Metabolomics Reveals the Differences in Metabolic Profiles Among Three Quinoa Varieties of Different Colors and Their Potential Antioxidant Activities

open access: yesJournal of Food Biochemistry, Volume 2026, Issue 1, 2026.
Quinoa, as a whole‐nutrition grain, has broad application prospects in the field of human health. This study systematically analyzed the metabolic composition and functional differences of white, black, and red quinoa using UPLC–MS–based untargeted metabolomics.

Extraction of bixin from annatto seeds using supercritical carbon dioxide [PDF]

open access: yes, 2008
The solubility of 93% pure bixin in supercritical carbon dioxide (SC-CO2) and of the bixin present in annatto seeds (Bixa orellana L.) was measured. For the seeds, the measurements were made in a temperature range from 30 to 50o C and pressure between

Data_Sheet_8_Identifying Bixa orellana L. New Carotenoid Cleavage Dioxygenases 1 and 4 Potentially Involved in Bixin Biosynthesis.PDF

open access: yes, 2022
Carotene cleavage dioxygenases (CCDs) are a large family of Fe2+ dependent enzymes responsible for the production of a wide variety of apocarotenoids, such as bixin. Among the natural apocarotenoids, bixin is second in economic importance.

Topical Bixin Confers NRF2-Dependent Protection Against Photodamage and Hair Graying in Mouse Skin

open access: yesFrontiers in Pharmacology, 2018
Environmental exposure to solar ultraviolet (UV) radiation causes acute photodamage, premature aging, and skin cancer, attributable to UV-induced genotoxic, oxidative, and inflammatory stress. The transcription factor NRF2 [nuclear factor erythroid 2 (E2)

Microlasers Made Entirely from Edible Substances

open access: yesAdvanced Optical Materials, Volume 13, Issue 22, August 5, 2025.
Several types of microlasers made completely out of edible substances are developed. They can be embedded directly into edible products and enable the sensing of various parameters, including sugar concentration, pH, the presence of bacteria, and exposure to too‐high temperatures.

Carotenoids Modulate FoxO‐Induced Cell Cycle Arrest in Human Cancer Cell Lines: A Scoping Review

open access: yesFood Science &Nutrition, Volume 13, Issue 4, April 2025.
Carotenoids upregulated pro‐apoptotic and FoxO signalling clusters. Carotenoids downregulated PI3k/Akt signalling, TNF signalling and cell cycle regulation clusters. Carotenoids may induce cell cycle arrest via the FoxO signalling pathway. ABSTRACT Carotenoids, a class of antioxidants, have shown great potential for cancer management.

Gaudichaudione H Enhances the Sensitivity of Hepatocellular Carcinoma Cells to Disulfidptosis via Regulating NRF2‐SLC7A11 Signaling Pathway

open access: yesAdvanced Science, Volume 12, Issue 11, March 20, 2025.
Gaudichaudione H (GH) effectively activates NRF2 signaling and its target genes, such as SLC7A11, and pharmaceutical activation of NRF2‐SLC7A11 signaling pathway aggravates uptake of cysteine, disturbance of GSH synthesis, depletion of NADPH, and accumulation of disulfide molecules, ultimately leading to the formation of disulfide bonds between ...

The safety of annatto extracts (E 160b) as a food additive

open access: yesEFSA Journal, 2016
Following a request from the European Commission to EFSA, the EFSA Panel on Food Additives and Nutrient Sources added to Food (ANS) was asked to re‐evaluate the safety of annatto extracts, bixin‐based and norbixin‐based, when used as a food additive and ...
