Determination of sugars, organic acids, aroma components, and carotenoids in grapefruit pulps.
Food Chem. 205 , 112-21, (2016) The composition and content of sugars, organic acids, volatiles and carotenoids, in the pulps of six grapefruit cultivars, were examined by HPLC and GC-MS. The results showed that sucrose was the dominant sugar in grapefruit, making up 40.08-59.68% of the tot... |

In vitro bioaccessibility and monolayer uptake of lutein from wholegrain baked foods.
Food Chem. 174 , 263-9, (2014) Lutein-enriched foods would contribute towards promoting the consumption of this important carotenoid. In the current study cookies, muffins, and flatbreads were produced at three enrichment levels (0.5, 1.0 and 2.0mg lutein per serving) to investigate lutein... |

Correlations of carotenoid content and transcript abundances for fibrillin and carotenogenic enzymes in Capsicum annum fruit pericarp.
Plant Sci. 232 , 57-66, (2015) The fruits of Capsicum spp. are especially rich sites for carotenoid synthesis and accumulation, with cultivar-specific carotenoid accumulation profiles. Differences in chromoplast structure as well as carotenoid biosynthesis are correlated with distinct caro... |

Carotenoids of aleurone, germ, and endosperm fractions of barley, corn and wheat differentially inhibit oxidative stress.
J. Agric. Food Chem. 63(10) , 2715-24, (2015) The antioxidant potential of carotenoids from aleurone, germ, and endosperm fractions of barley, corn, and wheat has been evaluated. HPLC analysis confirmed the presence of lutein and zeaxanthin carotenoids (nd-15139 μg/kg) in extracts of cereal grain fractio... |

Analysis of (all-E)-lutein and its (Z)-isomers during illumination in a model system.
J. Pharm. Biomed. Anal. 100 , 33-9, (2014) Light induced-isomerization of (all-E)-lutein in organic solvent and starch model systems was investigated. Lutein and its (Z)-isomers were separated by HPLC using a C30 column and gradient mobile phase based on methanol-methyl-tert-butyl ether-water in 24min... |

Violaxanthin de-epoxidase disulphides and their role in activity and thermal stability.
Photosynth. Res. 124(2) , 191-8, (2015) Violaxanthin de-epoxidase (VDE) catalyses the conversion of violaxanthin to zeaxanthin at the lumen side of the thylakoids during exposure to intense light. VDE consists of a cysteine-rich N-terminal domain, a lipocalin-like domain and a negatively charged C-... |

Validated method for the analysis of goji berry, a rich source of zeaxanthin dipalmitate.
J. Agric. Food Chem. 62(52) , 12529-35, (2015) In the present study an HPLC-DAD method was developed for the determination of the main carotenoid, zeaxanthin dipalmitate, in the fruits of Lycium barbarum. The aim was to develop and optimize an extraction protocol to allow fast, exhaustive, and repeatable ... |
