Odour quality of spray-dried hens' egg powders: The influence of composition, processing and storage conditions

► PUFA enrichment and spray-drying temperature do not affect the odour of egg powders. ► Whole egg powders possess a stronger odour than egg yolk powders. ► Storage time and temperature increase the odour intensity of egg powders. ► There is a good correlation between sensory and instrumental analyses. ► Nine compounds are the most potent odorants for whole-egg and egg-yolk powders.
