Description
Egg shell sanitizing practices are necessary to improve microbiological safety of fresh eggs. In this work, fifteen fresh eggs samples of each (Balady, White and Brown eggs) were collected from different local supermarkets to evaluate their microbiological quality. The results indicated that Balady eggs were higher in microbial population in comparison with the two other varieties. Salmonella spp. was detected in 9 (60%) samples of Balady eggs. The effect of gamma irradiation at dose of 0, 2, 3 and 4 kGy on microbiological quality of Balady eggs during storage at 4±1 degree C for 35 days was studied. The effects of irradiation and storage on total cholesterol, and total carotenoids contents in Balady eggs were also investigated. The results showed that irradiation at 3 kGy reduced total aerobic bacterial counts. Coliform bacteria, E. coli and Salmonella spp. were completely eliminated. Total cholesterol and total carotenoids were decreased in yolk egg as a result of irradiation. Treated Balady eggs with irradiation dose of 3 kGy were efficient and sufficient for ensuring safety, maintain quality and extend shelf-life.
