Improving Antioxidants and Physicochemical Properties of Wild Rice Noodles by Fortification With Carrot Powder

open access: yesCereal Chemistry, EarlyView.
ABSTRACT Background and Objectives Wild rice (WR), a nutritious cereal rich in phytochemicals, remains underutilized despite its health benefits. This study explored deep purple (DP), purple sun hybrid (PSH), purple haze (PH), cosmic purple (CP), and vistaric sky blue (VSB) carrot powders as fortificants in WR noodles at 10%, 20%, and 30% levels in ...

Genistein: a novel anthocyanin synthesis promoter that directly regulates biosynthetic genes in red cabbage in a light-dependent way

open access: yesFrontiers in Plant Science, 2016
Genistein (GNT), an isoflavone, is used in the clinical treatment of various health disorders. GNT is found in primary food source plants and some medical plants. However, studies on the functions of GNT in plants are rarely reported.

Design of a Fluorescent Boronic Acid‐Functionalized Pyranoflavylium Receptor to Host and Release Diol‐Rich Bioactive Analytes in a pH‐Dependent Manner

open access: yesChemFoodChem, EarlyView.
This work presents a pH‐responsive ON–OFF fluorescent system based on a novel pyranoflavylium dye functionalized with a boronic acid receptor. The receptor exhibits a markedly higher affinity for the catechol‐containing polyphenol (+)‐catechin than for conventional diol‐rich molecules such as glucose and lactic acid.

Spouted bed drying parameters and adjuvant effects on polyphenol retention and antioxidant activity in mango peel powders

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Spouted bed drying of mango peels with colloidal SiO2 and corn starch produces a free‐flowing powder with reduced agglomeration, increased drying yield, and preserved antioxidant and polyphenol content. Abstract The production of polyphenol‐rich powders is a promising strategy for valorizing agro‐industrial byproducts. This study evaluated drying yield,

Nanocrystallization of Anthocyanin Extract from Red-Fleshed Apple ′QN-5′ Improved Its Antioxidant Effect through Enhanced Stability and Activity under Stressful Conditions

open access: yesMolecules, 2019
Red-flesh apples are known as functional fruits because of their rich anthocyanin. The anthocyanin content of the red flesh apple cultivar ′QN-5′ we bred can reach 361 mg·kg−1 (FW), and showed higher scavenging capacity to DPPH ...

Elucidating the genetic basis of antioxidant status in lettuce (Lactuca sativa). [PDF]

open access: yes, 2015
A diet rich in phytonutrients from fruit and vegetables has been acknowledged to afford protection against a range of human diseases, but many of the most popular vegetables are low in phytonutrients. Wild relatives of crops may contain allelic variation
