Deciphering the catalytic and pharmacological mechanisms of Coptis chinensis herbzymes to renovate intestinal microenvironment for colitis alleviation

open access: yesBMEMat, EarlyView.
The synthesized CCzymes possess both antioxidant enzyme activity and pharmacological properties inherent to Coptis chinensis. By their antioxidant enzyme activity, CCzymes can attenuate oxidative stress within the inflammatory region of ulcerative colitis (UC), while their pharmacological activity acts on macrophage polarization and the intestinal ...

Nano‐networks via reaction‐induced self‐assembly coordinate spatiotemporal multi‐drug delivery for acute kidney injury therapy

open access: yesBMEMat, EarlyView.
Multifunctional nano‐networks (NNWs) are prepared via reaction‐induced self‐assembly (RISA) of spermidine (SPD), epigallocatechin gallate (EGCG), 2‐formylphenylboronic acid (2‐FPBA), and deferoxamine (DFO) through dynamic iminoboronate bonds. These NNWs leverage the oxidative AKI microenvironment to trigger disintegration, enabling site‐specific ...

2D copper nanozyme patches facilitate bone regeneration via interfacial modulation of osteoclast‐osteoblast dynamics

open access: yesBMEMat, EarlyView.
This study develops a nano‐enzyme patch (ezPatch) targeting bone interfaces. Utilizing ligand‐to‐metal charge transfer (LMCT) catalysis and bone‐targeting ligands on copper nanosheets, ezPatch simultaneously scavenges reactive oxygen species (ROS) and generates oxygen in situ at bone‐losing sites.

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 ...

Formation and Characterization of Insoluble Anthocyanins‐λ‐carrageenan Biopolyelectrolyte Complexes: Structural Morphology, Thermal Stability, and Release Dynamics

open access: yesChemFoodChem, EarlyView.
Insoluble biopolyelectrolyte complexes formed between blackberry anthocyanins and λ‐carrageenan are investigated. Optimal complexation occurs at low carrageenan ratios and acidic pH, producing porous hydrogel‐like structures with enhanced thermal stability.

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,

Impact of storage time and solvent type on 2,2-diphenyl-1-picrylhydrazyl free radical stability

open access: yesCase Studies in Chemical and Environmental Engineering
The effect of storage time and solvent on 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical stability was studied using electron spin resonance. Tetrahydrofuran affected the g-factor due to a rearrangement within the DPPH structure that changed the radical ...

Antioxidant Activity and Inhibition of Carbohydrate Hydrolyzing Enzymes by Underutilized Parts From Some Plant‐Based Foods and Their Effect on Postprandial Hyperglycemia

open access: yesFood Chemistry International, EarlyView.
The underutilized parts viz: pawpaw seed, banana, plantain, and potato peels showed promising antioxidant and inhibition of α‐amylase and α‐glucosidase activities (IC50 values ≤ 100 μg/mL). Similarly, pawpaw seed, banana, plantain, and potato peels reduced postprandial hyperglycemia in sucrose‐ and maltose‐induced hyperglycemia in rats.

Phenolic Profiles, Antioxidant Properties and Predicted Glycaemic Index of Bread Sweetened With Date Syrup in Comparison With Granulated Sugar

open access: yesFood Chemistry International, EarlyView.
Date syrup are used as sweetener in bread. Bread with date syrup had superior phenolic composition, better antioxidant properties and carbohydrate hydrolysing enzymes while bread with granulated sugar had higher predicted glyceamic index. The study concluded that date syrup could be the next though‐out ingredient for dual purpose in bread. ABSTRACT The
