The Dynamics of Energy Dissipation and Xanthophyll Conversion in Arabidopsis Indicate an Indirect Photoprotective Role of Zeaxanthin in Slowly Inducible and Relaxing Components of Non-photochemical Quenching of Excitation Energy

open access: yesFrontiers in Plant Science, 2017
The dynamics of non-photochemical quenching (NPQ) of chlorophyll fluorescence and the dynamics of xanthophyll conversion under different actinic light conditions were studied in intact leaves of Arabidopsis thaliana. NPQ induction was investigated during

Orange Capsicums and Chillies as a Potential Source of Dietary Zeaxanthin, an Important Macular Carotenoid for Eye Health

open access: yesProceedings, 2020
Zeaxanthin is a dietary carotenoid accumulated in the macula in order to reduce photoreceptor oxidation by blue light. Damage caused to photoreceptor cells in the human eye leads to macular degeneration, which is the leading cause of blindness in ...

Optimization of Ultrasound‐Assisted Extraction of Seabuckthorn (Hippophae salicifolia) Seed Oil With the Use of Response Surface Methodology

open access: yesFuture Postharvest and Food, EarlyView.
Ultrasound‐assisted extraction (UAE) of seabuckthorn seed oil enhanced yield (17.95%), antioxidant activity (IC50: 5.25 μg/mL), and carotenoid content (266.63 mg/100 g). The oil, rich in unsaturated fatty acids (83.15%), exhibited superior quality, thermal stability, and potential applications in food, cosmetics, and pharmaceuticals, making UAE a ...

Effects of LED Light Exposure on Lutein and Bioactive Compounds in Nasturtium Flowers (Tropaeolum majus L.)

open access: yesFuture Postharvest and Food, EarlyView.
Red LED supplementation during cultivation modulated the accumulation of bioactive compounds in Tropaeolum majus flowers. Moderate exposure (3–5 h) enhanced antioxidant capacity and increased carotenoids, phenolics, and anthocyanins depending on petal color, highlighting a simple strategy to improve the functional value of edible flowers. ABSTRACT This

Bee pollen as functional food and environmental bioindicator: current evidence and future challenges

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract Bee pollen (BP), a plant‐derived product collected by honey bees, is increasingly promoted as a functional food due to its content of proteins, essential amino acids, lipids, vitamins, minerals, and bioactive compounds such as polyphenols and flavonoids.

Reconstruction of the carotenoid biosynthetic pathway of Cronobacter sakazakii BAA894 in Escherichia coli. [PDF]

open access: yesPLoS ONE, 2014
Cronobacter sakazakii could form yellow-pigmented colonies. However, the chemical structure and the biosynthetic pathway of the yellow pigments have not been identified. In this study, the yellow pigments of C. sakazakii BAA894 were purified and analyzed.
