermarkets, confectionery shops and bakeries in Assiut City. To assess their quality, the samples were examined microbiologically for the incidence and counts of aerobic plate count, psychrotrophs, enterococci, coliforms, fecal coliforms, Eschericia coli, Bacillus cereus, Staphylococcus aureus, anaerobes and yeasts & molds. The obtained results verify that the total bacterial and psychrotrophs counts averaged 1x105 and 1x106, 1.9x106 and <102, 2.6x105 and 1.1x105/g of cream caramel, cake and jatooh samples, respectively. Enterococci averages were <102, 2.5x102 and 1.2x104/g of the examined samples, respectively. Most of the examined samples of cream caramel and cake products (93.3 and 86.7%) failed to yield coliforms (less than 3/g), while 60% of jatooh samples had counts below 102/g. Two samples (13.3%) of such product yielded counts over 103/g. Fecal coliforms could not recover from all of cream caramel samples (<3/g), while most of the jatooh samples (53.3%) were contaminated by numbers ranged from <10 up to <103/g. Only one sample (6.66%) of such product had fecal coliforms more than 103/g. E. coli could not be detected in any of the examined egg-based deserts samples. Bacillus cereus could be isolated from 20, 20 and 46.7% in numbers averaged 6.7x103, 3.5x103 and 5.3x103/g of the examined samples, respectively.  S. aureus could not be detected in any of cream caramel samples. The organism recovered from 6.6 and 13.3% of the examined cake and jatooh samples, respectively. The incidence of anaerobes was 33.3, 73.3 and 80% in the examined products, respectively. Yeasts & molds contaminated 46.7, 60 and 100% of the examined products, respectively. They existed in numbers averaged 1.8x102, 6.7x102 and 2.2x104/g of the samples, respectively. The results prove that most of the examined egg-based deserts products are of quite good quality, except jatooh product that needs to be improved. However, the microbial loads are below the hazard point, the health hazard of such microorganisms still exists, if they are allowed to grow and multiply. Suggestive measures for improving these products were discussed.
