The lutein and zeaxanthin deposition in egg yolks of hens was evaluated. The effects of various levels of extracts from Mexican marigold flowers in hen diets were compared in Experiments 1 (from 0 to...
Four different clays were compared for their capacities to adsorb chlorophyll and carotenoids; two major pigments in vegetable oils at 30 and 100°C. The clays used include Fulmont, Tonsil N, Tonsil AC...
Lycopene has been identified as a phytochemical with potentially protective health benefits.
Interest in carotenoids has increased over the past decade from scientists involved in a variety of disciplines. Although some human nutritionists have focused their efforts on the potential role o...
The term “health promotion and disease prevention” has generally become euphemistic for measures to retard or avert the development of chronic diseases common to populations in affluent countries i...
It is not known whether the protective effects of antioxidants on cataract observed in experimental animals are relevant to age-related opacities in humans.
Garito and co-workers have suggested a mechanism to dramatically increase the second hyperpolarizability, gamma, in linear pi-electron-conjugated molecules. Polarization is introduced that leads to a ...
The effects of electric fields on the absorption spectra of the carotenoids spheroidene and spheroidenone in photosynthetic antenna and reaction center complexes (wild-type and several mutants) from p...
Background: Carotenoids and vitamin C are thought to be associated with reduced cancer risk because of their antioxidative capacity.
ISA Brown hens were fed diets supplemented with the synthetic carotenoids Carophyll Red and Carophyll Yellow at 20 and 15 mg/kg, respectively, lutein at 250 mg/kg, and the algae Chlorella at 12.5 g/kg...
The present study investigated the effect of 1 and 2% feed supplementation with biomass of Chlorella grown through heterotrophic fermentation on the concentration of total and individual carotenoids i...
The carotenoid tradeoff hypothesis states that diet-derived carotenoids are tradedoff among competing physiological demands, but this statement is rarely tested in ornamented females. The following di...
The relationship between the body accumulation and excretion of β-carotene and lycopene was elucidated. A lycopene-free diet was fed to seven healthy women's university researchers and students, and t...
