Description The current investigation was conducted to study
the effectiveness of chitosan coating in preserving the internal
quality of table eggs stored under tropical room conditions of
32±1 °C and 60–70 % r. h. Internal, physical and microbiological
quality of eggs coated with chitosan was evaluated
during 5-week storage at different temperature (22±1 and
32±1 °C). Chitin was extracted from shrimp processing raw
byproducts and deacetylated to high quality chitosan. The
prepared chitosan was analyzed for its characteristic properties.
The chitosan with a viscosity of 2206 mPa.S was used to
prepare the coating solution. The weight loss, Haugh unit, and
yolk index values suggested that coating of eggs with shrimp
α-chitosan increased the shelf life of eggs by almost 4-week at
22±1 °C and 3-week at 32±1 °C compared with controls (non
chitosan coated and acetic acid coated) eggs. Three-time repeated
coating was more effective in preserving the internal
quality and preventing weight loss than with single-time coating
of chitosan on egg. Therefore, three-time coating of eggs
with 2206 mPa.S chitosan offer a protective barrier for preserving
the internal quality of eggs stored at tropical room
conditions and concomitantly prevent contamination with
microorganisms.
