OVOSHINE Ensuring food safety of eggs


Eggs are a common source of protein around the world. It is estimated that there are around 5 billion laying hens worldwide, the greatest number being in China with around 1 billion hens, while the European Union keeps around 380 million hens, making almost one laying hen per person in the world. The average number of eggs consumed per person is 215 eggs per year, varying greatly depending on the country. China is the country with the highest egg consumption (349 eggs per year) while an average Indian only consumes 47 eggs per year.

Current legislation in Europe does not allow any treatment on human consumption eggs except from ultraviolet sanitation. Most of the egg producers and packers do not include this technology because its low sanitation rate and high maintenance costs. The egg industry is now facing big challenges since the directive 1999/74 from the EU (which most of the EU countries will apply in 2012) in which the hen welfare has been increased, leading to higher costs for the egg industry. Moreover, the egg industry has been always in the point of view due to the Salmonellosis outbreaks that periodically occur in Europe. So, the image of the egg sector must be improved and the standardisation of a sterilisation system will be a real break-through for the sector.


The objective of this project is to develop a low cost, secure and fast UV system in combination with hot air to sterilise eggs. The proposed technology provides the following advantages:

OVOSHINE system will not increase the temperature of the egg above 45ºC.

A CONTINUOUS STERILISATION system will be used, to be inserted in the production or packing line, facilitating the installation in existing modern production lines.

THE SANITATION cost per egg will be below 0.001 €.

THE EGGSHELL will be illuminated by high energetic UV photons that will eliminate the bacteria.

THE DISINFECTION sprocess is both fast and of low cost, amounting to a very small contribution to the total egg cost.

NO CHEMICAL PRODUCTS will be used, thus eliminating egg contamination.

THE SANITATION rate of the system will be 10,000 eggs per hour.
