Supplementation with cactus pear (Opuntia ficus-indica) fruit decreases oxidative stress in healthy humans: A comparative study with vitamin C [PDF]

, 2004
Background: Cactus pear (Opuntia ficus-indica) fruit contains vitamin C and characteristic betalain pigments, the radical-scavenging properties and antioxidant activities of which have been shown in vitro.

Betanin inhibits the myeloperoxidase/nitrite-induced oxidation of human low-density lipoproteins [PDF]

, 2007
Production of nitrogen dioxide by the activity of myeloperoxidase (MPO) in the presence of nitrite is now considered a key step in the pathophysiology of low-density lipoprotein (LDL) oxidation.

Cytoprotective effects of the antioxidant phytochemical indicaxanthin in beta-thalassemia red blood cells [PDF]

, 2006
Antioxidant phytochemicals are investigated as novel treatments for supportive therapy in b-thalassemia. The dietary indicaxanthin was assessed for its protective effects on human b-thalassemic RBCs submitted in vitro to oxidative haemolysis by cumene ...

Clarification of purple cactus pear juice using microfiltration membranes to obtain a solution of betalain pigments

Brazilian Journal of Food Technology, 2015
Summary Betalains are fruit pigments possessing health-giving properties. To isolate the pigments, the juice must be separated from the fruit matrix, which contains biopolymers. The aim of this study was to clarify cactus pear juice by microfiltration to

Evaluation of Natural Pigments Production in Response to Various Stress Signals in Cell Lines of Stenocereus queretaroensis

Plants, 2022
Stenocereus queretaroensis (F.A.C. Weber ex Mathes.) Buxb is a cactus that has long been used as a source food in central and northern México. Its fruits, commonly called pitayas, biosynthesize high amounts of betalains. These molecules are water-soluble

Functionally complementary bacterial inoculant coordinates arbuscular mycorrhizal fungi to improve Angelica sinensis root yield and quality

iMetaOmics, EarlyView.
Comprehensive understanding of how diverse PGPR strains enhance the rhizosphere microenvironment remains a considerable challenge. Here, we provide experimental evidence that a functionally synergistic composite microbial formulation can markedly enhance growth performance and improve the quality attributes in Angelica sinensis.

Encapsulation of betalains from beetroot pomace in protein-gum blends: characterization, antioxidant and color stability analysis

Applied Food Research
Betalains exhibit strong potential as natural food colorants; however, their practical application is limited by instability under exposure to heat, oxygen, and light.

Kinetic Modelling of Betalain Stability and Color Changes in Yogurt During Storage

Polish Journal of Food and Nutrition Sciences, 2021
Assessment of the storage stability of betalains added to food during processing is crucial to estimate the shelf-life of colored food products and the potency of natural food colorants.
