Food Predictors of Plasma Carotenoids [PDF]

, 2013
Empirical prediction models that weight food frequency questionnaire (FFQ) food items by their relation to nutrient biomarker concentrations may estimate nutrient exposure better than nutrient intakes derived from food composition databases.

Enhancement of carotenoid-to-chlorophyll singlet energy transfer by carotenoid-carotenoid interaction

Biophysical Journal, 1992
The apparent quantum yield of singlet-singlet spirilloxanthin-to-bacteriochlorophyll a energy transfer increases linearly with the residual spirilloxanthin content in Rhodospirillum rubrum membrane vesicles from which this carotenoid has been partially removed.

Serum carotenoids are strongly associated with dermal carotenoids but not self-reported fruit and vegetable intake among overweight and obese women

International Journal of Behavioral Nutrition and Physical Activity, 2019
Background Accurate assessment of fruit and vegetable intake (FVI) is essential for public health nutrition research and surveillance. Blood carotenoid concentrations are robust biomarkers of FVI, but collecting blood samples typically is not feasible in

Environmental and Genetic Effects on the Composition of Palm Oil From Hybrid Plant Clones of Caiaué and Oil Palm

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT The interspecific hybrids (IEH OxG) obtained from the crossing of Elaeis oleifera (Eo) and Elaeis guineensis (Eg) are resistant to some diseases that affect Eg in some regions of South America, and commercial growing in several countries has been established.

New natural carotenoid sources. V. Chlorophyll and carotenoid content of Beta vulgaris

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 1989
Chlorophylls and carotenoid pigments were investigated in leaves of beet (Beta vulgaris L.) obtained from SDE Cluj-Napoca, harvested in September 1987. Leaves had a higher content both in chlorophylls and carotenoids than petioles.

Annatto‐Derived Carotenoids (Bixin and Norbixin) As Biodiesel Antioxidants: Characterization and Effects on Oxidative Stability (Rancimat and PetroOXY)

Journal of the American Oil Chemists' Society, EarlyView.
Annatto‐derived bixin and norbixin were characterized and evaluated as natural antioxidants for soybean biodiesel. Their antioxidant performance and effects on oxidative stability were assessed using DPPH, Rancimat, and PetroOXY methods. ABSTRACT The increasing use of eco‐friendly fuels is increasing the production of biodiesel but soybean biodiesel is

Comparative Profiles of Lipophilic Nutrients and In Vitro Antioxidant Activity in Commercial Arabica and Robusta Green Coffee Beans

Journal of the American Oil Chemists' Society, EarlyView.
Integrated compositional profiling of ten commercial green coffee lots showed higher mean total phenolic content, DPPH radical‐scavenging activity, β‐carotene, and total phytosterols in Robusta‐labeled lots, whereas Arabica‐labeled lots showed higher mean total tocopherols and total measured fatty acids.

Influence of Direct Saponification Conditions on Sterol Yield and Composition of the Unsaponifiable Fraction of the Microalga Isochrysis galbana and the Seaweed Ascophyllum nodosum

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Saponification is a key step for recovering the unsaponifiable fraction (USF) of lipids, which contains bioactive sterols, tocopherols, and carotenoids. This study optimized direct saponification conditions (50–300 g L−1 KOH; 60°C–100°C) to recover sterol‐rich USFs from the microalga Isochrysis galbana and the brown seaweed Ascophyllum nodosum,
