| description | Salting is one of the most popular preservation methods for eggs. Therefore, there is a need for adequate information on how egg compositions change during the
salting period. Fresh duck eggs were obtained and divided into five sampling groups including a group of fresh eggs. All sample groups except the fresh eggs group were immersed in a 30% brine solution (w/v). A sample group was taken out of the brine in the first, second, third and fourth week of salting period respectively. The mean values for the changes in composition were recorded from the start of salting time up to the 28th day of salting. The components of eggs determined were moisture and salt content, oil exudation as well as protein content. Moisture content for both egg white and yolk decreased gradually
(p<0.05) from 74.28% to 66.97% for egg white and 35.66% to only 7.61% for egg yolk by the end of salting time. Meanwhile, there was a significant increase (p<0.05) in the salt content of egg white from 0.78% to 6.46% as the salting time increased. Increase in oil exudation of egg yolk was also observed during salting at p<0.05 ranging from 17.99% to 71.20%. Next for protein content, there was an
increase (p<0.05) in protein concentration during salting for both egg white and yolk. The range of mean values for duck egg white and duck egg yolk were around 1.36 mg/ml to 1.61 mg/ml and 2.79 mg/ml to 8.15 mg/ml respectively. In this study, the gradual change in proximate changes in fresh eggs and eggs salted at different time could be determined. |
