Abstract
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 5week 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 mPaS was used to prepare the coating solution The weight loss Haugh unit and yolk index values suggested that coating of eggs with shrimp αchitosan increased the shelf life of eggs by almost 4week at 22 ± 1 °C and 3week at 32 ± 1 °C compared with controls non chitosan coated and acetic acid coated eggs Threetime repeated coating was more effective in preserving the internal quality and preventing weight loss than with singletime coating of chitosan on egg Therefore threetime coating of eggs with 2206 mPaS chitosan offer a protective barrier for preserving the internal quality of eggs stored at tropical room conditions and concomitantly prevent contamination with microorganismsNT thank the University Grants Commission UGC New Delhi India and GKP thank the Department of Science and Technology DST New Delhi India for the award of Research Fellowship Authors thank Director CSIRCFTRI Mysore for his encouragement and permission to publish this work
