DSM releases its Egg Yolk Pigmentation Guidelines and a new color to YolkFan.
YolkFan provides a simple means of measuring yolk color and the addition of a new shade will help producers to cover the demand for highly pigmented yolks in markets like Japan and the Middle East.
YolkFan has been developed from the DSM Yolk Color Fan; recreating the original 15 colors with the addition of a deeper 16th shade.
YolkFan is an inexpensive and easy tool to use when testing the color of a yolk and the new shade reflects the tendency towards a deeper yolk color in several markets.
It is also used by digital egg testers as their calibration standard.
The link between pigmented eggs coming from healthy hens is being recognized widely and, as a consequence, consumers have begun to ask for a deeper shade of yolk color.
A bright yolk color can be considered an indicator of the good health status and performance of a flock, so a means to test the yolk color effectively is required.
In order to produce YolkFan, yolks were evaluated sensorially, optically and chemically and the perfect 16th yolk shade was selected by a team of scientists.
