Relationship Between Biogenic Amines and Free Amino Acid Contents of Winesand M...
Herbert, Paulo; Cabrita, Maria Joao; Ratola, Nuno; Laureano, Olga; Alves, ArmindaThe concentration of biogenic amines and free amino acids was studied in 102 Portuguese wines and 18 musts from Alentejo demarcated (D.O.C.) regions. Most wines were commercial, except for 38 monovarietals obtained by micro vinification. Musts from the varieties used to produce the latter wines were also studied. Both biogenic amines and free amino acids were analyzed by HPLC using fluorescence detection for th...

Laureano, Olga; Ricardo-da-Silva, Jorge M.; Ó-Marques, João do; Reguinga, RuiThe purpose of the present work was to study the evolution of condensed tannins according to their degree of polymerization in seeds, pulp and skins, along the maturation using Cabernet Sauvignon and Tinta Roriz (Vitis vinifera L.) varieties. Additionally for this study a witness of each variety was compared with two modalities of fruit pruning, one of 50% and another one of 75%.
