Managing Apple Maturity and Storage to Increase the Quality of Virginia Hard Ciders
… differences in concentration of some individual polyphenols determined by UPLC-MS were observed in ciders made from fruit harvested at different stages. For example, cider made from optimally mature Dabinett had over 250% the concentration of procyanidin B5 that was found in cider made from fruit …

Physicochemical characterization of ten blackcurrant (Ribes nigrum) cultivars, their bioactivity related to type 2 diabetes and inflammation, and chemical changes after lactic acid fermentation
… The juice was analyzed by density, pH, BRIX, total acidity, viscosity, and color. For phenolic analysis, total polyphenols (TP), total anthocyanins (TA), total condensed tannins (TT), and quantification of the four major anthocyanins were completed. Antioxidant capacity and inhibition of …

Postprandial Effects of Pecans Ingestion on Plasma Level of Nutrients, Polyphenolic Compounds and Biomarkers of Antioxidant Status in Human Volunteers
… impact of pecan consumption on concentration of total plasma polyphenols and their peak concentration over time. 2) to measure the effect of a pecan diet on postprandial levels of plasma lipid peroxidation and on plasma antioxidant capacity. Sixteen healthy subjects participated in our randomized …

Anti-Diabetic and Anti-Obesity Activities of Cocoa (Theobroma cacao) via Physiological Enzyme Inhibition
… there were significant decreases (p<0.05) in total polyphenols, flavanols, and anthocyanins between the two sets of unfermented and fermented cocoa extracts (CEs). All CEs effectively inhibited α-glucosidase (lowest IC50 = 90.0 ug/mL for UL) and moderately inhibited α-amylase (lowest IC50=183 …

Functionality of Azadirachta indica A. Juss (neem) in beverages
… teas- green and black tea. We found that the total polyphenols and anti-oxidant activities in green and black tea are far higher than in neem, possibly due to the presence of flavan-3-ols in these teas. However, we used LC-ESI-MS/MS to identify specific flavonols- myricetin, quercetin and …
