Publication number: 20200000128Abstract: An in-shell egg pasteurization process includes, in a temperature-raising stage (12), raising the temperature of yolk of a plurality of in-shell eggs (40), simultaneously and at least predominantly by means of microwave radiation, to a pasteurization temperature, the temperature-raising stage (12) including a plurality of elongate or longitudinally extending microwave cavities that are isolated from one another so that microwaves fed into an elongate or longitudinally extending microwave cavity do not leak into any other elongate or longitudinally extending microwave cavity. The in-shell eggs (40) are displaced along the lengths of the elongate or longitudinally extending microwave cavities whilst being irradiated with microwaves. In a pasteurization stage (14), the raised temperatures of the in-shell eggs (40) are maintained for a pasteurization time sufficient to pasteurize the in-shell eggs (40).Type: ApplicationFiled: February 19, 2018Publication date: January 2, 2020Applicant: CSIRInventors: Mathys Johannes Rossouw, Pranitha Dawlal

Patent number: 8071146Abstract: An in-shell egg pasteurization process (10) includes, in a temperature raising stage (16), raising the temperature of albumen of an in-shell egg predominantly by means of microwave radiation to a temperature between 57° C. and 60° C., the albumen temperature being raised at a rate which reduces at least once over time. Simultaneously, in the temperature raising stage (16), the temperature of an external surface of the egg is raised predominantly by means of external heat radiation or conduction to a temperature of between 57° C. and 70° C., or alternatively or in addition the egg surface temperature is allowed to rise to a temperature of between 57° C. and 70° C. as a result of the microwave radiation by inhibiting heat loss from the egg. Said temperatures are then maintained by means of microwave radiation and external heat radiation or conduction for at least some time.Type: GrantFiled: April 22, 2005Date of Patent: December 6, 2011Assignee: CSIRInventors: Corinda Erasmus, Mathys Johannes Rossouw
