Internal quality attributes of chicken eggs coated with Hik (Lannea coromandelica) and Mango (Mangifera indica) wax stored at room temperature

Eggshell coating is a common practice used to improve the shelf-life of table eggs while mineral oils have been widely utilized as an effective material. Hik (Lannea coromandelica) and Mango (Mangifera indica) are tropical trees grown in dry zone Sri Lanka their wax has film-forming properties. However, information on using surface material egg quality attributes scarce yet be elucidated. Therefore, this study aimed check effect tree waxes external materials evaluate internal qualities shelf life during storage. A total 408 freshly laid, white, medium-sized (55–60 g), clean were purchased, individually weighed, arranged under completely randomized design obtain four different treatments as; 1) Negative control (non-coated eggs, NC), 2) Positive (mineral oil-coated PC), 3) Wax coated (HW), 4) (MW) stored at room temperature (27 ± 2°C) for five wks. Weight losses parameters (Haugh unit [HU], albumen yolk pH values, microbial analysis) measured weekly. Fourier transform infrared spectroscopy (FTIR) analysis was conducted analyze structural changes albumen. Results revealed that HW MW had low weight loss (p < 0.05) than NC eggs. Compared with NC, PC, significantly higher HU Both plant coatings effectively reduced when compared non-coated The color did not change > upon treatment. All negatively performed Salmonella test. FTIR confirmed no chemical occurred wax-coated In conclusion, oil, however, it still enhancing improving rather non-coating.
