Abstract
The study was performed to investigate microbial and physicochemical properties of domestic liquid eggs during cold storage. The liquid eggs used in the experiment were whole liquid, liquid egg yolks, and liquid egg whites. All samples were analyzed in summer and winter. The aerobic microorganisms were 1,270-83,300 CFU/g from non-sterilized liquid eggs produced in summer and their numbers increased from those produced in winter (ND, ~4,330 CFU/g). Total coliforms were not observed in non-sterilized whole liquid and non-sterilized liquid egg yolk regardless of season. Total coliforms from nonsterilized products were not detected in liquid egg whites during cold storage. Salmonella sp. was not observed in any of the liquid egg products. However, Pseudomonas sp., Pseudomonas geezennei, Pseudomonas otitidis, and Pseudomonas aeruginosa were identified by 16S rRNA from non-sterilized whole liquid eggs produced in summer. The pH and viscosity of whole liquid eggs and liquid egg whites were not different between the sterilized and non-sterilized treatments during cold storage. These results suggest that managing cross-contamination is necessary when non-sterilized liquid eggs are processed in summer.
