How about an egg with white yolk? Possible?

Egg is considered a complete food and is consumed by millions of people all over the world. Over the centuries eggs are consumed in one form or the other, most common form being boiled egg, fried egg and omelette. What does one look when a boiled egg is prepared for eating? The rubbery egg white and grainy yolk yellow in color. While the egg white is made up of one of the richest proteins known to mankind, egg yolk is mostly made of fat thus providing a balanced protein-fat combination. What will any one feel when a boiled egg does not contain the normal yellow colored yolk? Probably will not accept it as a genuine egg! Shockingly Japanese generally do not think so and they seem to be favoring an all white egg with both the egg white as well as the yolk appearing white! How can such eggs be created in the farm? Read below how they are managing such a unique type of egg in that country.  

"While many of us prefer eggs with deep coloured yolks,people in Japan like to have eggs with whiter interiors. To keep the 'egg lovers' happy, farmers in Japan are constantly trying to rear chicken that lay eggs with white yolks. Eggs with yellow yolks usually get their colour from chicken feed that's made of imported corn. The eggs, which are laid by rice-fed hens, owe their unusual colour to the diet of the chicken. These eggs are known as Kometsuya—a combination of Japanese words kome (rice) and tsuya (luster). Several chicken farms have already started transitioning their birds to feed that is mostly produced locally, reported the Japan Times. "In the not-too-distant future, white sunny-side ups will be part of the daily cuisine for Japanese," says an official of Hokkaido Dosanko Plaza shop in Japan."

In to day's commercial farming system, boosting the yolk color is achieved by feeding the birds with diets containing high levels of  carotenoids, an yellow component present in grains like maize and most vegetables and colored fruits. It is well known that wheat based feeds invariably give pale yellow yolk compared to feeds based on maize. Those who like dark yellow color incorporate greens and other plant sources rich in carotenoids. Japanese who love white yolk were able to achieve this by scrupulously avoiding carotenoids containing ingredients and use white rice as the major component of the poultry feed. One wonders which other country will accept an egg that doe not contain the yellow yolk! A classical example of traditional food habits which are difficult to change easily!
