The Chemistry Behind the Folin–Ciocalteu Method for the Estimation of (Poly)phenol Content in Food: Total Phenolic Intake in a Mediterranean Dietary Pattern

open access: yesJournal of Agricultural and Food Chemistry, 2023
The Folin–Ciocalteu assay is a reference method for the quantification of total (poly)phenols in food. This review explains the fundamental mechanism of the redox reaction on which the method is based and looks at some of the practical considerations ...

Effects of monosaccharide composition on quantitative analysis of total sugar content by phenol-sulfuric acid method

open access: yesFrontiers in Nutrition, 2022
Phenol-sulfuric acid method is one of the most common methods applied to the analysis of total sugar content during polysaccharides study. However, it was found that the results obtained from the phenol-sulfuric acid method was generally lower than the ...

Bio-Based Alternatives to Phenol and Formaldehyde for the Production of Resins

open access: yesPolymers, 2020
Phenol–formaldehyde (PF) resin continues to dominate the resin industry more than 100 years after its first synthesis. Its versatile properties such as thermal stability, chemical resistance, fire resistance, and dimensional stability make it a suitable ...

Adsorption of Phenol on Commercial Activated Carbons: Modelling and Interpretation

open access: yesInternational Journal of Environmental Research and Public Health, 2020
Adsorption by activated carbons (AC) is an effective option for phenolic wastewater treatment. Three commercial AC, including coal-derived granular activated carbons (GAC950), coal-derived powdered activated carbons (PAC800), and coconut shell-derived ...

Identification of phenol- and p-cresol-producing intestinal bacteria by using media supplemented with tyrosine and its metabolites

open access: yesFEMS Microbiology Ecology, 2018
To identify intestinal bacteria that produce phenols (phenol and p-cresol), we screened 153 strains within 152 species in 44 genera by culture-based assay using broth media supplemented with 200 µM each of tyrosine and its predicted microbial metabolic ...

Phenol-Explorer: an online comprehensive database on polyphenol contents in foods

open access: yesDatabase J. Biol. Databases Curation, 2010
A number of databases on the plant metabolome describe the chemistry and biosynthesis of plant chemicals. However, no such database is specifically focused on foods and more precisely on polyphenols, one of the major classes of phytochemicals.

PHENOL COEFFICIENTS

open access: yesAmerican Journal of Public Health, 1921
The author states that a phenol coefficient indicates relative germicidal efficiency under laboratory conditions only, and has no practical value. Users of disinfectants ordinarily “follow directions,” and employ the dilutions recommended by the manufacturers.

Catalytic asymmetric dearomatization (CADA) reactions of phenol and aniline derivatives.

open access: yesChemical Society Reviews, 2016
Phenols are widely used as starting materials in both industrial and academic society. Dearomatization reactions of phenols provide an efficient way to construct highly functionalized cyclohexadienones.
