ABSTRACTFederal Specification!C-E-271 entitled Eggs, Shell^requires that not more than jf> can be packed with the small end of the egg up. The inability of some egg packers to consistently comply with the tolerance prompted an investigation to determine the importance of the position of the egg on quality after shaking to simulate transportation and long term Btorage.Three experiments were conducted. In each experiment one-half of the eggs were stored with the small end down and one-half with the small end up. For experiment 1 the eggs were stored quiescently for up to 6 months. For experiment 2 one-half of the eggs were shaken for 3*5 hours prior to storage. The eggs were stored for up to 7 weeks. For experiment 3 one-third of the eggs were stored quiescently, one-third were shaken for 2.5 hours and one-third were shaken for 7.5 hours prior to storage for up to Ik weeks.•'Results.*-show that without shaking the storage time influences the deterioration of the quality of the eggs to a greater extent than the position of the egg does. 1 Results of experiments 2 and 3 indicate that shaking is, in general, the most important factor and storage time and position of the eggs assume a less important place in -influencing changes in egg weight, albumen height, and quality score. However,-the inter! or quality, as measured by the amount of deterioration found, was better maintained in the eggs stored small end up. Shaking of the eggs resulted in more deterioration than in eggs not shaken./ Based upon the results of this study the requirement restricting the percentage of eggs that may be packed small end up will be disregarded and will be deleted from the specification in future revisions of the document.
