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. This review aimed to present a comprehensive overview of research on lycopene, phytoene, and phytofluene obtained from waste and by-products.

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 ...

The occurrence of phytofluene in green plant organs
Archives of Biochemistry and Biophysics, 1953Abstract By means of an improved method, the presence of very small quantities of phytofluene was revealed in chlorophyll-containing tissues of all plants examined, viz. 21 species representing 18 families of vascular plants.

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

Preparation and spectral characteristics of all-trans-and a cis-phytofluene
Archives of Biochemistry and Biophysics, 1953Abstract A method for the isolation of a cis - and all- trans -phytofluene is described, and some spectral data are given for these two compounds.

Abstract This paper reports the conversion of cis -[ 14 C]phytofluene to trans -[ 14 C|phytofluene and the conversion of the latter compound to trans -ζ-[ 14 C]carotene by a soluble enzyme system obtained from the plastids of red tomato fruits. Each of these radioactive compounds was also converted to labeled neurosporene, lycopenc, α-carotene ...

Abstract The conversion of cis -[ 14 C]phytofluene to trans -[ 14 C]phytofluene and the conversion of the latter to trans -ζ-[ 14 C]carotene by a soluble enzyme system obtained from plastids of tangerine tomato fruits is reported. Each of these compounds is also converted to cis -ζ-carotene, proneurosporene, prolycopene, neurosporene, lycopene ...

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 ...

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 ...

Abstract Carotenoids are dietary compounds of great interest in food science, nutrition and health due to the fact that some of them can be converted into retinoids exhibiting vitamin A activity, their role as natural colorants and a growing body of evidence indicating that they may provide health benefits.
