To quickly assess the difficulty of the text, read a short excerpt:
They observed that the addition of beta-apo-8'-carotenal to the diet containing canthaxanthin did not improve visual scores. It is apparent from published data that it has not been possible to evaluate yolk pigmenting characteristics of canthaxanthin and beta-apo- 8'-carotenal which were fed in diets containing yellow corn. This prob- lem is apparently due to the different dominant wavelengths (actual color) of the pigments. Since color can be accurately described using the three variables of d...ominant wavelength, excitation purity and luminosity, it is unlikely that accurate evaluation of pigmentation in egg yolks can be accomplished by either visual or spectrophotometric analysis of acetone extracts using a constant wavelength. The purpose of this experiment was to analyze and define color characteristics of egg yolks when beta-apo-8'-carotenal and canthaxanthins when fed separately or in combination. These two xanthophylls were selected 40 because of the great difference in color imparted to the yolk by the two different compounds.
