Color Measurement of Egg Yolks–An Instrumental Method
Poultry Science, 1977 Abstract A rapid, instrumental method of measuring egg yolk color for routine quality control is described. The method utilizes the Hunter D25 Color and Color Difference Meter, and is comparable in speed and accuracy to that of visual method. Egg yolks ranging in color from light yellow to red were obtained by incorporating crystalline lutein, β-apo ...

Evaluation of Carotenoid Pigments for Coloring Egg Yolks
Poultry Science, 1960 Abstract MUCH has been written about the role of ingested xanthophylls for pigmenting broilers and also for coloring egg yolks. The great majority of this past research, however, involved the feeding of natural ingredients as yellow corn, corn gluten meal, and alfalfa meal, etc., rich in xanthophylls or crude concentrates made from these natural ...

The Effect of Light on Color of Egg Yolk Solids
Poultry Science, 1971 Abstract INTRODUCTION For some time egg yolk processors have been concerned with retaining desirable color in stored egg yolk products. Bornstein and Bartov (1966) refer to “optimal-yellow” in egg yolks as “appetizingly pretty.” Yolk color is important to such processors as bakers and manufacturers of macaroni products who value the color that yolk ...
