The color of the egg yolk depends on the absorption and deposition of the carotenoids in the hen diet and represents a visual characteristic of great effect on the product acceptance. Corn is commonly used as an energy ...

Plastidial isoprenoids, such as carotenoids and tocopherols, are important anti-oxidant metabolites synthesized in plastids from precursors generated by the methylerythritol 4-phosphate (MEP) pathway. In this study, we ...

Egg yolk color may be controlled both by the concentration and the type of xanthophylls added to diets, with the aim of meeting consumers demand. The objectives of this work were to study how yellow and red xanthophylls ...

The wavelength dependency of xanthophyll cycling in two marine microalgae (Thalassiosira weissflogii and Dunaliella tertiolecta) was studied by establishing biological weighting functions (BWFs) during exposure to natural ...

We evaluated the influence of dietry inclusion of corn gluten meal, apocartenoic acid ethyl ester (APO-EE), canthaxanthin, and Rhodocylus gelatinosus R-1 biomass on broiler carcass color. These oxycarotenoid sources were ...

Short-term ultraviolet (UV) radiation (280-400 nm) effects on xanthophyll cycle activity and photosynthesis were assessed during fluctuating irradiance (60- and 10-min cycles - saturating irradiance to near-zero irradiance) ...
