Food loss and waste are severe social, economic, and environmental issues. An example is the incorrect handling of waste or by-products used to obtain bioactive compounds, such as carotenoids.

Onions as an interesting ingredient have been proved to promote Z-isomerization of lycopene and increase bioaccessibility of total-lycopene. Phytoene (PT) and phytofluene (PTF), the precursors of lycopene, are colorless carotenes, which are attracting ...

Phytoene, phytofluene and ζ-carotene isomers from a Scenedesmus obliquus mutant
Phytochemistry, 1977Abstract A number of mutant strains of the green alga, Scenedesmus obliquus , when grown in the dark, accumulated ζ-carotene as their major carotenoid together with appreciable concentrations of phytoene and phytofluene. The phytoene was almost entirely the 15- cis isomer, and phytofluene was also present mainly as the 15- cis form, whereas the ζ ...

Free radical scavenging properties of Lycopene (LYC), Phytofluene (PF), and Phytoene (PE) are studied experimentally, considering the electron transfer mechanism and using the ABTS(•+) decolouration assay. Density Functional Theory is used to obtain the theoretical UV-visible spectra of ABTS (neutral and cation) and to determine the free radical ...

Journal of Food Composition and Analysis, 2012
Abstract Dietary carotenoid intake has been associated with a low incidence of several chronic diseases, including cardiovascular complications, cancer, and macular degeneration. While food composition and intake of some carotenoids such as β-carotene and lycopene is frequently available, information on the contribution of less studied ...

Phytofluene ex tomatoes is subject to cis-trans isomerization. The native form in the tomatoes studied is a relatively thermostable but photosensitive cis compound that may rearrange spontaneously or when illuminated or under the catalytic influence of iodine in light. It then yields the more stable all-trans form possessing stronger adsorbability. The

Determination of serum phytofluene and retinol
Clinica Chimica Acta, 1973Abstract A fluorimetric method is described for measuring levels of retinol and phytofluene in 200 μl serum. The serum levels of retinol and phytofluene were measured in 20 fasting individuals. The mean serum phytofluene concentration was 4.6 μg/ 100 ml, standard deviation 3.1 μg/100 ml; the mean retinol concentration was 46.8 μg/100 ml, standard ...
