Intake and Bioaccessibility of Total Polyphenols in a Whole Diet

Food Chemistry, 2007
The knowledge of dietary intake of polyphenols and their bioaccessibility in the human gut are key factors in assessing their significance in human health. The aim of this work was to estimate the amount of total polyphenols consumed in a whole diet (Spanish Mediterranean diet) and their intestinal bioaccessibility.

Polyphenols Excreted in Urine as Biomarkers of Total Polyphenol Intake

Bioanalysis, 2012
Nutritional biomarkers have several advantages in acquiring data for epidemiological and clinical studies over traditional dietary assessment tools, such as food frequency questionnaires. While food frequency questionnaires constitute a subjective methodology, biomarkers can provide a less biased and more accurate measure of specific nutritional intake.

The effect of roasting on the total polyphenols and antioxidant activity of coffee

Journal of Environmental Science and Health, Part B, 2020
The total polyphenolic content and the antioxidant activity have been analyzed in ground beans of green, light, medium and dark roasted coffee by UV-VIS spectrometry. Water coffee extracts showed the highest levels of polyphenols in green and light roasted coffees where the total polyphenolic content (TPC) ranged from 49.19 ± 0.70 to 74.05 ± 0.28 and ...

A METHOD FOR ESTIMATING TOTAL POLYPHENOLS IN BEER

Journal of the Institute of Brewing, 1973
A procedure is described whereby polyphenols in beer are extracted under acid and alkaline conditions. These fractions are analysed to obtain the net amount of polyphenols and these are in turn used as standards for calibration in developing a colorimetric method for the determination of total polyphenols in beer.

Total polyphenol intake, polyphenol subtypes and incidence of cardiovascular disease: The SUN cohort study

Nutrition, Metabolism and Cardiovascular Diseases, 2019
Polyphenol-rich diets have been associated with reduced risk of cardiovascular disease (CVD). However, few prospective epidemiological studies have examined the relationship between classes of ingested polyphenols and risk of CVD. Our aim was to evaluate the association between polyphenol intake and risk of major cardiovascular events in a prospective ...

Quantification by UHPLC of total individual polyphenols in fruit juices

Food Chemistry, 2013
The present work proposes a new UHPLC-PDA-fluorescence method able to identify and quantify the main polyphenols present in commercial fruit juices in a 28-min chromatogram. The proposed method improve the IFU method No. 71 used to evaluate anthocyanins profiles of fruit juices.

Contribution of Individual Polyphenolics to Total Antioxidant Capacity of Plums

Journal of Agricultural and Food Chemistry, 2003
To study the effect of polyphenolics on antioxidant capacities of plums, the amounts of total phenolics, total flavonoids and individual phenolic compounds, and vitamin C equivalent antioxidant capacity (VCEAC) of eleven plum cultivars was determined.

BioElectronic Tongue for the quantification of total polyphenol content in wine

Talanta, 2012
This work reports the application of a BioElectronic Tongue (BioET) in the estimation of polyphenol content in wine. The approach used an array of enzyme biosensors capable of giving a wide and complete response of the analyzed species, plus a chemometric processing tool able to interpret the chemical signals and extract meaningful data from the ...
