Grape and wine phenolics: Observations and recent findings Ciencia e Investigación Agraria
Kennedy,James A.
What consumers taste in wine is the culmination of management practices from the vineyard to the glass. As researchers, in order to have control over the composition of wine at the time of consumption, it is important to understand how production practices affect wine chemistry. Because phenolic compounds are so important to the overall quality of wine, they are the subject of intense investigation throughout the world. This review is a summary of current knowledge and some recent findings that have taken place in this area.

Antioxidant activity and prevention of pork meat lipid oxidation using traditional Mexican condiments (pasilla dry pepper, achiote, and mole sauce) Ciênc. Tecnol. Aliment.
Alvarez-Parrilla,Emilio; Mercado-Mercado,Gilberto; La Rosa,Laura Alejandra De; Díaz,José Alberto López; Wall-Medrano,Abraham; González-Aguilar,Gustavo Adolfo.
Considering the extensive use of hot peppers and spicy sauces in the Mexican cuisine, in the present paper, three widely consumed Mexican condiments (mole sauce, achiote, and pasilla hot pepper) were analyzed for their total phenols, flavonoids and proanthocyanidins, antioxidant activity, and protective effect against lipid oxidation in chopped pork meat. All samples were extracted first with methanol and then with acetone, and the extracts were compared. Pasilla pepper showed the highest phenolic and flavonoid content in both solvents, followed by mole and achiote. Achiote showed the highest proanthocyanidin concentration. All samples showed high antioxidant activity, and good correlations with phenolic compounds and flavonoids, while no correlation was...
