Effect of coating table Eggs with plant oils and plastic coats on sensory evaluation during storage

Abstract

The objective of this novel study was to evaluate the coating of table eggs with some natural oils and plastic film and their effects on sensory evaluation of fresh eggs and after storage for 1, 2, 4 and 8 weeks. Fresh table eggs were distributed into two main treatments : the first, storage at room temperature and the second, storage at refrigerator temperature, each main treatment was sub divided into five groups as follow :1- Control group, 2-Corn oil group, 3-Dill oil group, 4-Black seed oil group . 5-Plastic film group were finstly wrapped with plastic film. All groups (except the control) was thermostabilization treated at 56.7ْC for16 min.. The data obtained revealed that fresh egg groups had acceptable flavor score ranged from 6.2 to 6.5 , these values were gradually verified (P<0.01) after storage for 8 weeks to be weakly acceptable and ranged from 4.1 to 5.0 at room temperature, and from 4.3 to 5.2 at refrigerator temperature for different groups. Fresh egg groups had acceptable 6.4 score appearance, no significant differences were appeared after storage for 8 weeks at room or refrigerator temperature. Storage eggs at room or refrigerator temperature for 4 and 8 weeks significantly (P<0.05) decreased appearance score compared with fresh egg groups. Coating table eggs with natural oils and plastic film reduce the deterioration in sensory evaluation of stored eggs. Using dill or black seed oils better than others were recommended.
