Rinse Dry And Package

After leaving the washer, eggs are rinsed in hot water. Rinse water containing chlorine or quaternary ammonium sanitizers may be used, provided they are compatible with the washing compound. Iodine sanitizing rinses may not be used.

Eggs are then blown dry with ambient air, at which point the surface temperature of the egg reaches approximately 35°C. Anderson et al.[5] found that the internal temperature of eggs continues to rise due to the high shell surface temperatures as well as candling lights. Five minutes after the eggs were processed, their internal temperature was seven to eight degrees above their initial temperature.

Shell eggs may be coated with mineral oil to slow the aging process, provided operations are conducted in a manner to avoid contamination of the product. Processing oil that has been previously used and that has become contaminated can be filtered and heat-treated to 82°C for three minutes prior to reuse.
