摘要： The objective of this research was to investigate and compare the effect of rapeseed oil, 0.5% beta cyclodextrin (beta-CD) and rapeseed oil/0.5% beta-cyclodextrin coating on egg quality attributes during storage for 28 days at 25 degrees C. Egg quality attributes such as weight loss (WL), air cell depth and diameter, Haugh unit (HU), albumen pH, yolk index and colour, eggshell strength and morphology were monitored. Similar initial quality attributes of control, rapeseed oil, 0.5% beta-CD and rapeseed oil/0.5% beta-cyclodextrincoated eggs were obtained at day 0. Control (uncoated) and beta-CD-coated eggs had the worst WL, air cell diameter, air cell depth, albumen pH and a* values after storage for 28 days at 25 degrees C, while the rapeseed oil/0.5% beta-cyclodextrin-coated eggs had lower values of air cell diameter (18.20 mm), air cell depth (7.20 mm) and albumin pH (9.12), higher eggshell breaking strength (51.21 N) and a*(25.33). At day 7 and 21, the best quality attributes were obtained by rapeseed oil/0.5% beta-cyclodextrin-coated eggs, being respectively: WL, yolk index and L*. Less obvious micro-cracks on the eggshell surface were detected especially in rapeseed oil/0.5% beta-cyclodextrin-coated eggs, which maintained slightly improved egg quality attributes during storage.
