Microalgal production of zeaxanthin

Algal Research, 2021
Abstract Zeaxanthin is a carotenoid pigment used in the food industry as well as in supplements for age-related macular degeneration. There is potential for microalgae to be used for zeaxanthin production, however there is relatively little work examining this issue, particularly with respect to scale-up.

Zeaxanthin is bioavailable from genetically modified zeaxanthin-rich potatoes

European Journal of Nutrition, 2008
The carotenoid zeaxanthin accumulates in the human macula lutea and protects retinal cells from blue light damage. However, zeaxanthin intake from food sources is low. Increasing zeaxanthin in common foods such as potatoes by traditional plant breeding or by genetic engineering could contribute to an increased intake of this carotenoid and ...

Synthesis of Zeaxanthin Esters

Russian Journal of General Chemistry, 2020
Six new zexanthin esters with 4-methylbenzoic, phenylglycolic, 2-hydroxybenzoic (salicylic), and nicotinic acids, ibuprofen, and ketoprofen, as well as benzoic acid ester, have been synthesized in anhydrous medium at 40°C in the presence of biocatalysts, Amano Lipase PS and Novozyme 435.

Zeaxanthin

Zeaxanthin is one carotenoid molecule commonly found in a variety of fruits and vegetables, such as yellow corn, saffron, orange juice, honeydew, goji berry, paprika, spinach, kale, romaine lettuce, zucchini, and brussels sprout. It is the pigment that provides red, yellow, and orange colors to many plants and even can be found in animal products like ...

Zeaxanthin Dependent and Zeaxanthin Independent Changes in Nonphotochemical Energy Dissipation

Journal of Plant Physiology, 1994
Summary The influence of zeaxanthin on high-energy-state quenching (qE) of room temperature chlorophyll fluorescence and on the quantum yield of oxygen evolution(ФO2) has been studied with isolated spinach thylakoids. A set of three different pretreatments was tested which all led to thylakoids with high contents of zeaxanthin.

Stabilization of liposomal membranes by carotenoids: Zeaxanthin, zeaxanthin glucoside and thermozeaxanthin

Materials Science and Engineering: C, 2008
We investigated the membrane-stabilizing effect of three synthesized polar carotenoids, thermozeaxanthin (TZ), zeaxanthin glucoside (ZG) and zeaxanthin (Z), using the fluorescent calcein-leakage measurement from the calcein-entrapped liposomes composed of dipalmitoylphosphatidylcholine (DPPC).

Zeaxanthin biofortification of sweet-corn and factors affecting zeaxanthin accumulation and colour change

Archives of Biochemistry and Biophysics, 2015
Zeaxanthin, along with its isomer lutein, are the major carotenoids contributing to the characteristic colour of yellow sweet-corn. From a human health perspective, these two carotenoids are also specifically accumulated in the human macula, and are thought to protect the photoreceptor cells of the eye from blue light oxidative damage and to improve ...

Screening sweetcorn for enhanced zeaxanthin concentration

Journal of the Science of Food and Agriculture, 2009
AbstractBACKGROUND: New varieties of fruits and vegetables, with higher carotenoid levels, are being developed to improve the potential health benefits to consumers. To assist the development of a new variety of high zeaxanthin sweetcorn, an analytical screening method was developed, including chromameter measurement of hue angle and optimized ...

Enzymatic Resolution of Zeaxanthin

Biocatalysis, 1992
Enzymatic esterification of optically inactive zeaxanthin with propanoic or palmitic acid in hexane with Candida cylindracea lipase gave the corresponding (3R,3′R)-diesters in 20% and 50% ee, respectively. When using the optically pure enantiomers the enzymatic esterification rate of (3R,3′R)-zeaxanthin was higher than for the enantiomer.
