Effect of chitosan concentration (1 and 2% w/v) on internal quality of eggs coated with chitosan prepared withoutdeproteinization step was evaluated during 5 wk of storage at 25othe internal quality of eggs than with 1% chitosan. Coating with 2% chitosan increased the shelf-life of eggs by about 2 (basedon yolk index) or 3 (based on Haugh unit) wk at 25oC compared with that of noncoated eggs. Use of chitosan prepared withoutdeproteinization step as an egg coating material is advantageous in view of considerable reduction in chitosan production cost.
