Abstract
|
|
|
This study aimed to assess the effect of temperature alterations on the preservation of egg quality and determine suitable temperature management practices for unwashed eggs contaminated with Salmonella Enteritidis on their shells in an actual distribution environment. Unwashed eggs inoculated with Salmonella Enteritidis were stored for 7 d under six different conditions, constant temperature storage at 25°C and five different temperaturechanging storage conditions. For the temperature-changing conditions, the eggs were initially stored at 25°C, and then the temperature was changed to either 10 or 35°C. The indicators of egg quality, air cell height, weight loss, and specific gravity were preserved in the initial measurements when the storage temperature was lowered from 25 to 10°C from day 3 to 4 after inoculation with Salmonella Enteritidis. In addition, the thick albumen ratio did not show significant alteration caused by the storage conditions when compared with that of fresh eggs. These findings indicate that lowering the storage temperature from 25 to 10°C is appropriate for the safety management of unwashed eggs during
actual distribution.
