Chitosan coating.



Researchers wanted to see how a chitosan coating and various storage positions of eggs (small-end down, small-end up or horizontal) would affect the internal quality and shelf life of the eggs during five weeks of storage at 25 C.

Compared with noncoated eggs, all chitosan-coated eggs, irrespective of their storage positions, had significantly less weight loss, higher Haugh haugh

The portion of the egg of an animal that consists of protein and fat from which the early embryo gets its main nourishment and of
 index throughout the storage period. The chitosan coating, irrespective of the position of the samples during storage, extended the shelf life of the eggs by at least three weeks at 25 C compared with the noncoated eggs. Noncoated and chitosan-coated eggs placed small-end down tentatively had better quality than eggs placed small-end up after three and four weeks of storage.

After five weeks of storage, the different storage positions did not significantly affect the quality of either the noncoated or coated eggs. There were no notable differences in the total amino acid amino acid (əmē`nō), any one of a class of simple organic compounds containing carbon, hydrogen, oxygen, nitrogen, and in certain cases sulfur. These compounds are the building blocks of proteins.  content of the albumen al·bu·men
