Commercial quantities of deeply pigmented egg yolk are used by certain food manufacturers to give desirable yellow color to some of their products. Yellow com and alfalfa meal are the major natural sources of the yellow pigments (xanthophylls) found in the egg yolk. The degree of pigmentation depends largely on two factors, the pigment concentration in the diet and the amount of pigment absorbed by the yolk fat during yolk formation.
