DPPH Radical-Scavenging Activity and Polyphenol Content in Dried Fruits [PDF]

open access: yes
The 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging activity and polyphenol content of 25 dried fruits were evaluated and compared with fresh fruits. The contribution of ascorbic acid to this activity was also determined.

1H NMR spectra representing the competitive ability of gallic acid, chlorogenic acid and vanillic acid to neutralize the °DPPH radical in DMSO-d6: (A) gallic acid + the °DPPH radical, (B) chlorogenic acid + the °DPPH radical, (C) vanillic acid + the DPPH radical and (D) mixture of the three phenolic acids + the °DPPH radical.

open access: yes, 2015
The signals labeled with an asterisk are attributed to the °DPPH radical.

Defect‐engineered tungsten oxide nanowires as redox‐metabolic nanozymes for gut inflammation‐infection syndromes

open access: yesBMEMat, EarlyView.
Defect‐engineered WO3 nanowires serve as a multifunctional nanozyme platform to treat IBD complicated by Salmonella co‐infection. By integrating catalytic ROS/RNS scavenging and targeted metabolic interference of pathogens via molybdenum substitution, these nanowires effectively resolve intestinal oxidative stress, inhibit infection, and restore ...

Processing‐Induced Changes in Bioactive Compounds, Physicochemical, Nutritional, and Sensory Properties of Asian Salted Noodles Fortified With Red Beetroot Flour

open access: yesCereal Chemistry, EarlyView.
ABSTRACT Background and Objectives Asian salted noodles (ASN) are popular in East and Southeast Asia and in parts of Europe and the Americas. However, ASN are deficient in certain nutrients (e.g., vitamins, minerals, and dietary fiber) and bioactive compounds.

DPPH radical scavenging test.

open access: yes, 2015
Comparison of the antioxidant ability in the DPPH radical scavenging test of Millo Corvo (accumulating anthocyanins and no carotenoids), F2 segregating white seed (lacking anthocyanins and carotenoids) and Scagliolo cultivar (accumulating carotenoids ...

Phenolic‐Associated Dietary Fiber Ingredients From Agro‐Industrial Residues: Processing‐Dependent Identity and Food‐Grade Translation

open access: yesChemFoodChem, EarlyView.
Agro‐industrial residues contain dietary fiber and phenolics, but coexistence alone does not establish a phenolic‐bound ingredient. Processing‐dependent identity is verified through fraction‐specific analysis and common‐basis mass balance. Food‐grade translation requires final‐product performance, sensory acceptance, safety, and claim‐matched ...

Sequential Pressurized Liquid Extraction of Food Matrices: Fractionation, Selectivity, and Scale‐Up

open access: yesChemFoodChem, EarlyView.
Sequential pressurized liquid extraction separates food‐processing side streams into chemically distinct fractions by changing solvent polarity and operating conditions across stages. Lipophilic and phenolic compounds are recovered selectively, while co‐extraction is reduced.

Perspectives in biomedicine: Superfoods and antioxidant power classification

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract The market value of natural food antioxidants will double to 8 billion USD by 2033, driven by a global consumer demand for ‘clean label’ products and proactive wellness solutions. However, the industrial application and health labelling (commercial brands) of these compounds remain severely constrained by inconsistent analytical methods.
